_Remarks._--The specimen from thirty kilometers south-southeast of Jesus Carranza, Veracruz, and the three specimens from Honduras agree in all respects with topotypes. The color of _P. s. veracrucis_ is much darker than that of _P. s. obscurus_ and is between black and the darkest brown in Ridgway's (_op. cit._) color key. Rinker (Jour. Mamm., 29:179-180,1948) described the three specimens from Honduras without assigning a specific name to them because he lacked topotypes of _P. s. veracrucis_. We find nothing in his description to correct, but can add that the upper tooth-rows in many, but not in all, specimens of _P. s. veracrucis_ are straighter than in _P. s. subflavus_. Probably it was this feature to which Rinker referred when he said that in _veracrucis_ "The tooth rows tend to be more convergent posteriorly." Rinker did not refer the three specimens from Honduras to _P. veracrucis_ because Ward's original description states that _veracrucis_ has evenly spaced lower incisors and a basal cusp on the lower canine on only its forward edge. Rinker's specimens from Honduras have the first incisors in contact with each other, the second incisors in contact with the first incisors and the third incisor on each side of the lower jaw separated by a space from the second incisor and from the canine. The specimens from Honduras have a basal cusp on the hinder edge of the lower canine. In these two features they agree with the specimens from Veracruz and with specimens of _Pipistrellus subflavus_ from the United States and Canada. It is clear that Ward (Amer. Nat., 25:747,1891) was mistaken in stating that the lower incisors of _veracrucis_ were evenly spaced and that the canine had a basal cusp on only the forward edge. Ward (_loc. cit._) was correct in regarding his _Vesperugo veracrucis_ as "most closely related to _V. georgianus_ [= _Pipistrellus subflavus_]," but for want of actual specimens of _P. subflavus_ to use in comparison was incorrect in supposing that _P. subflavus_ had only two bands of color on the fur, more hair on the legs, and a larger area of hair on the interfemoral membrane. In these respects we perceive no difference between specimens from Veracruz and the United States. _Vesperugo veracrucis_ Ward, therefore, proves to be only a subspecies of _Pipistrellus subflavus_, but is well characterized by dark color and small size. _University of Kansas Museum of Natural History, Lawrence, Kansas._ _Transmitted October 31, 1949._ [] 23-1546 * * * * * Transcriber's Notes The text presented in this file is that contained in the original printed version.
