Remarks. — In this species there is considerable geographic and 

 individual variation in color, size, and proportions. Generic dis- 

 tinction of the small fish-eating bat from the larger, typical form of 

 the genus is not indicated, and the name Dirias should be discarded 

 even as a subgenus. 



The earliest published specific name for the small Noctilio is 

 Vespertilio lahialis Kerr (Animal Kingdom, p. 93, 1792). Kerr's 

 description of lahialis is based on Pennant's Peruvian bat variety j8 

 (Syn. Quad., p. 365, 1771). According to Pennant (and Kerr) the 

 species "inhabits Peru and the Mosquito shore," eastern Nicaragua.
