A new species in the collection of Lord Derby and m the British 

 Museum, forming a second type-species, I have called 



Ps. pARiNUS, Kaup. 



Size oiParus major ; head-feathers black, with a soft violet lustre, 

 and not imitating the form of scales ; lorum, ear-covers and all the 

 under parts dirty white ; the whole back and shoulder-covers grey ; 

 the little plumage of the wings black or grey, with whitish margins ; 

 hand-wings black, arm-wings dark grey, marginated with whitish 

 yellow ; the inner webs of the wings broadly marginated with whitish 

 yeUow ; tail-feathers grey, along the shafts black and on the margin 

 narrowly bordered with yellowish white ; the second abnormous hand- 

 feather with broader inner web black, with vyhite margin from the 

 emargination to the end, and with a large long white spot from the 

 root to two-thirds of the feather. 



The female rufous with darker head ; wings black-brown, with pre- 

 dominating rufous yellow margins ; belly and under tail-covers hghter- 

 coloured. 



This species comes from Para. 



Very near to this species must be placed the Psaris sunnamus 

 (Muscicapa, Gmel.), which is characterized with the following dia- 

 gnosis : — Cauda rotundatd, apice alba; corpore nigro, subtus albo. 



I have not hitherto seen this species, nor Ps. niger variegatus and 

 melanoleucus. . ^^ An

Genus Setophaga, Swains. 

 This genus is one of the finest of the whole family of Muscicapidee. 

 It is found only in America. Only one species inhabits the northern 

 part, namely the very distuict species. Set. ruticilla, with its yellow 

 or red-banded wings and tail. The tail-feathers are pointed. 



The greater part inhabit the southern parts. They form various 

 little subgenera, distinguished by their very different colouring. One 

 of these, and I think the most beautiful, is the little section to which 

 the following species belong. They have much yellow on the head 

 and under side ; on the over parts dark cinereous. 

 Setophaga rtjficoronata, Kp. 



Biag.— With, red head-spot ; the first tail-feather all white. 

 j5e5cr.— The hind ear-feathers black ; front, lorum and eye-region 

 yellow ; the first tail-feather all white ; the second white, with black 

 spot on the outer web, and black margin on the inner web ; under 

 tail-covers black-spotted. 

 Mus. Derbyanum.
