Mr. P. L. Sclater on a new 
18. tElurcedus stonei, Sharpe. 
A specimen of this species has a greenish head with 
yellowish stripes in the middle, and a yellowish forehead, 
no doubt the remains of the immature plumage. 
19. tElurcedus melanocephalus, Ramsay. 
This species has been lately founded by Ramsay (Proc. 
Linn. Soc. N. S. W. vii. p. 25). The following diagnosis will 
supplement his description :— 
JE. arfakiano, Meyer, similis, sed fascia nuchali nigra et 
maculis tectricum alarum nullis, jugulo et gutture varie- 
gatis, pectore et abdomine brunnescentibus diversus : 
long. tot. circ. 290, al. 152, caud. 120, rostr. 33, tars. 44 
millim. 
This species comes between JE. arfakianus and JE. mela- 
notis of Aroo, but is nearest to the former. In its throat 
being not black it approaches jE. melanotis , although this 
part is somewhat dark in JE. melanocephalus. In its dark 
head it resembles JE. arfakianus , but there is no sharply 
defined cervical band. The uniform green wing-coverts re¬ 
mind one of JE. buccoides of Western New Guinea and 
JE. stonei of Southern New Guinea. JE. melanocephalus 
seems to be darker than JE. arfakianus on the under surface 
of the tail, and to have a narrower terminal band. The 
feathers of the throat in JE. melanocephalus are black at the 
bases and tips, but have a broad white intermediate band, so 
that the white predominates, whereas in JE. arfakianus the 
black predominates. The whole under surface is washed with 
olive-brown, and is much darker than in JE. arfakianus and 
JE. melanotis. 
XXX.— Description of a new Ground-finch from Western 
Peru. By P. L. Sclater, M.A., Ph.D., F.R.S. 
(Plate VIII.) 
My excellent and much valued correspondent, Prof. William 
Nation, of Lima, has lately sent me a single skin of a 
Ground-finch from the upper valley of the Rimac, which 
seems to belong to an undescribed and very distinct species
