Frogs of the Genus Rana. 417 
referred this frog to R. pustulosa, Blgr., from which it differs 
by the more broadly webbed ‘toes and the absence of a dorso- 
lateral glandular fold. The larger eye, the more oblique 
loreal region, the more distinct tympanum, the shorter tibia, 
and the absence of vocal sacs distinguish it from R. boylit, 
Baird.
