Hob. Scotia Bay, South Orkneys, 9-10 fathoms, April 1903. Station 325, 

 contiguous to first locality, 9-10 fathoms, July 1903 ; also shore pools in Scotia 

 Bay, December 6, 1903. 



Quite typical, often encrusted with nullipore. Found likewise in South Georgia.* 

 A further extension of range is now established. 



Family Litiopidse.

,, maculata, d'Orb., Moll. Cuba, ii., p. 149. 



Hob. -With tow-net, surface-dredging, and upon gulf-weed (sargassum) ; in several 

 places, including particularly lat. 9 6' S., long. 31 45' W., December 16, 1902; and 

 lat. 29 54' N., long. 34 10' W., June 29, 1904. 



Very variable, and with a lengthened synonymy, of which only two or three have 

 been given above. 



Family Cerithidse. 



C'erithium georgianum, Pfeft'er.

 Taf. ii., fig. 7 (1886). 



Hob. Scotia Bay, South Orkneys, 9-10 fathoms, April 1903. 



One example only, but in fine condition, entirely agreeing with Dr PFEFFER'S 

 plate and description of his South -Georgian species. It is a curious, small, strongly 

 spirally ribbed and keeled shell, the carinse three in number on the lower whorls, four 

 on the body-whorl itself. The apex is remarkably obtuse.
