This is a rather pale form found in Peru. It is very sandy grey 

 above, with the black markings long and narrow, and is a distinct 

 subspecies. I have nevertheless seen examples of the northern form 

 C. texensis which are almost similar in plumage to C. j^ndnosus. 

 Therefore I think that larger material obtained in different localities 

 and at different times of the year will show that this is merely a 

 subspecies.

This is merely a large Northern form of C. acutipennis, and no 

 constant difference can be found, except the large size. This, how- 

 ever, varies in true South-American C. aciitipennis, and specimens 

 approaching C. texensis are not rare.
