*35. Myiobius capitalis Salvin.* 
Apparently rare; one specimen, shot in a dense forest. 
“37. Contopus depressirostris Ridgway, sp. nov.t 
Not common. Two specimens shot in scrub timber and edge of 
forest. 
Fam. PIPRIDA. 
*38. Chiromacheris candzi (Parz.). 
Rare. Only one specimen secured in dense forest on the other side 
‘of the tributary river which enters the San Juan del Norte at Los 
Sabalos. 
*This species seems to me to be quite as properly referable to Mitrephanes (cf. 
CouEs, Bull. Nutt. Orn. Club, January, 1882, p. 55) as to Myiobius. In fact, 1 would 
prefer placing it in that genus. It is true that it differs from the type species 
(M. pheocercus) in certain details of structure, but at the same time it differs more 
from the typical Myiobii. Of the two hitherto known species of the genus, M. phao- 
cercus and M. aurantiiventris, it approaches most nearly to the latter, both in form and 
coloration. It differs from both, however, in the less developed crest and in the more 
rounded wing, the primaries exceeding the secondaries by only about .40 of an inch, 
instead of .60-.70, as in the above-named species. The bill is also longer in propor- 
tion to its breadth, but is otherwise of similar form; and the tail, instead of being 
decidedly emarginate, is distinctly, though slightly, rounded. 
Its coloration at once suggests that of M. aurantiiventris, the back, breast, and cris- 
sum being almost exactly the same color; but M. aurantiiventris has the throat fulvous, 
instead of white; the pileum dark olive, instead of slate, and the posterior lower 
parts much dull:r yellow, and also much less abruptly of this color; besides, the 
_ white supraloral line and orbital ring of M. capitalis are totally absent. 
Mr. Nutting’s specimen, which appears to be the second on record, may be described 
as follows: 
Sp. cH.—Adult g¢ (No. 91,233, Los Sabalos, Nicaragua, May 4, 1883; C. C. Nut- 
ting). Entire pileum uniform brownish slate, this color extending over the auricu- 
lars, which, however, have whitish shaft-streaks; lores slate-gray, bordered above 
by a distinct white line extending back to and involving the eyelids; back, scapulars, 
and rump bright greenish-olive, in abrupt and very marked contrast with the slate- 
color of the head; lesser wing-coverts olive, but rest of wings dusky, the middle and 
greater coverts tipped with bright ochraceous (forming two distinct bands), and ter- 
tials broadly edged with the same; other remiges narrowly and rather indistinctly 
edged with light brownish. Tail light grayish-brown, the feathers edged with a 
more fulvous tint. Chin and throat dull white; jugulum and breast bright ochra- 
ceous, tinged with olive laterally ; abdomen and sides bright primrose yellow; cris- 
sum buff; axillars and lining of wing yellowish ochraceous. Inner webs of remiges 
broadly edged with buffy ochraceous. Bill black, the base of the mandible pale 
colored; feet dark brownish. 
Wing, 2.40; tail, 2.30; culmen, .50; width of bill at base, .30; tarsus, .60; middle 
toe, .32. 
tCONTOPUS DEPRESSIROSTRIS Ridgw. MS. 
Sp. co.—Adult: Above grayish hair-brown, the pileum decidedly darker; middle 
and greater wing-coverts tipped with pale brownish-gray, forming two rather dis- 
tinct bands across the wing; tertialsedged withthe same. Tail slightly but decidedly 
emarginate, uniform grayish hair-brown. Chin and throat grayish-white; sides of 
head, jugulum, breast, and sides, brownish-gray; middle of belly, anal region, and
