indicated by Koehler's photographic figures of spinidatiis. The supposed diflFerence in 

 the shape of the furrow spines does not exist. 



A priori there is nothing surprising in the occurrence of loripes at Kerguelen in 

 shallow water, as temperature is probably the important factor for its survival at any 

 sub-Antarctic locality. Although the race has not been recorded from Macquarie 

 Island it probably occurs there in appropriate surroundings, since a common Falkland 

 species, Anasterias antarctica, has been taken. The latter species is the more surprising 

 because it carries its eggs and young and lacks the advantage of pelagic larvae. Bathy- 

 biaster probably has pelagic larvae. 



B. loripes more closely resembles B. vexillifer than does obesus. Vexillifer varies 

 considerably in respect to the spinulation of the marginal plates, so that comparison of 

 this character is unsatisfactory. Vexillifer appears to have consistently longer, hence 

 fewer, marginal plates, as noted under Bathybiaster, above. 



Goniopecten fleiiriaisi Perrier, from Beagle Canal, south coast of Tierra del Fuego, is 

 clearly B. loripes. Bottom temperatures recorded: 198 m., 8-i° C. ; 270 m., 7-7° C. 



Type locality. Challenger St. 3 1 1 , oflF the western coast of South America, near the 

 entrance to the Strait of Magellan, opposite Port Churruca, 245 fathoms, blue mud, 

 bottom temperature 46° F. 



Distribution. Strait of Magellan and western entrance, 198-490 m. (Sladen, 

 Perrier); plateau of the Falkland Islands, 219-342 m. ('Discovery'); Kerguelen Island, 

 shallow (Koehler).

This form has been fully described and figured by Koehler. It is regrettable that his 

 name, liouvillei, is untenable. It is apparent from Sladen's description that his Kerguelen
