OF NEW OR LITTLE KNOWN BIRDS. 287 



Wings four inches : spurious quill half the length of 

 the second. 



Inhabits Southern Brazil. Mus. Nost. 



The smallest of the black-caped species yet discovered, being 

 much inferior to size to P. erythrogcnys. Total length about 

 6| inches ; bill, gnpe 1-jL; ditto, front |jj; wings 4; tail, base 

 '2\ ; tarsus fg. First quill intermediate in length between the 

 fourth and fifth perfect quills. The slight characters which I 

 originally gave of this species had better be cancelled for the 

 foregoing. 



21. PsARis strigatus. 



Grey : beneath^ dusky ferruginous : head blackish : 

 Avings with a broad longitudinal stripe of rufous. 

 Spurious quill broad, hatchet-shaped. 



Inhabits Brazil. Mus. Paris. 



Total length 7 inches ; bill, from the gape 1^ ; ditto from the 

 nostrils fg; wings 3-,'^ ; tail, base 27g; ditto, beyond the wings 

 1|^ ; tarsus -^ : spurious quill hatchet-shaped. Closely related to 

 Psaris cristatus *, but distinguished, at first sight, from that 

 by the broad longitudinal stripe of ferruginous or rufous, 

 which passes over part of the wing covers and the middle 

 portion of the latter quills : rump and upper tail covers grey, 

 tinged with rufous : all the under parts pale ferruginous, 

 deepest on the under tail covers ; inner wing covers the same-. 

 base of the inner web of the quills with a white spot, and a 

 very small concealed one at the base of the shoulders, as in 

 P. cristatus. Both these birds are links of connection between 

 Psaris and Pachyrynchus. 



22. Pachyrynchus megacephalus. 



Head very large : plumage, above, cinereous ; be- 

 neath, whitish : crown of the head glossy black : wings 

 brown ; quills rufous : ears, and inner web of the tail 

 feathers, fulvous brown. Wings rather short, rounded : 

 no spurious quill. 



Inhabits Brazil. Mus. Nost. 



Total length 7| inches ; bill, from the front ^ ; ditto, gape 

 1; wings 4; tail, beyond, \\; from the base 3; tarsus ^^. 

 Head very large, crested : bill small, strong, and nearly as 

 high on the sides as it is broad above; so that it deviates more 

 from the typical species than any I have yet seen : crown and 

 nape glossy black : upper plumage cinereous ; but the whole of 

 * Zool. 111. ii. pi. 41.
