brain case, (10.5) 10.3-10.7; maxillary tooth row, (6.9) 6.5-7.0; \Nadth 

 across bases of incisors, (6.0) 6.0-6.8. 



Remarks. — The genus Sturnira is represented in Colombia by at 

 least two well-defined species. The first, S. lilium, is characterized 

 by its comparatively short rostrum, short forearm (40.44 mm. in 12 

 topo types from Paraguay), trilobate lower incisors with the middle 

 lobe nearly as large as the outer ones, paraconids, metaconids, and 

 entoconids of first two lower molars distinct and separated by deep 

 valleys, upper molar row symmetrically curved (compare Miller, 

 U. S. Nat. Mus. Bull. 57, pi. 4, fig. 3, 1907). The second, Sturnira 

 ludovici, resembles S. lilium externally and in shape of skull but 

 averages larger, lower incisors deeply bilobate in young individuals, 

 simple or weakly bilobate, often with a minute middle lobe, in fully 

 adult specimens; paraconids and metaconids of first two lower molars 

 low, poorly defined, the entoconids suppressed with no division be- 

 tween them and the metaconids, the median longitudinal groove of 

 these molars not so well defined as in S. lilium, the second upper molar 

 turned inward and not in line with the first molar. 



The range of Sturnira ludovici encompasses and exceeds that of 

 S. lilium parvidens. The present series of ludovici was taken in the 

 same locality as were two specimens of S. lilium parvidens. Two 

 skulls from Mirador, Mexico, in the United States National Museum 

 collection represent ludovici, and another skull from the same locaHty 

 is referable to S. lilium parvidens. Sturnira hondurensis Goodwin, 

 described from Honduras and recorded from Costa Rica, Sturnira 

 lilium bogotensis Shamel from Bogota, and, in the collection of the 

 Chicago Natural History Museum, 12 specimens from western Ecuador 

 and one from San Esteban, Venezuela, are all referable to S. ludovici. 



Another species nearly related to Sturnira ludovici has been de- 

 scribed from Costa Rica as Sturnirops mordax Goodwin (Amer. Mus. 

 Nov. No. 976, p. 1,1938). Except for its long rostrum with the attendant 

 greater curvature of the maxillary tooth row and the attenuation of 

 the mandibles, S. mordax is practically indistinguishable from ludovici 

 in external, cranial, and dental characters. Full generic separation 

 of mordax from Sturnira lilium is hardly advised in view of the close 

 relationship to the amiectant S. ludovici.
