Skull (fig. 26) with globular braincase rising abruptly above level of narrow, elongate rostrum. Greatest breadth of braincase about equal to depth, including audital bulla; rostrum about three-fourths as long as brain- case, its width in lachrymal region about twice depth, its lateral walls thin and translucent, but not inflated. Anterior edge of orbit over middle of second molar. Antorbital canal very long, its anterior ori- fice over middle premolar, its posterior orifice occupying entire ante- rior wall of orbit, including region in which lachrymal foramen usually occurs. Base of braincase parallel with palate. Audital bul- la? well developed, but small, covering about half surface of cochlea?. Externally characterized by the very long leg and tail, each of which exceeds the head and body in length, the large, funnel-formed ear (outer base slightly in front of inner), with thickened, dis- torted tragus, and the long muzzle with simple lips and chin; nostrils simple, di- rected outward and slightly downward. Species examined.âI have examined the three known forms. Genus PHODOTES Miller. 1906. Phodotes Miller, Proc. Biol. Soc. Washington, XIX, p. 85. June 4, 1906. Type - species.âNatalus tumidirostris Miller. Geographic distribution. â Island of Curacao, off coast of Venezuela. Number of forms.âOnly the type species is now known. Characters.âLike Natalus, but maxillaries conspicuously inflated and translucent, the swollen region extending from orbit to nares and projecting so far laterally that the molar teeth are hidden when skull is viewed from above. Species examined.âPhodotes tumidirostris (Miller). Remarks.âThe inflated, semitransparent maxillaries of the type species give the skull of Phodotes a very distinct aspect from that of Natal
