Type-locality. — Not known. The type-.speciiiien," a young female, 

 is in the British Museum of Natural Histor}^, Lidth de Jeude collec- 

 tion, and is probably from northern South America. 



Geographic distrilnition. — Prol)ably the whole of tropical and sub- 

 tropical South America, Trinidad, the Lesser and perhaps the Greater 

 Antilles. The southern limit of its range, so far as known, is Sapu- 

 cay, Paragua3\ The species has been taken at sea level within two 

 degrees of the equator and at an elevation of 3,500 feet in the same 

 latitude. The northern limit may be considered to be Panama, where 

 it begins to intergrade with the subspecies astecum. 



Characters. — Size, intermediate between //. 2>- aztecuni and II. suh- 

 rufum.^ nearest the former; external edge of maxillary tooth-row only 

 slightly concave (never with an angular curve); teeth moderately 

 heavy; mandiVjles and mandil)ular teeth light. 



Pelage. — The character of the pelage, as well as its color, is ex- 

 tremely variable. In general the color is darker than in any other 

 form of the genus, and fewer individuals in the red phase are to be 

 found, while none that 1 have seen have the bright ferruginous tinge 

 observable in some of the specimens of aztecum. Ilemiderina tricolor 

 was founded on specimens from Paraguay "similar to Hemiderma 

 pe7'spicillata,iii, but with fur longer and more silky in texture and the 

 three color-bands on the hairs of the back strongl}^ contrasted.""'' 

 These characters, however, do not prove to be distinctive, as the type 

 of H. tricolor can be almost exactly matched by specimens at hand 

 from Brazil, Trinidad, and Costa Rica, while two skins from Paraguay 

 have short fur, reddish in color, and without strongly contrasted color- 

 bands. 



Fur a7id rnemhranes. — Membranes blackish in color; interfemoral 

 membrane sparsely furred at the base above and below, with a few 



«Mr. Gerritt S. Miller, jr., has recently examined the type and made the follow- 

 ing notes upon it: Female, not fidly adult. Finger-joints not perfect, but milk- 

 dentition all gone. Head and body, 65 nun.; tibia, 17; foot, 11.5; forearm, 39.4; 

 third finger, 82; ear, from crown, 13.4; thuml), 11.4.
