called Padoucas have been often represented as residing in 

 the district now under consideration, but are not at this 

 time to be found here, unless this name be synonymous 

 with that of the Bald-heads or some other of the six nations 

 already enumerated. 



On the morning of the 22nd, one of two hunters, who 

 had been sent out on the preceding day, but had not return- 

 ed, came into camp to give notice that a bison had been 

 killed at the distance of eight miles on the other side of the 

 river. Men were accordingly despatched with pack-horses 

 to bring in the meat. Astronomical observations were re- 

 sumed, and all the party were busily employed in the dis- 

 charge of their ordinary duties, or in preparations for the 

 approaching separation.* A vocabulary of the Kaskaia lan- 



* The New-York bat, (Vespertilio Novaboracensis. ) which occurs here, 

 does not vary in any degree from the general characters and appearance, 

 of individuals of the Atlantic states. The specimen we obtained, is most 

 unequivocally furnished with incissores in the superior jaw, which by Pen- 

 nant were denied to exist in the species of this name. These teeth being 

 small, and hardly rising' to a level with the line of the intervening callosity, 

 might be readily overlooked by a casual observer, who does not aid his 

 vision by the use of the lens. In adducing this fact, it must not be under- 

 stood that we affirm the existence of those teeth in individuals of this spe- 

 cies generally, we only refer to the single specimen before us. 



A small bat was shot this evening, during the twilight, as it flew rapidly 

 in various directions, over the surface of the creek. It appears to be an 

 immature specimen, as the molares are remarkably long and acute; the 

 canines are very much incurved, and the right inferior one is singularly 

 bifid at tip, the divisions resembling short bristles. This species is beyond 

 a doubt distinct from the Carolina bat (V. Caroliniana, Geoff.) with which 

 the ears are proportionally equally elongated, and, as in that bat, a liltle 

 ventricose on the anterior edge, so as almost to extend over the eye, but 

 the tragus is much longer, narrower, and more acute, resembling that of 

 the V. eviatginatus, Geoff., as well in form as in proportion to the length 

 of the ear. We call it V. subulntus, and it may be thus described. — Ears 

 longer th?n broad, nearly as long as the head, hairy on the basal half, a 

 little ventricose on the anterior edge, and extending near to the eye; tra- 

 gus elongated, subulate; the hair above blackish at base, tip dull cinere- 

 ous; the interfemoral membrane hairy at base, the hairs unicoloured, 

 and a few also scattered over its surface, and along its edge, as well as 

 that of the brachial membrane; hair beneath black, the tip yellowish- 

 white; hind feet rather long, a few seise extending over the nails; only ?. 

 minute portion of the tail protrudes beyond the membrane. 



Total length, ... 2 9-10 inches. 



Tail, 11-5
