4. Chorophilus copii. 
Cystignathus ornatus, Giinth. Cat. p. 29. 
Chorophilus ocularis, Cope, Check-list N.-Amer. Rept. p. 30. 
Tongue circular, entire. Vomerine teeth in two slightly oblique 
oval groups behind the level of the choanee. Head slightly longer 
than broad; snout rounded, as long as the diameter of the orbit ; 
canthus rostralis rather indistinct ; interorbital space as broad as 
the upper eyelid ; tympanum somewhat more than half the diameter 
of the eye. Fingers and toes moderate, the tips very indistinctly 
dilated ; first finger shorter than second ; toes with a slight rudiment 
of web; subarticular tubercles small; no outer metatarsal tubercle. 
The hind limb being carried forwards along the body, the tibio- 
tarsal articulation marks the tympanum. Skin smooth above, 
granulate on the belly. Olive above ; sides with three black spots, 
viz. a streak from the eye to the shoulder, an oval spot in the middle 
of the side, and one or two smaller ones on the loin.

Mr. Cope considers this Frog specifically distinct from C. ornatus, 
and identifies it with Hyla ocularis of Daudin. The latter opinion I 
cannot share, as nothing in the French author’s description and 
figure indicates the least analogy with this form. The toes are 
represented as half webbed in H. ocularis, and the digital expansions 
of C. copw are so slight that they would certainly have escaped 
Daudin’s observation. Moreover the colour is quite different.

diameter of the eye; canthus rostralis well marked but contracted ;

the front of the orbit. Skin smooth above, granulate beneath.
