ill the middle, and dark at tlie extreme tips. This is exactly what 

 Cuvier describes as tlie character of the fur of his 'Bloudin' {P.suhjiavas). 



Subulatus (Vespertilio). Say, in Long's Exped. to Kocky Mts., II, p. 65 

 footnote, 1823. The original description of Yesjyertilio subulatus leaves 

 the species undeterminable. It is as follows: 



Ears longer than 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; tragus elongated, 

 snbulate; the hair above blackish at base, tij) dnll cinereous; the interfermoral 

 membrane hairy at base, the hairs nniooloured, and a few also scattered over its sur- 

 face, 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 seta> extending over the 

 nails; only a minnte portion of the tail protrudes beyond the membrane. Total 

 length, 2,^0 -inches. Tail, 11 inches. 



While there is nothing in this account that refers unquestionably to 

 the longer eared of the two species of Myotis inhabiting the eastern 

 United States, the name has passed current for this animal so long that, 

 after careful consideration of all the evidence, I am unwilling to substi- 

 tute for it Trouessart's na,i\m septeutrioualis, the only one unequivocally 

 based on the species. Say's Vespertilio subulatus came from the Arkan- 

 sas Elver, near the present town of La Junta, Colorado. The bats of this 

 region are not well known, but at present Myotis evotis^ M. californicus 

 ciliolabrumj and AI. lucifugus longicrus are the only members of the 

 genus Myotis which may confidently be expected to occur there. From 

 the knowm range of Myotis subulatus to the north and west, however, 

 its regular occurrence in Colorado is by no means impossible. . Ai)par- 

 ently Le Conte Avas the first subsequent writer to define the name 

 suMdatuSj and, as has already been shown, his animal was an individual 

 variation of tlie shorter eared of the two eastern species. If this deter- 

 mination be taken as final, there can be no question as to the necessity 

 of adopting the name septentrionalis for the longer eared animal, but at 

 inesent the power of the 'first reviser' is so nutch in question that too 

 much should not be staked on it. Harrison Allen, in 1804, ai)plied the 

 name subulatus to the longer eared of the two forms, and in this sense 

 it passed unchallenged until 1893, when the same author united the 

 lucifugus and subulatus of his earlier monograph under the specific 

 name gryphus. This change has not been generally adopted, so that in 

 retaining the specific name subulatus^ I am merely continuing the usage 

 of the past thirty-four years, not, however, without grave misgivings 

 that the reasons for so doing are in reality unsound. 



Teliotis (Atalapha). H. Allen, Proc. Amer. Philos. Soc, XXIX, p. 1, 

 February 11, 1891. Atalapha teliotis H. Allen is the only name based 

 on the Californian form of Lasiurus borealis. 



Teiiuidorsalis (Vespertilio). II. Allen, Proc. Acad. Xat. Sci. Pliila., p. 

 283, 1866. This is a synonym of Myotis californicus based on a speci- 

 men (Xo. 5533, U. S. Xat. Mus.) from Cape St. Lucas, Lower California. 



Tesselatus (Vespertilio). Rafinesque, Anierican Monthly Mag., Ill, 

 p. 145, 1818. Rafinesque's Vespertilio tesselatus is Lasiurus borealis 

 (Miiller). The original description is as follows : 



Tail half of total length, hairy above, npper incisores 2, remote, lower 6, body 

 fallow above, head pale, dirty fulvous beneath, with a faint fallow collar, with 2
