List of specimens. 



CISTOTHORUS, Cabanis. 



Cistolhorus, Cabanis, Mus. Hein. 1850-'!, 77. Type Troglodytes stellarist 

 Tehnalodytes , Cabanis, Mus. Hein. 1850-'J, 78. Type Certhia palustris. 

 TliTwlhorus, ViEiLLOT, Analyse, 1816, according to G. R. Gray. See article on genus Tliriothorus. 



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

 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 Cistotliorus and Telmatot^gtes of Cabanis, 

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

 Trocjlodytinae.
