484 Mr. Bell on a new Species of Terrapene, 



Description, 



Size nearly that of P saris Cay anus. Crown of head and nape 

 pitch-black, space between the bill and eyes, and eye streak 

 white, tinged with red. Cheeks and ear-coverts deep reddish 

 brown. Back, rump, and wing-coverts ash-grey, the tips of some 

 of the feathers black.* Wings and tail black. Breast aud belly- 

 greyish white, under tail-coverts white. Bill blueish black, rather 

 broader than that of Psaris Cayanus, 



A specimen of this species is placed by the side of P. Cay anus 

 in the Parisian Museum, but without a ticket attached to it, 

 merely stating it to be from Pernambuco. In the valuable cabinet 

 of the Baron Laugier is another specimen, likewise unnamed. 

 This species, in its form and the distribution of its colours, is 

 nearly allied to P. Cayanus. 



In the Parisian Museum Psaris cristaius of Mr. Swainson is 

 placed at the extremity of the Thamnophili^ and ticketed Lanius 

 atricilla. Its appearance immediately arrested my attention and 

 that of a friend who accompanied me ; and I find that we consi- 

 dered it at the time as possessing the characters of a true Psaris. 

 We afterwards found it placed among that group in the Baron 

 Laugier's collection, under the title, I think, of P. atricilla. 



I am, Gentlemen, 



Yours, &c. 



P. J. Selby.
