. Bulletin - United States National Museum. Science. 186 BULLETIN 57, UNTTED STATES NATIONAL MUSEUM. CJiaracters.—Differs extermilly from its allies in the much shorter leg, proportionally about as long as in the small species of J/i/otis, and in the nearly unmodified ear, the anterior border of which arises directly above eye, the posterior border behind base of tragus, so that the peculiar funnel-like form characteristic of the other genera is scarcely indicated. Skull (fig. 28) differing from that of the allied genera in the low braincase and very large rostrum, the length of which, as in ChUotiatalus^ is fully equal to that of braincase, the breadth of palate including third molars equal to that above posterior roots of zygomata. Maxillaries swollen, but nnicli less than in Pho- (Jof&s, not enough to conceal molars when skull is viewed from above. Teeth not essentially different from those of Xdtahix, but canine and anterior premolar both above and below greatly reduced in si/e, the canine scarcely liigher than its corresponding large premolar, and the first upper jiremolar scarcely as large as outer incisor. Lower premolars nuu-h less trenchant than in Naffdiis^ tlie shafts almost terete, though retaining distinct traces of the cutting edges; pm,.-. much reduced in size, its height scarcely half that of pm 3. Species examined.—Nyctiellus lepklus (Gervais). Remarks.—As compared with other mem- bers of its sul)family, Nyetiellns is distinctly less specialized externally; but in the peculiar form of the skull and in the reduced size of the anterior canine and j^remolar it repre- sents a more advanced stage than any of the related genera, both of these characters suggesting the members of the next family.
