[TAYLOR] MARINE MOLLUSCA 33 



I do not know of any other record of the occurrence of this eastern 

 American species on the Pacific coast. 



36. YoLDiA LANCEOLATA, J. Sowerhy, SJ), 

 Nucula lancroiafa, J. Sby., Mineral Coiicholo^y, 



Fairly common at A^ictoria, Nanairao, etc., and occurring also at the 

 Queen Charlotte Islands and in Quatsino Sound (Dawson). 



The " very large " specimens recorded from Comox bj^ Dr. Newcombe 

 should probably be referred to the next species. 



37. YOLDIA SEMINUDA, Dall. 

 Anier. Journ. Conch. ,1 vol. vii., p. 15;i(Nov., 1871). 



This species might be mistaken at first sight for Y. lanceolata, l:)ut 

 when carefully examined it is seen to be quite distinct. It is a larger 

 species than lanceolata, and the diagonal sculpture does not extend 

 beyond the middle line of the shell, while in the last named species- 

 it reaches to the anterior margin. 



Y. seminuda was described from St. Paul's Harbour, Radiak, 17 fms. 

 My specimens were dredged outside Victoria Harbour, and the species- 

 has not so far been recognized elsewhere in the province. 



38. YoLDiA LiMATULA, Say, sp. 

 Niinda litnatula. Say, American Conchology, pt. ii., pi. xii. (April, IS^I). 



I dredged this species in Departure Bay in 1888, and near Victoria 

 in 1891. It is like the two last named species in colour, but lacks the 

 diagonal grooves they both possess. 



This shell was identified for me by Dr. Dall. 



39. YoLDiA, species. 



Three fine specimens of a Yoldia that I have not yet identified were- 

 obtained last year in Sooke Harbour by Professor Macoun. The species, 

 resembles Y. limatula in colour, but ditters in its very jieculiar shape. 



-40. YoLDiA AMYGDALEA. Valencienues. 

 Zool. Voy. Venu.s, MoUusca, pi. xxiii., tis- (> (184(5». 

 This species has been dredged at Victoria, Departure Bii}- antt 

 C'Omox, but appeal's to be rather rare. Its dark colour and the absence 

 of the diagonal sculpture distinguish it from the preceding species. 



^ The paper in which Y. seminuda and some seven or eight others ot our Briti.sh 

 Columbian speciesare described is entitled "Descriptions of (iOnew forms of Mollusks 

 from the west coast of North America and the North Paciflc Ocean, with notes on 

 others already described ." It was published in the American Journal of Conchology 

 for 1871, vol. vii., pp. 93 to 160, plates 13 to 16.
