ee, | Nexson, Mew Birds from Mexico and Guatemala. 71 
The type of this form came from the high, cold table-lands 
about Chancol at an elevation of ten thousand feet. ‘There they 
were common in the open pine forest. In the lower and warmer 
district about Nenton, Guatemala, with typical examples of 
neglectus, we obtained two specimens that, while agreeing with the 
Chancol bird more than with odsoletus, show a gradation toward 
the latter, and this probably continues through Chiapas. Speci- 
mens from the plain about Quezaltenango and the adjacent 
Volcano of Santa Maria are like the Chancol specimens. 
Although I have no specimens of S. gud¢fatus at hand, the ce- 
scription of that species shows it to be distinct from /eglectus. 
Hylorchilus,! new genus. 
Type, Catherpes sumichrastr Lawre. Proc. Acad. Nat. Sci. Phila., 1571, 
P- 233- 
The specimen used in describing the characters of this genus is No. 
142878, U. S. Nat. Museum, Dept. Agric. coll., J (?), Motzorongo, Vera 
Cruz, Mexico, March 5, 1894. Collected by E. W. Nelson and E. A. Gold- 
man (Orig. No. 1806). 
Generic Characters.— Like Microcerculus, this genus is characterized 
by the plainness of its dark brown plumage, the tail and wings being 
unmarked, as is most of the body. . The secondaries are almost of the 
same length as the primaries, and the tail is short and spiky in form, 
being made up of soft slender feathers narrowed gradually at the tip. The 
tail is so short that it does not reach to the end of the outstretched feet in 
the dried skin. The body is short .and stout, with strong legs and feet 
as in Microcerculus. The bill, however, is more as in Catherpes, being 
long, unnotched at the tip and with similarly narrow, oval, slit-like nares. 
The bill is heavier and its curve is decidedly less than in Catherfes 
mexicanus, the nares are slightly inclined toward the front instead of being 
parallel to the gape as in Catherpes, and the membrane forming the 
upper border of the orifice is a little curved and inflated along its edge. 
Catherpes sumichrasti was described from a single imperfect 
specimen taken at Mata Bejuco in Vera Cruz, Mexico. Owing to 
the absence of the tail in the only known specimen, it has been 
referred provisionally to the genus Cavherfes by all subsequent 
authors. Fortunately we secured two perfect specimens at 
1 dA, forest, and épxidos, wren, in reference to the habits of the type 
species.
