Maxillae notched, with a slight second notch and slight double prominence in the lower part.
In all, the mandibles have five teeth, the two lower ones being small: the maxillae are not notched: the outer maxillae are bilobed.
The maxillae have a small notch under the upper pair of spines; inferior part projecting and supporting two spines, placed one below the other, and equalling in size the upper pair.
The maxillae are always notched under the two or three large upper spines: the notch bears some fine spines: beneath the notch there are some large spines, and at the inferior angle some smaller ones.
The maxillae are small; there is a small notch beneath the two upper great spines, and a second notch near the inferior angle.
The maxillae are not notched; and carry one or two spines, near their inferior angle, nearly as large as the upper pair.
The outer maxillae are bilobed on their inner sides.
The maxillae are concave around the maxillary foramen, and external to this foramen is an elongated ridge about as in europaeus.
Majority of sutures open, but those on superior surface of rostrum between maxillae and premaxillae partly anchylosed.
Majority of sutures open, but maxillae and premaxillae anchylosed together above and on the sides.
At the middle of the beak the outline of the maxillae at a lower level is visible from above, which is not the case in bidens or europaeus.
At the middle of the beak the premaxillae are higher than the maxillae on which they rest.
The maxillae are much broader behind the notch than in bidens, and the anterior end of the malar forms the bottom of the notch.
In this skull the proximal end of the premaxillae and adjoining plate of the maxillae are somewhat less reflexed than in the Rugsund skull.
There is no basirostral groove, the edges of the maxillaebeing very thick in front of the maxillary notch.
Nearly all sutures between maxillae and premaxillae at end of rostrum, above and below, anchylosed together, but majority of others traceable.
The expanded portion of the maxillae and frontals broader in front of the orbit.
Over the orbit the maxillae are thick and beveled, but not raised as in bowdoini.
The pterygoids are cut off from the maxillae anteriorly by a very narrow band of the palatine, which connects with a broad band externally and a lanceolate segment internally.
These ends do not fit closely against the adjoining edge of the maxillae as in bidens, but leave a transverse vacuity, or trough, which is especially noticeable in the type-skull.
The two bones make but a narrow angle with the median line, instead of a wide one, as in bidens, and the surface of the maxillae between them is strongly convex instead of flat.
The principal ones are the breadth of the maxillae in front of the orbits, the presence of the malar in the base of the anteorbital notch, and the convexity of a part of the inferior surface of the pterygoids.
The pre-maxillae (which carry the incisor teeth) do not project in front, nor does the bony palate extend farther back than the end of the posterior molar teeth.
The pre-maxillae are very much reduced, so that the teeth they usually carry are generally wanting.
Pre-maxillae not produced far in front; hind border of bony palate not extending backwards beyond the median molar.
The second antennae, mandibles and two pairs of maxillae may also be claimed as of malacostracan type.
The variable first maxillae are seldom pediform, their function being concerned chiefly with nutrition, sensation and respiration.
The variability in form and function of the second maxillae is sufficiently shown by the fact that G.
This "leaf-footed" suborder has the appendages which follow the second maxillae variable in number, but all foliaceous and branchial.
The four segmented labium or proboscis encloses the lancet-like maxillae and mandibles.
The mandibles and maxillae are serrated and fitted for biting.
The external surfaces of the maxillae of Delorhynchus are pitted and ridged; Vaughn was unable to discern sculpturing of the corresponding surfaces in Colobomycter.
The differences between the maxillae of Colobomycter and Delorhynchus are most striking in the lack of canines in the latter and the correlated absence of modifications of the maxillary for support of canines.
Eugereon is a remarkable Permian fossil, with jaws that are typically hemipterous except that the second maxillae are not fused and with cockroach-like wings.
Maxillae with three tufts of fine bristles, separated by larger spines; caudal appendages uniarticulate; filamentary appendages attached to the prosoma.
The outer maxillae have the spines on their inner edges either continuous or divided into two groups, of which latter structure we have not hitherto had any very well characterised example.
Mandibles with three teeth; maxillae narrow, bearing only four or five pair of spines.
Maxillae without a notch, edge nearly straight, and spines very numerous: caudal appendages exceeding, by half, the length of the pedicel of the sixth cirrus.
The outer maxillae are bilobed in front, with a few short bristles on the outer side near the bottom.
Filaments attached to the pedicels of the second cirrus; two upper spines of the maxillae pectinated.
Maxillae with the inferior part of edge much upraised.
The maxillae have two or three large upper spines, the others being very thin; I believe the lower part is upraised and step-like, as in the hermaphrodite.
The mouth of these insects is suctorial, the maxillae forming a spiral proboscis which is coiled up between the large labial palpi when not in use (see Plate I.
With regard to their use, it is said to be to retain the insect which the animal has seized, and to facilitate the compression which the maxillae exercise upon it for the extraction of the nutritive matter[1361].
We see, in the antlia, that the maxillaereceive their vast elongation at the expense of all the other organs, except the labial palpi.
Ligula or palate within the mouth, accompanied by the organs of manducation--a pair of mandibles and maxillae and an upper and lower lip, or their representatives.
In the genus Nemognatha of Illiger, the maxillae of the male are elongated, narrow, setiform, and often involute or spiral, like those of a bee or a butterfly.
In some Neuropterous larvae, as those of the Libellulina MacLeay, the maxillae are of a substance quite as solid and horny as the mandibles, which in every respect they resemble[262].
Between the two maxillae in the larvae of most of the insects under consideration is a part termed by Reaumur the middle division of the under-lip, but which is in fact analogous to the whole of that organ in the imago.
If any part of the maxillae can act upon each other, it is these organs or palpi; but it is evident they are not calculated for mastication, although they may assist in the retention of the substance to be masticated.
The most important excretory or renal organs of the Crustacea are two pairs of glands lying at the base of the antennae and of the second maxillae respectively.
The mandibles and first maxillae are transformed into stylets, often barbed toward the tip; these work to and fro within the groove of a stout-jointed beak (rostrum) which is formed by the union of the second maxillae.
Bb) being powerful, and the first pair of maxillae (fig.
The mandibles are strong, adapted for biting the vegetable substances on which these beetles feed, and the palps of the second maxillae have three segments.
Rostrum (seen from above) triangular, tapering from the base to the apex; upper and outer edges ofmaxillae at base of rostrum raised into low roughened tuberosities.
Maxillae supporting large, incurved, compressed bony crests, which overarch the nostrils and base of the rostrum, and almost meet in the middle line above.
Small rough eminences on the outer edge of the upper surface of the maxillae at base of rostrum.
Premaxillae concave in front of the nostrils, as wide at the middle of the rostrum as at the base, and nearly or completely concealing the maxillae in the anterior half of this region.
The maxillae are narrow at the end and slant inward.
The labium is short and the maxillae straight, as in Agroeca and Anyphaena, but wider at the base (fig.
The maxillae are straight in front and have a slight projection at the outer corners, where there are two or three stiff hairs.
The labium is long and the maxillae slightly widened at the end, or with the outer corners rounded off and sometimes a crease or depression in the middle.
The labium and maxillae are a little longer than usual and are partly covered by the first legs.
The maxillae are narrow in the middle and flat and wide at the ends.
The maxillae are long, a little widened in the middle and pointed at the ends.
The maxillae are much thickened and the bases of the palpi spread wide apart (fig.
On the under side the ends of the mandibles and the maxillaeare black.
The labium is not longer than wide, and the maxillae are straight, with the sides parallel.
The maxillae are short, often as short as wide, and parallel or a little divergent and rounded at the ends, never pointed or turned inward.
Between the maxillae is a small piece called the labium, and between the legs is a larger oval piece called the sternum.
The labium is short and the maxillae with straight sides.
The maxillae are inclined toward each other so that they meet in front of the labium.
The maxillae are large, and rounded on the outer corners.
The palpi of both maxillae and labium are wholly wanting in Hemiptera and the flexible needle-like maxillae and mandibles are enclosed in the tubular labium.
Try to separate the two maxillae which compose it.
Crustacea; by the presence between the mandibles and maxillae of a pair of appendages (superlinguae or maxillulae), fig.
Color darker; skull smaller in all measurements taken; auditory bullae noticeably smaller; width across zygomatic processes of maxillae less.
Skull of medium size; rostrum wide; nasals short, projecting but slightly anteriorly to incisors; zygomatic processes of maxillae heavy; bullae not greatly inflated.
Sutures widely open between the maxillae and nasals and between the premaxillae and nasals.
The palate is broken longitudinally and the two maxillaeare slightly out of normal position.
Further, in the bugs, the labium is long and tubular, while the mandibles and maxillae are often modified into sharp, stiff bristles that work within the tube, the whole thus forming a combined piercing and sucking arrangement.
