as Jamaica, the Tres Marias Islands, and northern Peru. While 

 there is no difficulty in distinguishing each large form from its geo- 

 graphically nearest small form, the characters of the large races as 

 compared with each other are so slight that if all the known speci- 

 mens of the three were mixed together without labels they would 

 not appear to make an unusually variable form. On close study 

 slight average characters can be detected, and in view of the obvi- 

 ously independent origins of the three it seems best to recognize 

 each as a distinct race.

Type-locality. — Dutch Guiana. No locality is mentioned in the 

 first account of the species. In the Spicilegia (p. 24) Pallas says that 

 he has seen specimens from Surinam and the Caribbean Islands.^ 

 I have therefore chosen Dutch Guiana as the type locality.'' Type 

 specimen probably lost.^ 



Geographic distribution. — Tropical America from southern Brazil 

 to Trinidad and the coast of Colombia; west to eastern Peru. 



Diagnosis. — Size minimum for the genus (forearm, 33 to 37 mm.; 

 condylobasal length of skull, 18.6 to 19.8 mm.); ear normal, its 

 height from meatus, 14 to 15 mm. 



Measurements. — For detailed measurements see table, page 425. 



Specimens examined. — Eighty-three, from the following localities : 



Brazil— -Sao Paulo: San Sebastiao, 4 skins (U.S.N.M. and Field). 

 Goyaz: Baiao, Rio Tocantins, 1 skin (Field) ; Catema, Rio Tocantins, 

 1 skin (Field). Maranhao: Maranhao City, 3. Brazilian Guiana: 

 Faro, Rio Jamunda, 2 skins (Field). 



Peru — Loreto: Moyobamba, 16 (5 skins). Field.
