 of the other species, those of the Edible Frog being propor-

I think there can be no doubt that the present species is 

 distinct from the Common Frog, and that it is certainly not 

 R. esculenta. I am not aware of any other species to which 

 it can be referred, and I have therefore assigned to it the 

 specific name Scotica provisionally. In order, however, to 

 afford an opportunity to Scottish naturalists of comparing 

 perfect and recent specimens with a correct representation of 

 R. esculenta, I give a figure of the latter species from one of 

 the specimens sent to me by M. Bibron.
