SALPINCTES. 109 
Troglodytes leucogastra described by Mr. Gould on the same page, 
it is certainly the same, as the C. brunneicapillus is the characteristic 
species of that region of Mexico. 
Campylorhynchus migriceps, Sciater, P. Z. S. 1860, 461.—Is. 
Catal. 18, no. 112 (near Vera Cruz, Mex.). 
This species has a black head and post-ocular stripe like cap7s- 
tratus and rufinucha, but differs in the black nape like jocosus. The 
back is reddish, barred transversely with black. The body is un- 
spotted white beneath, reddish posteriorly ; the tail feathers black, 
barred on the outer webs, and more obsoletely on the inner web of 
the lateral, with fulvous, but without the white tips seen in the allies. 
Campylorhynchus gularis, Scrater, P. Z. S. 1860, 462 (Mexico). 
This is a very short-billed species, closely allied to C. humilis in 
this respect, as well as in the reddish-brown head. The post-ocular 
stripe, however, is said to be black, as well as a rictal one. The 
tail is broadly tipped with white. The two lateral tail feathers have 
large white spots on both webs (not on the outermost only). The 
under part, except the throat, with round black spots; in this also 
differing from humilis.

obsoletus, SAY.) 
This genus is sufficiently characterized in the “ Birds N. Am.,” as 
well as in the general synopsis of the family in the preceding pages, 
for my present purposes. It is, however, especially peculiar among 
all its cognate genera by having the usual two continuous plates along 
the posterior half of the inner and outer faces of the tarsus divided 
transversely into seven or more smaller plates, with a naked interval 
between them and the anterior scutelle. At the upper end of the 
outer plate these divisions or lines of junction are obsolete, becoming 
more distinct below, and near the inferior extremity the plates are 
reduced to oval scales. The plate along the inner face is also divided 
into two or three plates, sometimes more, usually less distinct than on 
the outer. The posterior edge of the tarsus, instead of being sharp, 
is usually, though not always, blunted, by the bending round of the 
outer plate. The lateral toes are quite disproportionate in size, the 
inner with its claw scarcely reaching beyond the end of the second
