RANA MEGAPODA Taylor 
Rana megapoda Taytor, Univ. Kansas Sci. Bull., vol. 28, pt. 2, No. 14, Nov. 15, 
1942d, pp. 310-318, pl. 28, figs. 1, 2 (near Chapala, Jalisco). 
A series of eight specimens (U.S.N.M. Nos. 113998-114005) was 
collected on February 24, 1939, at La Palma, Lake Chapala, Jalisco. 
These have been made paratypes. . 
This is one of the largest species of Rana. Our largest female 
specimen measures 152 mm. from snout to vent; the largest male, 
117mm. In the past this species has been confused with Rana monte- 
zumae, which occurs in the same general region. 
The specimens were found at night in Lake Chapala near a pier of 
loose rocks, into which several others took refuge and escaped.
