This species is rare in collections and has not been well identified, 

 owing to the imperfection of Dr. Holbrook's description. It can be best 

 recognized from Le Conte's description above quoted. It is an evident 

 ally of C. triseriatus. 



A small form is found in Florida, which I have described under the 

 name of ClioropMlus verrucosus. It differs somewhat from the typical 

 Nigricans, and I suspect that it will turn out to be a subspecies. It 

 differs, besides its very small size, iu the somewhat longer tarsus, which 

 exceeds the foot minus the fourth toe, in length. The yellow stripe on 

 the upper lip is broken up into a series of spots. The measurements 

 are as follows :

This Chorophilus is similar in proportions to the G feriarum, but is 

 well distinguished by the characters of the longer hind leg, the skiu, 

 and the coloration. The tubercular upper surface is quite peculiar, and 

 the smooth gnlar region is equally wanting in the Northern frog.
