Family SIPHONARIIDAE 



Genus Kergulenella Powell, 1946 



n.nom. for Kerguelenia Rochebrune & Mabille, 1887 non Stebbing, 1888 (Crustacea) 



Type: Siphonaria lateralis Gould, 1846 



Kerguelenella lateralis (Gould) 



Siphonaria lateralis Gould, 1846, p. 153. 



Siphonaria redimiculum Reeve, 1856, pi. 5, fig. 24.

Siphonaria lateralis Rochebrune & Mabille, 1889, p. 29. 



Siphonaria lateralis Strebel, 1907, p. 172, pi. 3, figs. 27-290. 



Siphonaria (Liriola) lateralis Thiele, 1912, p. 250. 



Siphonaria (Kerguelenia) lateralis Hubendick, 1946, p. 26, pi. 1, figs. 22-25. 



Type locality. Burnt I., Orange Harbour, Strait of Magellan. 

 St. MS 70. Maiviken, west Cumberland Bay, South Georgia, 9 Mar. 1926, shore coll. 



The ' Discovery ' South Georgian specimens have low rounded ribs and are exactly as in Hubendick's 

 figures of material from this same location. Topotypes, however, agree with Strebel's figures in having 

 sharply raised radial ribs. 



Hubendick has synonymized with lateralis my macquariensis (Powell, 1939, p. 238) from Macquarie 

 Island. It is certainly nearer to South Georgian examples than to Tierra del Fuegan topotypes, but 

 appears to differ from both in being constantly more elongate. Unfortunately no animals are available 

 for study. 



Range. Patagonia, Strait of Magellan, Falkland Is., South Georgia (Hubendick, 1946) and possibly 

 Kerguelen I. Hubendick's Auckland, Campbell and Antipodes I. records refer to undescribed species 

 and the Tasmanian record is most unlikely. An example from St. WS 123. Gough I., is too immature 

 for exact determination.
