nariensis in the Zoology of the voyage of the Coquille agree? very well ; but the 

 figure of the animal which accompanies it is so wretchedly executed, as to be 

 of no use in determining the point. 



V. cinereus. Palisot de B(;auvois, 1. c. V. pruinosus Say, Long's Expe- 

 dition vol. i. p. 168. 



Dentition the same in every respect as in V. noveboracensis. Hair above 

 four-colored, that is to say, black at the base, then reddish-brown, afterwards 

 black, and tipped with white: beneath two-colored, the lower half dark cine- 

 reous, the upper yellowish or grey, so that the pelage of the animal appears on 

 the upper side, variegated with reddish brown and black, and powdered over 

 with white, this latter color so disposed as to form transverse curved and wa- 

 ving lines, on the under side, yellowish grey on the sides and cinereous mixed 

 with grey on the other parts. Head above and throat yellowish grey; face 

 hairy ; chin very dark brown : nose flat, blunt, emarginate. Ears black, sim- 

 ple round, densely covered both within and without on the anterior portion, with 

 short yellowish grey hair, leaving a distinct narrow, naked margin. Orillon 

 cultriform, blunt and sparsely hairy, half the length of the ear. Membrane 

 dusky, for one third its breadth along the arm brown ; sometimes beyond this 

 spotted with brown, very much so near the body. A portion next the body in 

 a straight line from the shoulder to the feet is hairy. There is generally a 

 small white hairy spot at the anterior joint of the humerus (sometimes how- 

 ever the hairs are pale brown, not white), and another at the base of the thumb. 

 The membrane beneath is hairy as far as the third finger for nearly half its 

 breadth, this hairy space joins another of the same width along the sides, and 

 there is generally a large white spot at the axilla or insertion of the humerus. In- 

 terfemoral including the whole of the tail, above densely hairy, beneath only 

 at the base, forming a roundish deeply emarginate patch, feet black, sparingly 

 hairy. 



Length 3 inches. Tail 2-1. Extent 16-8. Head -94. Ear -48. Orillor, .25. 



I have given to this species the name imposed upon it by Palisot de Beauvois, 

 ann. 1796 in the catalogue of Peale's Museum, although I am not certain that 

 it differs from the V. lasiurus of Linnaeus. This last is said by Temminck to 

 inhabit Cayenne and North America. The description of Temminck suits our 

 animal very well, but whether the two are the same, remains yet to be deter- 

 mined. The figure in Schreber is undoubtedly taken from a V. noveboracensis 

 The V. bonarien3is described and figured by Lesson in the Zoology of the voy- 

 age of the Coquille vol. i. p. 137 tab. 62, may be either the one or the other, 

 the figure is so excessively bad that nothing can be made of it. This is the 

 largest of all the bats found in the United States, it is not common, and is seen 

 more frequently in the middle than in the northern or southern states. 



I have never had it in my power to examine more than six or seven individ- 

 uals of this species, and therefore cannot say how far the colors may vary. 



V CREPCSCULARIS. 



Dentition the same as in the two former species. 



Hair black, above tipped with chestnut brown, beneath with paler or cinereous 

 brown more or less distinctly varied by the black of the lower part of the hair. 

 Head rather depressed, face flat, black, naked, with a few scattered, long, coarse 

 hairs, and a small wart over each eye ; nose broad, flat, blunt, emarginate ; chin 

 with a small double wart on the lower part. Ears shorter than the head, tri- 

 angularly ovate, rounded at the point, slightly emarginate on the hinder edge, 

 dusky, naked. Orillon short, dolabriform, blunt. Membrane very thin, dusky, 

 naked except a narrow space next the body. Interfemoral including the tail 

 except the two last joints naked, except a small portion of the base which both 

 above and beneath is slightly bjairy. 



Length 2-2. Tail 1-4, naked part -15. Extent 10-5. Head *7. Ears -3. Oril- 

 lon -19. 



Inhabits Georgia. 



This is the V. creeks of F. Cuvier, this name however being unmeaning and
