Show 1886.] ON ISOPODA COLLECTED BY H.M.S. 'CHALLENGER.' 97 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 ol vmaceous brown; centre of breast and abdomen white. Total length 675 inches, culmen 075, wing 39, tail 2-35, tarsus 0'8. Ine 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 G.japonicus, for it has a greater extent of pure white on the wing-coverts than in even true C coccothraustes. G.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 m y friend Mr Hume, G. humii. Whether it is the Hawfinch recorded by Lieut Barnes as a permanent resident at Chaman in Southern Afghanistan (Str. t. 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. rr J 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 K [Eeceived 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 Munnidce', Asellidce, Arcturtdce, Cymothoido?, 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 explorations carrried out by the ' Challenger.' 1 Published by permission of the Lords Commissioners of the Treasury.
