In the case of cattle-egrets (Bubulcus coromandus) the custom of shooting them when on the nest has given place to a more humane and more sensible method of obtaining their nuchal plumes.
We must regard the nuchalplate as a true vertebra, modified, it is true, in its formation and development by its particular functions.
The nuchal plate, continuous at its right and left posterior angles with the root of the mid-foot, and corresponding to the nuchal cartilage of Sepia.
The nuchal plate, identical with the nuchal cartilage of Sepia (see fig.
The morphological significance of this nuchal lamella, as seen both in Nautilus and in Sepia, is not obvious.
In Sepia a cartilaginous development occurs here immediately below the integument forming the so-called "nuchal plate," drawn in fig.
In Octopoda there is no nuchal cartilage, but two band-like "dorsal cartilages.
The nuchal skeleton is a non-cellular laminated thickening of basement-membrane underlying that portion of the stomochord which lies between the above-mentioned pouches and the orifice into the throat.
It is not a simple diverticulum of the collar-gut, but a complex structure possessing paired lateral pouches and a ventral convexity (ventral caecum) which rests in a concavity at the front end of the body of the nuchal skeleton (fig.
Openings between the free ends of developing ribs, between nuchal bone and first rib, and, between pygal bone and last rib; limited laterally by peripheral bones; variable in shape.
Of the costoperipheral fontanelles, the anterior one (between first rib and nuchal bone) closes first and the posterior one (between last rib and pygal bone) last.
By the presence of a number of small nuchal shields, while G.
It is not much easier to suppose the ancestor to have been a nondescript, with a compromise between the developed characters of each, with quills buff, malar stripes neither black nor red, with a trace of nuchal crescent, and so on.
Is it seriously suggested that there is some element common to the "conditions" of such an area which demands a nuchal crescent in the Flickers, though the birds of the cafer area, almost equally varied, can dispense with the same character?
The development of the scarlet nuchal crescent in auratus and the absence of this conspicuous mark in cafer constitute from the physiological point of view the most remarkable pair of differences.
A bird may have the general colouration of true cafer combined with a well-developed nuchal crescent, or nearly pure auratus with the red malar stripes of a cafer.
Among all the birds I have seen in America or in England I have not yet found one having the malar patches black without any nuchal crescent.
Like Streptosyllis in having the pharynx strongly sinuous and unarmed and in lacking nuchalflaps such as characterize Amblyosyllis.
Imbricatum similarly presentsnuchal appendages, but these are three in number on each side and slender, instead of two broad, subelliptic lobes.
Nuchal cirri short and conical, much shorter than the peristomium, transversely wrinkled or sometimes distinctly annulated.
We returned the following morning and found the male bird (distinguishable by his red nuchal patch) again on the nest.
Adult female: Like male but carmine nuchal patch reduced or wanting; throat-patch reduced by white of chin.
Of twenty-seven males from Vancouver Island nine possess in whole or in part the scarlet nuchal patch characteristic of auratus.
Cranial shield wide, rounded anteriorly, deeply indented in nuchal margin; orbital rim not apparent in dorsal aspect.
It has no nuchal spine, and no trace of paired fins is preserved.
It is not known that Dittodus possesses the nuchal spine, although detached spines like those of Pleuracanthus lie about in remains called Didymodus in the Permian rocks of Texas.
That the black nuchal collar of our common Grass-snake is actually formed by the fusion of the spots of three originally distinct series has been proved by tracing the development of the markings in the embryo.
The lateral parts of the nuchal overlie the second pair of ribs.
Large females of spinifer and ferox acquire enlarged, flattened knobs in the nuchal region and posteriorly in the center of the carapace.
The marginal rim is widest at the posterior end of the carapace and lacking in the nuchal area.
As growth proceeds, the single, transversely-oriented, fontanelle of young turtles that separates the nuchal from the first neural and first pair of pleurals divides into two fontanelles that generally decrease in size and finally disappear.
The distributional picture is somewhat complicated because some individuals having the torquata-type of nuchal pattern also have a faint nape stripe.
Snakes having the ochrorhyncha-type of nuchal pattern are found on the Mexican Plateau from Michoacan northward into the desert regions of Sonora and the southwestern United States.
Specimens from the three mentioned localities have the darknuchal spot bordered anteriorly by a pale blotch.
Individuals having an incomplete nuchalcollar have been found at Maravatio and at Zinapecuaro in the northern part of the state; in this character these specimens resemble S.
An exception is Hypsiglena torquata dunklei from Forlon and San Fernando, Tamaulipas; it has the torquata-type of nuchal pattern.
The pale nuchal area was a cream-color, and the iris was grayish red.
Although the nuchal of Chrysemys limnodytes is incomplete, it can be distinguished from the nuchals described by Hay as types of his several fossil Emydids.
Hay attached considerable taxonomic importance to the characters of the nuchal and I find its characters to be fairly constant in the specimens of Emydidae examined.
The position of the nuchal segment permits a measurement of the part which is to form the pygidium, and shows that that shield made up 30 per cent of the entire length.
The last pair is attached to appendifers beneath the nuchal segment, and the first pair beneath the third glabellar furrows.
What they consider the first thoracic segment (fused with the head) seems to me to be the posterior part of the cephalon and it shows at the back a narrow transverse area which is at least analogous to the nuchal segment of the trilobite.
The great nuchaland genal spines and the large marginal sessile eyes, coupled with the almost total lack of thoracic and abdominal test, give it a bizarre appearance which may obscure its real relationships.
This genus differs from Hypsipetes in having longer rictal bristles, the longest being decidedly more than one-half as long as the tarsus, and in having the nuchal hairs more strongly developed.
Without a distinct fleshy eye-wattle and without an elongated nuchal crest.
The young male is like the adult female but lacks the nuchal band and under parts have no vinaceous wash; wing-coverts and feathers of breast tipped with yellowish brown.
Differs from the male in having the back, rump, wings, and tail brown, in lacking the nuchal patch and breast crescent, and in having the blue of head and throat somewhat duller and the breast bluish gray.
Similar to male but larger; throat and chin black; chestnut of breast continued above as a wide nuchal collar.
Under parts bright yellow or strongly tinged with yellow; nuchal hairs longer.
The top of the neural arch almost or quite meets a blunt outgrowth from the nuchal plate.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "nuchal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
