506 THE VOYAGE OF H.M.S. CHALLENGER. 



Habitat. — China Sea (A. Adams); Singapore and Ceylon (British Museum); Torres 

 Strait (Brazier). 



I do not know Mr Marrat's Eulima Candida (except from his figure), but greatly doubt its 

 distinctness from this species. The whole aspect of the shells is very much alike ; the size and the 

 slightly rounder and shorter form of the whorls are features so variable in this genus that little 

 can be founded on them ; the form of the apex, which is, perhaps, the safest of all marks, he does 

 not compare, and the fact he refers to of the varices not extending to the apex is a feature more or 

 less common to all varixed shells, and in Eulima particularly untrustworthy. In Eidima, martinii 

 the varix becomes evanescent and discontinuous on the upper whorls, and may easily be overlooked 

 even when present.

February 10, 1873. Tenerife, Canaries. 78 fathoms. 



Habitat. — From the Lofoten Islands to the Canaries and the Mediterranean, from to 

 140 fathoms. 



Fossil. — From the post-glacial beds of Norway (Sars). 



A good deal of confusion has gathered round the nomenclature of this species. The confusion 

 began with Defrance, who (Melaniens fossiles, Die. des Sciences Nat., 1823, vol. xxix. p. 468), 

 describing the Upper Eocene species from Grignon, and distinguishing it from Eulima nitida, Lam., 1 

 another Grignon fossil, says that he has received specimens of Eulima distorta from the neighbour- 

 hood of Angers, "qui ont 7 a 8 lignes de longueur," and he adds, "on trouve dans la baie de Wey- 



1 Lamarck's mistake of confounding Eulima distorta, Defr., with Eulima nitida, Lam., lies outside of our 

 subject.
