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

 owing to the imperfection of Dr. Ilolbrook's description. It can be lu'st 

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

 ally of C. triseriatus. 



A small form is found in Florida, which I have descril)ed under the 

 name of Chorophilus rerrticosus. It differs somewhat liorn the typical 

 Nigricans, and I suspect that it will turn out to Ix^ a siibsjK'cies. It 

 dilfers, besides its very small size, in the somewhat loliger tarsus, wliieii 

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

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

 are as follows :

Tliis ChiMophilus is similar in proportions to the C /criarniii, but is 

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

 and the coloration. The tuber<!ular ui)per surfaee is (piite peeubar, and 

 the smooth giilar region i8e(pially wanting in the Northern frog.
