of his great toe. He made light of it and said he had often had the 
same experience. The wound healed quickly and caused only slight 
inconvenience. Later, one of our porters or cargueros was bitten on 
the same spot, the great toe, while sleeping in the open air during the 
journey from Moyobamba to Balsapuerto. 
Amorphochilus schnabli Peters. 
Two specimens, Hacienda Limon, near Balsas. 
Since the publication of the original description of this rare bat 
by Peters in 1877, no additional records of it have appeared. Its 
rarity in collections is perhaps due to its habit, as observed by us, of 
flying at an hour when humans usually are asleep. The two individuals 
obtained were taken on separate occasions but in each case the hour 
was approximately three in the morning. Happening to awaken at 
that time, we heard them flying about our room and quickly closing the 
doors made them prisoners. 
These specimens agree closely with the excellent description and 
figures published by Peters. The greatest discrepancy is in the color, 
which he gives as dark cinnamon brown. In a dry skin unaffected by 
preservative the color of the upper parts is dark smoke gray tinged with 
drab, the hairs being long (8-10 mm.), soft, and at their bases mouse 
gray. The under parts are practically the same color as the back and 
about the muzzle there is a tinge of brownish, perhaps extraneous. 
The form of the skull in general is very similar to that of Furipterus; 
braincase slightly higher and narrower but palate broader, especially 
anteriorly; rostrum slightly longer and broader with lachrymals more 
expanded. In our specimen the braincase is relatively lower than in 
the figures published by Peters. Consequently the distinction drawn 
by Miller in his key to the genera of Furipteridze! does not hold, the 
ratio between the height and length of the braincase being practically 
the same in the two genera (see measurements). The teeth show 
numerous slight departures from those of Furipterus. The outer upper 
incisor is separated from the canine by a much greater space, about 
equalling the basal length of the canine. The upper canine has its 
posterior cutting edge entire and with only slight concavity toward the 
tip; its cingulum is scarcely developed, the conspicuous anterior and 
posterior cusps of Furipterus being absent. The posterior upper pre- 
molar has only a slight indication of an inner cusp. The upper molars
