Numerous specimens of this species were found on 

 roots of basket kelp after storms. 



This species is pecuHar to the Falkland Islands. The 

 genus is cosmopolitan in shallow to very deep water. 



MoLLUSCA. 



Out of 45 species of Ivlollusca from Lively Island, 

 Falklands, which Mr. Standen* has identified, 4 occur in 

 the tropics as well as in the southern hemisphere ; one ranges 

 through the southern hemisphere, the tropics and the 

 northern hemisphere, Crepidula dilatata, which extends 

 all along the west coast of America from Patagonia to 

 Alaska, and also occurs in Kamtschatka ; 40 are found only 

 in the southern hemisphere, 29 of which occur only in 

 South America and the Strait of Magellan, whilst 5 are 

 peculiar to the Falklands. 



ECHINOIDEA. 



Go7iiocidaris canaliculata Agassiz, Revision of Echini, 

 p. 395. A single, young, somewhat damaged 

 specimen. 



This species has an extensive distribution. Southern 

 oceans, 1,600-1,975 fath. Sandwich and Navigator Islands. 

 Natal. Falklands, 5-12 fath. 



It ranges along the southern extremities of all the 

 southern continents and extends north of the equator to 

 Japan. 



G. canaliculata has a wider distribution than any 

 other species of this genus, which is restricted, with this 

 exception, to the southern hemisphere and to the tropics. 



An interesting fact concerning this species is that it 

 extends through the tropics to the northern hemisphere
