CISTOTHORUS, Cabanis. 
Cistothorus , Cabanis, Mus. Hein. 1850—’1, 77. Type Troglodytes stellaris. 
Telmatodytes, Cabanis, Mas. Hein. 1850-’l, 78. Type Certhiapalustris. 
Thriothorus, Vieillot, Analyse, 1816, according to G. R. Gray. See article on genus Thriothorws. 
Cii.—B ill about as long as the head or much shorter, much compressed, not notched, gently decurved from the middle ; thegonys 
slightly concavo 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 Cabanis, 
as they are very closely related. The characters of these will be found under the sub-family 
Troglodytinae.
