List of specimens. 



CISTOTHORUS, Cabanis. 



Cistothorus, Cabanis, Mus. Hein. 1850-'l, 77. Type Troglodytes stellaris, 

 TeUnatodytes , Cabanis, Mus. Hein. 1850-'l, 78. Type CertUa paliistris. 

 Thriothorus, Vieillot, Analyse, 1816, according to G. R. Gray. See article on genus Thriothorus. 



Ch. — Bill about as long as the head or much shorter, much compressed, not notched, gently decurved from the middle ; the gonys 

 slightly concave or straight. Toes reaching to the end of the tail. Tarsus longer than the middle toe. Hind toe longer than 

 the lateral, shorter than the middle. Lateral toes about equal. Hind toe longer than or equal to its digit. Wings rather 

 longer than the tail, all the feathers of which are much graduated ; the lateral only two-thirds the middle. The feathers 

 narrow. Back black, conspicuously streaked with white. 



The excessive graduation of all the feathers of a tail shorter than the wings, in connexion 

 with stout feet and a hind toe as long as or longer than its digit, appears to characterize this 

 group. I have drawn the characters to include both Cistothorus and Telmatodytes of Cahanis, 

 as they are very closely related. The characters of these will be found under the suh-family 

 Troglodytinae.
