water at Port Neville, near Johnston Strait. This would bean unusual 

 station for the species, as it is generally found in deeper water and com- 

 pletely encased in a '• nest " constructed chiefly of its own byssal threads.

Distribution aiid station similar to those of M. loivigata, but the 

 present 8]>ocies does not construct a " nest." 



24. MoDiOT.ARiA Taylori, Dall, MS. 



This species has been found by me abundantly at Victoria, between 

 tides, nestling at the roots of corallines. It is a small species not ex- 

 ceeding half an inch in total length and resembling in habit M. discors, 

 Linne, of British seas. 



This species has not been described, but has been widely distributed 

 under Dr. Dall's manuscript name.

Recorded by Carpenter in his " Supplementary Report " as from 

 I'uget Sound (Keunerley, one specimen), Avith the remark, '■ Exactly 

 accords with Atlantic specimens." 



I was inclined to think at one time that the last named species 

 might be the one intended, but it is so very different to M. marmorata, 

 that Dr. Carpenter could not have made such a mistake. Moreover, I 

 lind that M. marmorata is on record from several other localities in the 

 Pacilic Ocean both to the north and the south of us. It is also found, 

 according to Jeffreys/ in Japan.

 depths. Our shells are much larger than Atlantic specimens. Mr. 



' " On some Species of Japanese Marine Shells and Fishes whicli inhabit also the 

 North Atlantic," by J. Gwyn JettVeys in Journal oftheLinnean Society (Zoology), 

 vol. xii., p. 100, November, 1874. In this paper Dr. Jeffreys mentions more than forty 

 species of mollusca common to Japanese and European v^'aters, and, as might be 

 expected, the majority of these species occur also on the West American coast. 

 Several additions to the list have been made by sub.sequent vk'riters.
