CINCLOCERTHIA RUFICAUDA PAVIDA Ridgway. 

 ST. CHRISTOPHER TREMBLER. 



Similar in coloration to O. r. rujlcaudu, but much larger (size of 

 C. r. tremula). 



Adult male.— Length (skins), 220-250 (233); wing, 97-105 (101.9); 

 tail, 85-95 (91.3); exposed culmen, 29-31.5 (30.1); tarsus, 29.5-31 

 (30.5); middle toe, 21-22 (21.9)." 



Adult female.— Length (skins), 220-222 (221); wing, 96-97 (9(5.5); 

 tail, 82-84 (83); exposed culmen, 34-38 (36); tarsus, 30-30.5 (30.2); 

 middle toe, 22. ^ 



Islands of St. Christoplier, St. Eustatius, Saba, Montserrat, Nevis,'^ 

 and Barbuda,*^ Lesser Antilles. 



« These names are all admitted by Lesson to apply to the same bird as that previ- 

 ously designated Ramphjcinclus tremulus by Lafresnaye, but he apparently claims 

 priority because he had already described the species in manuscript. His eccentric 

 action in giving the same bird three different names, in one article,. is more difficult 

 of explanation. 



i* Seven specimens. 



cTwo specimens. 



rfl have not seen a specimen from eitlier Nevis or Barlnida, but these two islands 

 being situated in the same group as the others named it is not likely the Cindocerthia 

 inhabiting them is different. 



Specimens from different islands compare in measurements as follows:
