CAMPYLORIIYNCHUS. 



99 



feathers of crissum are tinged with rusty, and with a central brownish streak. 

 Bill horu-color, lighter along the commissure and beneath. Legs light-brown. 

 Total length, 7.60 ; wing, 3.50 ; tail, 3.60 ; graduation, .82 ; exposed portion 

 of 1st primary, 1.32, of 2d, 2.20, of longest, 4th (measured from exposed base 

 of 1st primary), 2.60; length of bill from forehead, 1.00, from nostril, 1.65 ; 

 along gape, 1.10; tarsus, 1.00; middle toe and claw, .85; claw alone, .23; 

 hind toe and claw, .74 ; claw alone, .35. 



This species is quite closely allied to C. unicolor, of Lafresnaye, 

 which is pretty uniformly brown above, dirty white beneath, with a 

 few brownish spots on the crissum. 



There is very little in the species to distinguish it generically from 

 the type of Campylorhynchus.

I find it quite impossible to reconcile Lafresnaye's description of 

 C. brunneicapillus, much less his figure with the North American 

 bird. This is described as having five white spots on the outer web 

 of the lateral tail feather, and three on the inner; the next with 

 two on the outer and three on the inner web (perhaps three outer 

 and two inner) ; the third and fourth with marginal points instead 

 of spots. 



This particular pattern of coloration I have not observed in any 

 specimens of our bird, and the spots are larger than as described, 

 although the markings of the tail vary a good deal. Lafresnaye, 

 however, describes the under parts as pale rufous from the upper 

 part of the breast to the tail (represented also in the plate), instead 

 of having this rufous confined to the abdominal region. The speci-
