108 REVIEW OF AMERICAN BIRDS. [PART I, 
separate it from capistratus. It is less spotted beneath than rufi- 
nucha. The bill is considerably shorter than in any of these species ; 
the tarsi as short as in rufinucha. 
The specimens before me agree sufficiently well with the descrip- 
tion by Dr. Sclater of C. humilis, based on a bird in the museum 
of the Phila. Academy. Although No. 29,225 is larger than the type, 
a skin received from Mr. Verreaux, 22,382, agrees more nearly with 
it in this respect. A skin collected by Mr. Xantus, near Colima, and 
belonging to the same region as the Mazatlan specimen, is undis- 
tinguishable from the Orizaba skin, upon which the description above 
given is based. In this the iris is said to be red-brown. In the 
brown head and other characters, as well as the short bill and tarsi, 
it is related to C. gularis, of Sclater, although this appears to pre- 
sent other distinctive characters. 
Nore.—Since writing the preceding description, I have had the 
opportunity of examining Mr. Sclater’s type in the Phila. Academy, 
from Mazatlan. The species appears to me the same, the type differ- 
ing only in being of rather duller plumage above, the markings not 
so well defined, and in having the bars of the crissum less distinct, 
and externally reduced somewhat to a central spot. There are no 
distinct spots on the flanks.

The following species of Campylorhynchus I have not had the 
opportunity of examining :— 
Campylorhynchus guttatus, Larr. R. Z. 1846, 94.—Thryothorus 
guttatus, Gouup, Pr. Z. 8S. 1836, 89 (Mexico). 
This species, which has not been referred to by recent writers, 
belongs to the same section as C. brunneicapillus, ete., with reddish- 
brown head, and back striped longitudinally with white. The 
throat and breast are said to be spotted with black, the abdomen 
and sides with smaller spots of the same. Length, 6.75 (probably 
more); wings and tail three inches each. The description of the 
tail is not very distinct ; but in several respects there is a close re- 
lationship to C. brunneicapillus, of Lafr., and it is not impossible 
that it refers to the same species. If from Tamaulipas, like the
