108 CYSTIGNATHUS NIGRITUS. 



spots and transverse bars of black, and dusky yellowish-white below; there are 

 four long and dehcate fingers. The posterior extremities are very long, and 

 coloured both above and below, like the anterior; there are five toes, not 

 palmated. 



Dimensions. Length, 1 inch 6 lines; of thigh, 8 lines; of leg, 85 lines; tarsus 

 and toes, 10 lines. 



, Habits. But little is known of the habits of the Cystignathus nigritus; but, 

 from the form of the posterior extremities and the arrangement of its toes, it 

 would seem to be a land animal, and closely allied with the Cystignathus ornatus. 



Geographical Distribution. This animal has as yet only been found in 

 Georgia and Carolina; Leconte observed it in the former state, and I have seen it 

 in the latter. 



General Remarks. Leconte gave the specific name nigrita to this animal in 

 his "Remarks on the genus Hyla and Rana;"* and although he does not describe 

 it in detail, yet the characters he assigns are sufficient at all times to distinguish 

 this frog from all others, consequently his name must be retained.
