SCOTOPHILUS. 45 



A bat, labelled 5345, Cass Co., Mo., presented by Dr. P. R. 

 Hoy, presents peculiarities so marked that it cannot be assigned 

 to any of the foregoing species. It belongs, however, to the 

 group characterized by the small and equal superior incisors, of 

 which ;S. georgianus and S. liesperus are the representatives. 

 Indeed, the dentition throughout is similar to that seen in ^5. 

 georgianus ; and the tout ensemble of the animal indicates that it 

 has a closer affinity to the former than to the latter of these species. 



The head is flat and broad ; lips slightly tumid ; nostrils open- 

 ing sublaterally, placed near the lip ; the snout rather thick, and 

 scarcely if at all emarginated ; auricles of a light brown color, 

 not quite as long as head, subulate, tip turned slightly outwards ; 

 internal basal border not bluntish and rounded as in other species 

 of Scotophilus, but markedly and sharply p)roduced, as in Ves- 

 2)ertilio. Tragus similar to that- of S. georgianus, short, stout; 

 outer border strongly convex. Wing membrane of a blackish- 

 brown color, attached to base of toes ; foot rather large. Inter- 

 femoral membrane ample. Termination of calcaneum not abrupt 

 Tip of tail exserted, half the length of terminal caudal segment. 

 Color very similar to that of V. subulalus — the fur of the back 

 being more olive. 



The above brief description agrees with that of S. georgianus, 

 on the one hand, in the dentition, shape of tragus and style of 

 wing membrane ; with that of V. subulalus, on the other, in the 

 shape of auricle, and in the coloring of the fur. 



I have deemed it sufficient to thus indicate the peculiarities of 

 this individual, without venturing upon a specific name, preferring 

 to await the receipt of additional specimens.
