The subgenus Sorex in North America should include only the following species: S.
Under the latter view Camellia is regarded as a subgenus or section of Thea.
In the subgenus Neotamias interspecific variation in the baculum is considerable, but the general plan of structure remains constant.
In the subgenus Eutamias and in the genus Tamias the infraorbital foramen is rounded, whereas in most species of the subgenus Neotamias the foramen is slitlike.
The same condition obtains in the shape of the infraorbital foramen which is subovate to rounded in the subgenus Neotamias and always rounded in the other chipmunks.
In the subgenus Eutamias, the baculum "tapers gradually from base to tip, the distal portion upturned in an even curve and slightly flattened .
Examination of series of bacula of the subgenus Neotamias and the genus Tamias indicates, as in the case of the mallei, that there is slight individual variation and slight variation with age.
Intraspecific variation in the subgenus Neotamias is slight, consisting of differences in size.
The interorbital region is more constricted in most species of the subgenus Neotamias than in the subgenus Eutamias and the genus Tamias.
In Eutamias townsendii, however, the infraorbital foramen is rounded as much as in the subgenus Eutamias and in the genus Tamias.
Further, the base of the postorbital process of the frontal usually is narrower (relative to the length of the process) in the subgenus Neotamias but there is a gradation in this feature in Neotamias culminating in the species E.

To this genus or subgenus Scarabaeus Syphax, Antaeus, Titanus, &c.
In labelling your specimens, you should stick the appellation of the genus or subgenus with a pin before the species that belong to it.
This brings us down to the lowest group formed out of genera and subgenera: or the family, which from its principal genus is named Brachinidae, and which leads us to the genus Brachinus, and the subgenus Aptini.
Microtines of the subgenus Stenocranius from continental areas of Alaska and Northwestern Canada are represented in collections by a few specimens from widely separated localities.
Omitting the species with permanent teeth on the shaft of the vomer (subgenus Salar), he finds among the salmon proper only two species, Salmo salar and Salmo trutta.
The most highly specialized of its species have the teeth deep blue in color, a character which marks the genus or subgenus Pseudoscarus.
The Chilean and Peruvian Andes and Patagonia are the homes of two peculiar deer locally known as guemals (huemals), and constituting the subgenus Xenelaphus, or Hippocamelus.
The second group of the genus Cervus, forming the subgenus Pseudaxis, is typified by the handsome little Japanese deer, or sika, C.
Blastoceros) dichotoma, representing a subgenus in which the complex antlers lack a basal snag, while the hair of the back is reversed.
Including all these deer except one in the genus Mazama (of which the typical representatives are the South American brockets), the North American species constitute the subgenus Dorcelaphus (also known as Cariacus and Odocoileus).
Nearly allied to the preceding is the barasingha or rucervine group (subgenus Rucervus), in which the antlers are of a different and generally more complex character.
Many species of the subgenus Euspongilla, the typicalsubgenus of Spongilla (including S.
This species is easily distinguished from its allies of the subgenus Euspongilla by its adherent gemmules with their (usually) multiple apertures and rough external surface.
The status of Potamolepis, Marshall, originally described from the Lake of Galilee, is very doubtful; possibly some or all of its species belong to the subgenus of Spongilla here called Stratospongilla (p.
Among these species Corvospongilla lapidosa and our representatives of the subgenus Stratospongilla are noteworthy.
The subgenus Eunapius is, like Euspongilla, cosmopolitan.
The two sponges are easily distinguished from all others in the subgenus Euspongilla by the upright and regular arrangement of their gemmule-spicules, for although in S.
The species in this subgenus are closely allied and must be distinguished rather by the sum of their peculiarities than by any one character.
Sponges of this subgenus form crusts or sheets on solid submerged objects.
Their gemmules are intermediate in structure between those of that subgenus and those of Euspongilla.
Probably Uraguaya, Carter, should be regarded as a subgenus of Trochospongilla with an unusually solid skeleton; it is peculiar to S.
Lateral view of right side, unless otherwise indicated, of the baculum in each of the species of chipmunks (subgenus Neotamias) of western North America: 1.
In the species of the subgenus Neotamias the proximal part of the baculum is termed the shaft, and the distal upturned part is termed the tip.
California--as well as elsewhere within the geographic range of the subgenus Neotamias.
The second subgenus gave us some Didactylus specimens three to four decimeters long, streaked with yellow, their heads having a phantasmagoric appearance.
Defn: Any one of several species of fresh-water ducks, especially those belonging to the subgenus Mareca, of the genus Anas.
Defn: A subdivision of a genus, comprising one or more species which differ from other species of the genus in some important character or characters; as, the azaleas now constitute a subgenus of Rhododendron.
Grossularia a subgenus of Ribes, including the gooseberry, fr.
Defn: Any one of several species of feline animals of the genus Felis, and subgenus Lynx.
Cyprinid fishes of the Subgenus Cyprinella of Notropis.
Systematic status of the Subgenus Cyprinella, with a key to the species exclusive of the lutrensis-ornatus complex.
In the genus Peromyscus, only Peromyscus floridanus (subgenus Podomys) possesses a knoblike short process on the incus similar to that in B.
If Baiomys were treated as a subgenus of the genus Peromyscus, there would be adequate justification for including in the genus Peromyscus a number of other genera, some of them occurring in South America.
True in 1894 regarded them as composing a distinct subgenus of Sitomys, Baiomys.
Vesperimus, or Onychomys (which had been considered as a subgenus of Hesperomys until 1889).
The names of kinds I do not consider as belonging to the subgenus (and genus) are excluded.
In the subgenus Trinomys, where the aristiforms attain their maximum development, they are still strong and conspicuous on the rump and sometimes around the base of the tail.
In all members of the subgenus Proechimys, these ridges extend onto the parietal region.
The intermediate nature of hoplomyoides argues for including the genus Hoplomys as a subgenus of Proechimys.
One subspecies in the subgenus Trinomys differs from the general characteristics of the subgenus in sometimes showing a small main fold in P4 whereas it is large in all other cheekteeth.
This arid belt probably developed relatively early, since in deposits of late Pleistocene age, remains of the subgenus Trinomys have been found in the area where the subgenus still occurs.
