this region and several additional ones were obtained. Among those 

 of special interest were Goniocidarispa2nllata, 156 to 158 fathoms; Bris- 

 so^m lyrifera, 158 to 194 fathoms ; Spatangus imrimreus^ 89 to 158 fath- 

 oms; Schizaster canaliferus, 100 fathoms, several; Uchinus Wallisi A. 

 Ag., G40 fathoms ; U. gracilis, nninerous and of large size at stations 

 1097 and 1098, in 156 to 158 fathoms ; Pkormosoma Sigsbei A. Ag., sta- 

 tion 1123, in about 700 fathoms,* seveail, both large and small, the 

 largest 124"^™ in diameter; Porania grandis V., abundant in 156 to 158 

 fathoms ; Odontaster Mspidus Y., abundant in 89 fathoms. 



Among those added to the fauna this year are a very rare IHadema- 

 like sea-urchin {Hemipedina C%ibensis A. Ag.) from 194 fathoms, pre- 

 viously known onlj' from the West Indies; Solaster Earllii V., of which 

 a large nine-armed specimen, bright scarlet, in color, was obtained in 

 234 fathoms, station 1121 ; Lopliaster furcifer, several from 234 and 640 

 fathoms ; Astrogonium gramilare, from 156 and 640 fathoms ; Astrophy- 

 ton Lamarcl-ii, color, bright orange, several from 194 fathoms; Asteronyx 

 Loveni M. & Tr., station 1123, in about 700 fathoms, on a peuuatulid ; 

 color of both bright orange ; Ophioscolex, new sp., with four arm-spines 

 and a small tentacle-scale, 234 fathoms ; RMzocrimis Lofotensis, young, 

 from 640 fathoms. 



Most of the Anthozoat of the previous years were again obtained, with 

 some additional ones, including a remarkable new Pennatulid belong- 

 ing to a new genus, t and two Gorgonians : Acanthogorgia armata V., 

 640 fathoms, and Paramuricea horeaUs Y., from 234 fathoms ; the former, 

 when living, was bright orange ; the latter was pale salmon. Of those 

 previouslj^ taken, one of the most interesting was Pennatula borealis, 

 obtained in 192, 317, and 640 fathoms. The largest one, from 317 fath- 

 oms, was 21.5 inches high, and 5.25 broad. 



Of Pycnogonida, we took some large and interesting forms, including 

 two examples of Colossendeis colossea Wilson, station 1123, in about 700 

 fathoms, of which the larger was 19.5 inches across ; C. macerrima W., 



* The trawl was put down at this station ia 780 fathoms, hut heforc it was taken up 

 the depth had become 627 fathoms. 



t Most of the Authozoa obtained by us have been described and figured by the au- 

 thor in the Bulletin Mus. Comp. Zoology, Vol. XI, 1883. See, also, Amer. Joum. 

 Science, 1881-'82. 



X DisticlwpiUum Verrill. — Slender pennatulids, with an axis through the whole 

 length, and polyps arranged alternately, in a simple row, on each side ; calicles bilo- 

 bed, appressed ; zooids three to each poly}}, one in frout and one on each side of each 

 cell ; spicula abundant in the calicles, rachis, and stalk. 



Disticlioptilum gracUe Verrill. — Long and slender, with a long stalk. Polyp-cali- 

 cles rather large, rigid, closely ai^pressed, with two sharp terminal lobes, filled with 

 spicula, concealing the oj)euing, and overlapping the base of the calicle in frout; 

 aol>id8 small, not exsert, showing as small white spots at each side and in front of each 

 polyp cell; stalk long, slender, with a long narrow bulb ; color, bright orange-red, 

 due to the spicula ; end of bulb yellowish ; length, 18 inches, or 456™'" ; breadth in 

 middle, 2™™ ; length of stalk, 100™™.
