hence seems not improbable that M. boucourtiatms, from Vera 

 Paz, based mainly on this last feature, may be referable to M. 

 mexicanus. 



22. Sturnira lilium (E. Geofr.). One specimen, Sierra 

 Nevada de Colima, Jalisco, Dec. 6, 1889. 



This is apparently the first record for this species from any 

 point north of Honduras and Costa Rica.

Two specimens, male adult in alcohol, and female adult, skin, 

 Santo Domingo, Tehuantepec, May, 1890. (For remarks on these 

 specimens see this Bulletin, antea, pp. 170-172.)

Two skins with skulls and one additional skull, Sarabia, Tehu- 

 antepec, Mexico, April 19, 1890. 



These are very red examples of this form, the whole ventral 

 surface being not only deep orange red, but the same color 

 extends high up on the sides of the body and across the shoulders, 

 so as to occupy the whole thoracic region from the nape to beyond 

 the scapulae, and including also both fore and hind limbs, except 

 the feet, which are dark gray more or less mixed with dark red. 

 The rest of the dorsal surface is varied with dark rufous, black, 

 and white, the hairs being tipped with white, then ringed narrowly 

 with black, and then broadly banded with deep chestnut red. 



In Mr. Sennett's six specimens from near Tampico, to which

 of the dorsal surface are much more broadly tipped with white 

 and the red of the ventral surface, while extending far up over 

 the shoulders and covering the fore limbs, scarcely reaches the 

 median dorsal line. It is worthy of note that Mr. Sennett's
