There seems to be no good reason for applyino; a trinominal to 

 this eastern representative of Rami esculenta. The character of the 

 niinierous short dermal ridges on the back between the dorso-lateral 

 folds seems absolutely diagnostic. Moreover, in proportions it 

 differs more from its nearest neighbor, Rana ridihunda, than from 

 the more remote forms of R. esculenta inasmuch as the heels do 

 not overlap. Finally, it has not been shown as yet that the range 

 of our species meets that of any of the western forms. 



The types of R. riigromaculata of Ilallowell (collected by Doctor 

 Morrow) are not in the National Museum, but the description fits our 

 species fairly well. The types of his R. tnarmorata, however, are still

in good state of preservation (U.S.N.M. No. 12159), being apparently 

 two females very much like the specimen figured by Schlegel (],. c.) as 

 R. esculenta. « Hallo well's measurements were apparently taken (in a 

 rather careless manner) from the smaller specimen. It is worthy of 

 note that Hallowell referred several other specimens, males with large 

 vocal vesicles (U.S.N.M. No. 7415, figs. 76-80), to Rana rugosa, thus 

 enumerating the specimens of the same species, and practically from 

 the same locality, under three different specific names.
