360 THE MOLLUSCA COLLECTED BY THE " HUXLEY " FROM THE 



to the fauna of the actual Bay of Biscay, it had been previously found 

 and recorded from off the coast of Portugal by the TmvalUcur. 



Lima excavata (Fabricius). — Fragments and odd valves of this 

 northern species have been found south of the Bay of Biscay, by the 

 Porcupine off Cape St. Vincent, and by the Talisman off the west coast 

 of the Soudan. The single specimen found during the HiLdey cruise, 

 though smaller than the northern specimens I have seen, contained the 

 animal, and thus proves its extended habitat, which was suggested by 

 the discovery of the above-mentioned fragments. 



The two species of Scaphopoda are both recorded as British. 



Of the non-British Gastropods, two cannot be identified on account 

 of their condition, but the remaining eight species are of interest. 



Emarginula riiultistriata , Jefi'reys. — A Mediterranean species 

 recorded from off the coast of Portugal. 



Calliostoma obesnlum (P. Fischer) and C. deopatra (P. Fischer) have 

 only been recorded from off the Atlantic coasts of Northern Africa, 

 and the fact of their having been found living, the former in large 

 numbers, so far north, is a valuable indication of the possible very 

 wide distribution of deep-water species. 



Natica operculata, Jeffreys. — Jeffreys records the species as having 

 been found by the Forcupinc off the Spanish coast. 



Randla gigantca (Lamarck). — The most northerly habitat of this 

 species so far recorded. 



Scala richardi (Uautzenberg and de Boury). — This species has not 

 been found living, the type being described from a dead shell dredged 

 off the Azores. The remarks applied to the two species of Calliostoma 

 apply to this species as well. 



Pseudomurex richardi (P. Fischer). — Previously recorded from the 

 Bay of Biscay. 



Cavolina trispinosa (Lesueur). — Has an almost world-wide dis- 

 tribution, but is probably killed by coming into cold areas. 



I tender my sincere thanks to the following gentlemen for their 

 kind assistance in many ways : Mons. Ph. Dautzenberg, Sir Charles 

 Eliot, K.C.M.G., Mr. E. E. Sykes, b.a., Mr. E. A. Smith, ls.O:, and 

 Mr. H. B. Preston, F.z.s. Finally I feel very much indebted to Dr. 

 E. J. Allen for allowing me the opportunity of examining a collection 

 of material of very considerable interest in many ways.
