CORYNORHINUS PHYLLOTIS, sp. nov. 



Leaf-eared Bat. 

 Plecotus ouritus J. A. Allen, Bull. M. C. Z., 1881, 8, p. 184 (not of Linne, 1758). 



Tijpe.— Skin and skull 5943, M. C. Z., collected by Dr. Edward 

 Palmer, 24 March, 1878. 



Type Locality. — Mexico: San Luis Potosi (probably near the city 

 of the same name). 



Distribution. — At present known from the type locality only. 



General Characters. — Ears larger than in megalotis, the transverse 

 ribs on the middle third of the outer edge subdividing and extending 

 quite to the border; skull larger, the braincase inflated, and a distinct 

 lachrymal ridge present; tips of hairs in sharp contrast with the dark 

 bases; upper surface tawny olive; calcaneum with a well-developed 

 keel. 



Color. — Hair above long and silky; basal half dark, ' fuscous black,' 

 the tips pale ' tawny olive ' ; a band of downy hair at the posterior base 

 of the ears whitish. Below, the basal two thirds of the hairs is 'fus- 

 cous black,' the tips white, washed with 'pale ochraceous buff.' The 

 distinct olive tone above is in marked contrast with the buffy or dark 

 fur of the viacrotis and megalotis coloration. 



Skull. — This species is at once distinguished from the other species 

 of the genus by its larger and differently shaped skull (Plate 1, fig. 6). 



The braincase is flattened and broad, the rostrum broader and 

 sharply depressed, with a more marked excavation medially ; there is a 

 distinct lachrymal ridge, as in Plecotus; the audital bullae are also 

 larger. The teeth differ mainly in their stouter proportions, but the 

 two upper incisors instead of being nearly side by side are one behind 

 the other in the line of the tooth-row; there is also a greater disparity 

 in size between the two anterior lower premolars, the first of which is 

 much larger, in lateral view, than the second.
