296 PROCEEDINGS OF THE ACADEMY OF [April, 



from Mirador, Mexico, with the throat folds greatly developed 

 caused Dr. Harrison Alien to describe the subgenus Trichocoryes 

 and the sjiecies mcmurtrii, which he placed therein/ A specimen 

 of C. mexicanus from the same locality accompanied the one 

 described. Alston mentions' that Dr. Peters had informed him 

 that the Berlin ^Museum possessed a specimen of C. mcmurtra as 

 well as one of C. senex. 



The only remaining published record of specimens of this genus 

 is that of one female from Cerro de los Pajeros, Las Vegas, Vera 

 Cruz, Mexico, which was described by ]Mr. Henry L. "Ward as a 

 new species, Centurio minor.* 



General Relations. — A very superficial examination of a speci- 

 men of Centurio reveals the gap which exists between it and the 

 other genera of the subfamily in which it has previously been 

 placed. Of the genera of the Stenodermatince I have examined 

 all but two, i.e., Ametrida and Ectophylla, and the resulting belief 

 is that Centurio should stand apart. The singular facial structure, 

 throat folds, absence of true nose-leaf, and peculiar canines all 

 present an individuality not shared by the other genera, 



Accordingly I propose to separate Centurio as a new subfamily, 

 the differential characters of which would be as follows : 



CENTURIONINiE. 



Rnstral portion of skull very 

 broad. 



STENODERMATJX.E. 



Rostral portion of skull not very 



broad (except in Sjyhceronyc- 



teris and probably Ametrida). 



Upper canines without anterior i Upper canines with anterior 



basal concavity. basal concavity. 



Face with distinct nose-leaf. Face without distinct nose-leaf, 



. and without distinct cutaneous i and with distinct cutaneous 



facial ornaments (except in facial ornaments (nostrils not 



Sphceronyderis^. j opening directly upon the sur- 



I face). 



Upper lip not emarginate. Upper lip centrally emarginate. 



Ears without additional lobe on Ears with additional lobe on the 



the internal margin. internal margin. 



Throat without transverse folds Throat with transverse folds of
