back, rump, and upper tail-coverts, while the crown of the head is 
ashy grey like the hind neck ; sides of face also ashy grey washed 
with ochreous; breast and sides of the body ochreous buff, instead 
of vinaceous brown; centre of breast and abdomen white. Total 
length 6°75 inches, culmen 0°75, wing 3°9, tail 2°35, tarsus 0°8. 
The male differs less from C. coccothraustes than the female, but 
it is distinguished by its paler coloration, and by the breast and sides 
of the body being light orange-brown instead of vinaceous. Total 
length 6°9 inches, culmen 0°8, wing 3°8, tail 2-1, tarsus 0°8. 
I may add that the Attock bird is not CO. japonicus, for it has a 
greater extent of pure white on the wing-coverts than in even true 
C. coccothraustes. C. japonicus is scarcely to be distinguished from 
the European bird; and differs only in having the median and 
greater wing-coverts pale drab at the ends instead of white. I 
propose to call the Coccothraustes from Attock after my friend Mr. 
Hume, C. humii. Whether it is the Hawfinch recorded by Lieut. 
Barnes as a permanent resident at Chaman in Southern Afghanistan 
(Str. F. ix. p. 456) must remain a question to be decided by an 
examination of specimens, which I have not yet had the opportunity 
of doing. 
4, Preliminary Notice of the Isopoda collected during the 
Voyage of H.M.S. ‘Challenger.’—Part III. By 
Frank E. Bepparp, M.A., F.R.S.E., F.Z.S., Prosector

[Received January 25, 1886.] 
The present paper completes the preliminary description of the 
new species of Isopoda collected during the voyage of the ‘ Challenger.’ 
This paper includes the families Munnide, Asellide, Arcturide, 
Cymothoide, Spheromide, Tanaide, Anceide, and Anthuride, of 
all of which there are specimens in the ‘ Challenger’ collection, 
representing about 45 new species, besides a number of others 
previously known. Among the shallow-water species the largest 
number of new forms are from Kerguelen, in spite of the investigations 
into the marine fauna of that region carried out by the British 
‘Transit of Venus Expedition,’ and the exploring voyage of the 
German S.S. ‘Gazelle.’ I have to add quite as many new species 
as those previously known to the fauna of Kerguelen and the adjacent 
islands (Prince Edward’s Island, &c.). 
Among the deep-sea species the most remarkable and interesting 
is undoubtedly a new genus of Cymothoade, which is described below 
under the name of dAnuropus branchiatus; there are also numerous 
representatives of other deep-sea forms, as might be expected from 
the nature of the explorations carrried out by the ‘ Challenger
