Teeth. — Though in general like those of Glossophaga soridna the 

 teeth of G. longirostris present certain characters by which they may 

 be easily recognized. When viewed either from the front, from behind, 

 or on the cutting edge the outer upper incisor never appears to be 

 obviously smaller than the inner tooth, w^hile in most specimens, at 

 least when unworn, it has the greater bulk. Anterior upper pre- 

 molar very narrowly elliptical in crown outline, the width at middle 

 about one-fourth tlie length, the general form other^\dse much as in 

 (r. soridna. Posterior upper premolar with postero-internal region 

 usually much less developed than in G. soridna, so that in the majority 

 of specimens the crown outline though less narrowly elliptical does 

 not differ noticeably from that of the anterior tooth. Individuals 

 of either species may be found, however, in which the form of this 

 tooth is not diagnostic. The same narrowness of crown characterizes 

 the lower premolars as compared with those of GlossopJiaga soridna. 

 Upper molars essentially as in the related species, but lower molars 

 narrower in proportion to their length. 



Measurements. — See under subspecies. 



Remarks. — Though it does not exceed in general size the larger 

 races of Glossophaga soridna tliis animal is distiuctly larger than the 

 typical form of soridna, the only one that it is known to occur together 

 with. It appears to be less widely distributed than the related 

 species, no specimen referable to it having been seen from any other 

 region than the coast of northern South America and the adjacent 

 Lesser Antilles. As all members of the genus are easily procured 

 wherever they occur, this fact probably has more significance than 

 might otherwise be the case. The insular representative proves to 

 differ from that of the mainland by average characters only. It is 

 therefore treated as a subspecies.
