BIRDS OF NORTH AND MIDDLE AMERICA. 135 
toe, the inner toe slightly but decidedly shorter; hallux as long as 
inner toe, much stouter; basal phalanx and half of second phalanx 
of middle toe united to outer toe, the former united for a little more 
than half its length to inner toe; claws moderate in size and curva- 
ture, that of the hallux much shorter than the digit. Plumage full, 
the scapulars, interscapulars, and feathers of under parts broad, 
distinctly outlined, and compactly webbed, those of rump and 
flanks more elongated and lax; feathers of pileum short; loral, sub- 
orbital, and postocular regions naked, the ear quite exposed; a 
tuft or spot of short velvety feathers on upper eyelid. 
Coloration.—Pileum grayish brown; throat and chest black; back, 
scapulars, and wing-coverts olive-brown or tawny-brown with large 
roundish black spots, the under parts with similar but smaller spots 
on a more rufescent ground; tail black. 
Range.—Nicaragua to Panam&. (Monotypic.*) 
PHAENOSTICTUS MCLEANNANI MCLEANNANI (Lawrence). 
MC’LEANNAN’S ANTTHRUSH. 
Adults (sexes alike).—Pileum plain grayish brown (sepia to dark 
broccoli brown); hindneck chestnut or rufous-chestnut; general color 
of upper parts light olive-brown (between raw-umber and broccoli 
brown), each feather of back, scapulars, wing-coverts, and tertials 
very conspicuously marked with a large roundish or transverse 
broadly elliptical subterminal spot of black, and broadly margined 
terminally with pale brownish buff or clay color; tail black or 
brownish black; loral, orbital, and auricular regions unfeathered, 
except for scattered bristly feathers on the first and a small patch of 
black feathers immediately above and another beneath eye, the 
naked skin azure blue in life; malar region, chin, throat, and upper 
chest uniform black; lower chest deep cinnamon-rufous, the lower 
chest similar but slightly paler or duller, each feather with a large 
roundish, subcordate, or broadly elliptical transverse spot of black; 
@ The genus Phlegopsis Reichenbach (type Myothera nigromaculata Lafresnaye and 
D’Orbigny), to which the type of Phenostictus has hitherto been referred, differs 
conspicuously in shorter and slightly rounded tail (only two-thirds as long as wing, 
graduated for less than one-seventh its length) of, apparently, only 10 rectrices; very 
dense, plush-like, feathering of forehead and anterior half of loral region; wholly 
(and densely) feathered malar region; covered ears; weaker bill, with less sharply 
ridged culmen and less elevated as well as broadly rounded mesorhinium, and wide, 
smooth, naked space between nostril and loral feathering. The coloration, too, while 
somewhat similar is really very different, the head, neck, and under parts being 
uniform black, the remiges and tail chestnut, the feet black instead of yellow, and 
the naked skin on sides of head yellow instead of blue (in life). 
I have not seen Formicarius trivittatus Sclater nor F. erythropterus Gould, both of 
which are referred by recent authors to Phlegopsis, but, according to descriptions, 
these are so different in their style of coloration that the matter of their structural 
characters should be carefully looked into.
