OF NEW OR LITTLE KNOWN BIRDS. 357 



blue on the plumage, nor yellow on the wing covers, and is pe- 

 culiar to Brazil : in this, on the contrary, the middle of the 

 breast and body, down to the vent, is of a bright caerulean 

 blue : the rich rufous of the head extends so as to margin the 

 chin round the base of the lower mandible : the thighs are rufous. 



221. Arremon semitorquatus. 



Upper mandible of the bill black ; the lower yellow : 

 neck with a black semi-collar^ open in front. 



Inhabits Brazil. Mus. Nost. 



Size and colour of A. flavirostris, No. 198. : but the white 

 stripe, which in that species commences behind the eye, takes 

 its origin, in this, from the nostrils, as in torquatus, and conse- 

 quently passes over the lores; the bill is shorter, and thicker at 

 the base; and the wings are also rather shorter : the legs and 

 feet are dark brown, instead of a light fulvous ; nor is the outer 

 edge of the carpus bright yellow : the semi-collar is so inter- 

 rupted' as to leave only two black patches : the tip of the chin 

 is also black. 



222. SUBGEN. PiPREOLA. 



SuBGEN. Character. — Wings moderate ; the pri- 

 maries not narrowed : tarsus shorter than the middle toe ; 

 lateral toes nearly equal_, the inner being scarcely shorter 

 than the outer ; inner, cleft to the base ; outer toe con- 

 nected to the middle only as far as the first joint : tail 

 very short. 



The peculiar structure of the feet in this bird, so different 

 from that of the typical Pipree, induces me to consider it as 

 the type of one of the subgenera ; Metopia is probably an- 

 other ; and I have an imperfect acquaintance with a third. 



Pipreola chlorolepidota. 



Above, parrot green ; beneath, yellow, each feather 

 having a green border : chin with a central stripe of 

 orange yellow : quills tipt with white. 



Inhabits Peru. Mr. W. Hooker's Collection. 



Size of a Robin. Total length Scinches; bill, front ^^ ; from 

 the gape -f^; wings 3 ; tail, beyond -f^; base 2 ; tarsus, ^ ; middle 

 toe and claw -i . ,.The green is particularly vivid on the back ; it 

 forms a inargin round the breast feathers, which are pale yellow- 

 ish, having an additional blackish lunule in the centre, only seen 

 when the feathers are raised : these marks almost disappear on
