Townsendi (Plecotus). Cooper, Ann. Lyceum Nat. Hist. New York, IV, 

 p. 73, 1837. Plecotus toivnsendl Cooper is the only name based on the 

 form of Gorynorhinus inhabiting the northwestern United States. 



Tumida (Rhogeessa). II. Allen, Proc. Acad. Nat. Sci. Phila., p. 286, 

 1866. Bhogeessa tumida H. Allen is tlie only name based on the small 

 Mexican bat to which it is now applied. 



Ursinus (Vespertilio). Temminck, Monographies de Mammalogie, II 

 (13« Monogr.), p. 235, 1835-41. The description of Temminck's Vesper- 

 tilio ursinus refers without nuich question to Vespertilio fuscus Beauv., 

 though the statement is made that there is no false molar in the upper 

 jaw. Color, size, and external characters, however, agree with T". f uscus. 



Velifer (Vespertilio). J. A. Allen, Bull. Am. Mus. Nat. Hist., New 

 York, III, p. 177, 1890. The name Vespertilio velifer has been applied 

 by I3r. J. A. Allen to a large species oX My oils occurring in Mexico and 

 the southwestern United Stales. The animal is closely related to the 

 Vespertilio albescens of Dobson and may eventually prove to be the same 

 as V. albescens Geoff roy. 



Velox (Nyctitherium). Marsh, Am. Journ. Sci. & Arts, 3d ser., IV, 

 p. 127, 1872. Nyctitherium velox is a fossil bat from the Eocene or 

 loAver Miocene near Henry Fork, Wyoming. 



Veraecrucis (Vesperugo). Ward, .Vinerican Naturalist, XXY, j). 745, 

 August, 1891. Vesperugo verwcrucis Ward is the only name based on 

 a form of Pipistrellus occurring in sonthern Mexico. 



Virginianus (Vespertilio). And. & Bach., Journ. Acad. Nat. Sci. Phila., 

 I, No. 7, p. 93, October, 1841. Vespertilio rirgiiiianus can not be 

 identified with any degree of certainty, though it is without nmch 

 doubt one of the small si)ecies of Myotis. The original desci'iption is 

 as follows : 



Vespertilio virf/iniauus (Virginian bat). — V. vespertilioue monticola p.inlnlnm lon- 

 gior, anricnlus i>anlnluni longioribus magisqnc acutis; dentibus primorilnis maxilhTB 

 snperioris simplicibns ; iuterfenioral i juembrana niida ; corj)ore supra fnligineo-fnsco ; 

 snbtns cinereo-fnscato. 



Virginian hat. — A little larf^er than the Monntain Bat ; ears a little longer and more 

 pointed ; upper fore teeth simple ; interfenioral membrane naked ; sooty brown above, 

 ash brown beneath. 



9_2 1-1 



Dentition. — Incisors Canines 



6 1-1 



In size this species is intermediate 1)etween F. carolinensis and V. suhnlaius. The eai' 

 is naked, less rounde.'l, and more pointed than either of the other closely allied species. 

 The tragus is very narrow, linear, and less than halt' the length of the ear. The tail 

 is inclosed in the interfenioral membrane, except the penultimate joint, which is free. 

 The anterior ui>per fore teeth, instead of being sub simple, as in the V. caroUnensis, 

 or bilobate, as in V. snhidatas and V. monlaniis, are simple. 



Color. — The nose, upper lip and upper jaw are black; wings dark brown. The 

 back is sooty bro^v^l; on each shoulder, at the insertion of the wing, there is a cir- 

 cular black spot about 4 lines in diameter ; on the under surface cinerious brown.
