256 Mr. W. S. M. D'Urban on the 



Goodsiri), nine species of Echinodermata (including Antedon 

 Eschrichtii) , ten species of Annelids, four species of Polyzoa, 

 six Hydroids (including Myriothela phryyia, Fab., and a very 

 large species of Lucernaria), and several sponges were ob- 

 tained on July 31 and August 1, 1879. 



When it is considered that Mr. Grant only took such things 

 as were not required by the Dutch naturalists, the above lists 

 will convey some idea of the profusion of animal life in 

 Barents Sea. 



Certain animals seem almost universally distributed in 

 this region, such as the interesting tube-worm Cystenides 

 hyperborea, which came up in almost every dredging and in 

 great numbers. The Ophiurids Opht'octen sericeum, Ophio- 

 pholis bellis, and Ophiacantha spinulosa also occurred almost 

 everywhere, and sometimes choked the dredge with their 

 masses. Ctenodiscus crispatus was also very generally dis- 

 tributed at all depths from 62 to 210 fathoms. 



Off the north coast of Norway, just outside Barents Sea, 

 the Ophiurids were scarce, and, on the contrary, Brachiopoda, 

 which were rarely met with in Barents Sea, abounded, at least 

 in individuals. 



The annexed list of species (p. 258) is tabulated in a 

 similar manner to that given by Dr. Marenzeller ; and the 

 two can therefore be readily compared with each other. 



SPONGIA. 



Mr. Henry J. Carter, F.R.S., has kindly furnished the 

 following descriptions of the two new Sponges : — 



Suberttes montalbidus. 



Form monticular. Colour grey-white. Surface corrugated. 

 Vents, one large on the summit, naked, the rest small, on the 

 sides. Texture soft, matted. Spicules of two kinds, viz. : — 

 1, skeleton, large, subpinlike, head variable in shape ; 2, 

 flesh-spicule, minute, shaft cylindrical, straight or curved, 

 pointed at each end and inflated in the centre. Size of speci- 

 men ll-12ths inch in diameter at the base, 8-12ths inch 

 high. 



Suberites montiniger. 



Form monticular. Colour grey-black. Surface even. 

 Vents, one large at the summit, fringed, the rest small, on the 

 sides. Texture soft, matted. Spicules of one kind only, viz. 

 skeleton, large, subpinlike, head oval, elongated. Size of 

 specimen 13-12ths inch in diameter at the base, 8-12ths inch 

 high.
