CAMPYLORITYNCHUS. 9$ 
feathers of crissum are tinged with rusty, and with a central brownish streak. 
Bill horn-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 Ist primary, 1.32, of 2d, 2.20, of longest, 4th (measured from exposed base 
of Ist 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, .$5; 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 Americar 
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-
