Chorophilus nigritus. Proc. Acad. Nat. Sci., Phil., 1855, p. 427, Holbrook’s N. Am., 
Herp. IV, p. 107. This animal, which I had supposed to be a Southern species, limited 
to South Carolina and Georgia, is recorded by Giixther, Cat. British Museum, p. 97, 
under the name of Pseudacris nigrita, as coming from the Great Bear Lake. Should this 
species be found to have so wide a range, it will doubtless yet be found in our limits.
