NO. 2034. BATS OF THE GENUS GL0S80PHAGA— MILLER. 415 



Diagnosis. — Glossophagine bats with: (a) thirty-four teeth 

 • 2—2 1—1 2—2 3—3 



1- 2^2' ^' TZT' P°^' qZq' ^' 5Z^^^^^' ^^^ incisors both above and 



below in unbroken series, (c) complete zygoma, and (d) short tail 

 extending barely to middle of wide uropatagium. 



Remarks. — The genus Glossophaga contains the most widely dis- 

 tributed and best-known members of the family. Though super- 

 ficially much resembled by Lichonycteris and Lonchophylla the genus 

 is at once recognizable by its technical characters. 



Key to the species and subspecies of Glossophaga. 



Outer upper incisor about equal to inner in bulk; upper premolars essentially alike 

 in crown outline when viewed from below. 



Brain case narrow and low, its dorsal profile usually not forming evident angle 



with that of rostrum in interorbital region (Curayao) elongata (p. 423). 



Brain case broad and high, its dorsal profile usually forming evident angle with 

 that of rostrum in interorbital region (Northern South America and southern 



Lesser Antilles) longirostris (p. 421). 



Width of mj about one-third length; inflation of brain case extreme (Northern 



South America) longirostris longirostris (p. 422). 



Width of mg about one-half length; inflation of brain case not extreme 



(Grenada and Grenadines) longirostris rostrata (p. 423). 



Outer upper incisor obviously less than inner in bulk; upper premolars usually 



unlike in crown outline when viewed from below soricina (p. 415). 



Length of forearm 33 to 36.6 mm.; condylobasal length of skull usually less than 

 20.6 mm. (18.6 to 21). 



Condylobasal length of skull 19.8 to 21 mm. 



(Panama to central Mexico) soricina leachii (p. 419). 



Condylobasal length of skull 18.6 to 20 mm. 



Ear from meatus 14 to 15 mm. (Brazil, eastern Peru, British Guiana, 



Venezuela, Trinidad) soricinn soricina (p. 418). 



Ear from meatus 13 to 14 mm. (Paraguay) soricina microtis (p. 419). 



Length of forearm 35.4 to 40 mm.; condylobasal length of skull usually more than 

 20.6 mm. (20.6 to 21.4). 



Brain case conspicuously inflated ; rostrum more robust (central and western 



Peru) soricina valens (p. 420). 



Brain case moderately inflated; rostrum less robust. 



Crown area of molars normal (Tres Marias Islands) .soridna mutica (p. 420) . 

 Crown area of molars slightly increased (Jamaica), soricina aniiZkr«7n(p. 420). 



GLOSSOPHAGA SORICINA (Pallas). 



(Synonymy under subspecies.) 



Geographic distribution. — Tropical America from Paraguay and 

 southern Brazil to central Mexico; also the islands of Trinidad, Ja- 

 maica, and the Tres Marias group. 



Diagnosis. — Skull usually less than 21 mm. in condylobasal length 

 (18.6 to 21.6 mm.), its rostral portion small, appearing much shorter 

 than brain case; outer upper incisor distinctly less than inner in 

 bulk; pm^ and pm* noticeably unUke in crown outline. 



Color. — General color of upper parts cinnamon (Ridgway, color
