back, rump, and upper tail-coverts, while the croiun of ike 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 675 inches, culmen Ov5, 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 G-9 inches, culmen 0-8, wing 3-8, tail 2-1, tarsus O'S. 



I may add that the Attock bird is not C.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, G. 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 1 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. Beddard, M.A., F.R.S.E., F.Z.S., Prosector 

 to the Society ^ 



[Received January 25, 1886.] 



The present paper completes the prehminary description of the 

 new species of Isopoda collected during the voyage of the ' Challenger.' 

 This paper includes the families Munnidce, Asellidce, Arcturidce, 

 Cymothoidce, Sphceromidce, Tanaidce, Anceidce, and Anthuridce, 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 Cymothoadce, which is described below 

 under the name of Anuropus branchiatus ; there are also numerous 

 representatives of other deep-sea forms, as might be expected from 

 the nature of the exi)loratious carrried out by the ' Challenger.'
