Species 4th. V, Pruinosus, Say. — Vide Long's Exp. to the 

 Rocky Mountains, Vol. 1, p. 167. 



Mr. T. Say who noticed this species, when on the exploring ex- 

 pedition under Lieut. Col. (then Major) S. H. Long, has thus 

 distinguished it : — ears broad, not so long as the head, hairy on 

 their external side, more than half their length ; auriculum, ob- 

 tuse at tip, and arcuated ; pelage, hairy above, ferruginous about 

 the sacrum, dull yellowish white on the throat : interfemoral 

 membrane covered with fur ; length, nearly four inches and a 

 half. Inhabits the western states, and western Pennsylvania. 



Species 5th. V. Arquatus, Say. — Long's Exp. ut supra. 



Head, large ; ears, rather shorter, with the posterior edge ob- 

 tusely emarginated ; auriculum arcuated ; interfemoral mem- 

 brane naked, including the tail to one half the penultimate 

 joint ; total length, five inches ; expansion of wings, thirteen in- 

 ches. Inhabits the western states. 



Species 6th. V, Subulatusy Say. — Long's Exp. Vol. 2, p. 65. 

 This species is the nearest allied to the Vespertilio Caroliniensis, 

 of Geotfroy, from which, however, it differs in colour, form of, 

 the auriculum, and in other particulars. Mr. Say observed it in 

 the distant territories. A specimen was subsequently presented 

 to the Academy of Natural Science, from the White moun- 

 tains, New Hampshire.
