108 CYSTIGNATHUS NIGRITUS. 
spots and transverse bars of black, and dusky yellowish-white below; there are 
four long and delicate fingers. The posterior extremities are very long, and 
coloured both above and below, like the anterior; there are five toes, not 
palmated. 
Divensions. Length, 1 inch 6 lines; of thigh, 8 lines; of leg, 83 lines; tarsus 
and toes, 10 lines. 
Hasits. 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. 
GeocrapruicaL Distrrisution. 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. 
Generat 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.
