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 unitetl 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 rumj) 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 up})er eyelitl. 



Coloration. — -Pileum grayish brown; throat and cliest 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 ruf escent ground ; tail black. 



Range. — Nicaragua to Panamd. (Monotypic") 



PH^NOSTICTUS MCLEANNANI MCLEANNANI (Lawrence). 



MC'LEANNAN'S ANTTHRTJSH. 



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 conspicuousl}" 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; 



a The genus Phlegopsis Reichenbach (type Myothera nigromandata Lafresnaye and 

 D'Orbigny), to which the type of Phaevosticius 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.
