[TAYLOR] MARINE MOLLUSCA 35 



Whiteaves records it from " Dolomite J^nrrows, abundant ; raoutli of 

 Cumshewa Harbour, in twenty fathoms, several ; Houston-Stewart 

 Channel, in fifteen to twenty fathoms, three or four specimens." 



ASTAETR, J. Sowerby. 



44. ASTARTE UNDATA, (iould. 

 Invei'tebrata of Massachusetts, p. SO (1S41) ; ed. ii., p. 121. 



This species was recorded by Mr. AN^hiteaves from Metlakathi in 

 1878 as Astarte snm'snlcafa, Leach ? 



Jn 1886, after an examination of the specimens collected by Dr. 

 Dawson to the north of Vancouver Island, he withdrew this name and 

 substituted, and we think riglitly, A. undata, Grould, which name we have 

 adopted for our largest Astarte. This is not by any means so abundant 

 a shell hei'e as is the next species, but it is fairly common at Victoria 

 and in other localities in which dredging has been done on the eastern 

 and northern coasts of \'uncouver Island. 



45. A START K PjSquimalti, Baird, sp. 



Cransatella Esquhtialti, Baird, Proc. Zool. Soc, London, 1863, p. 70, pi. ii., tig. 1.5. 

 = Rictocyvia inirabifis, Dall, Anier. .Tour. Conch., vol. vii., p. 1.51, pi. xiv., 

 fig. 6 (Nov., 1871). 



This is our commonest Astarte, and may be easily distinguished by 

 its smaller size and wavy sculpture from the last named species. It is 

 rather rare at Victoria but is abundant at Nanairao and Comox, and 

 was found by Dr. Dawson at several points at the north of Vancouver 

 Island, and also at the mouth of Cumshewa Harbour, Queen Charlotte 

 Islands. 



46. Astarte compacta, Carpenter. 



Rept. Brit. Assoc. 18(W, p. (U2 (August, ISM); and Proc. Acad. Nat. Sci. Pliila., 

 186.5, p. .57. 



A single living specimen was collected by Dr. Kennerle}^ in Puget 

 Sound. Dr. Carpenter described it as " Astarte ( ? var.) compacta," and 

 suggested that it might prove to be identical with A . compressa, Montagu, 

 a European species. 



I do not think that any further specimens of this species ? have 

 been found.

47. IvELLiA Laperousii, Deshayes, sp. 



Chiroiiia Laperuusii, Desh., Rev. Zool. Soc. Cuv., p. 357 (Dec, 18:i9>; and Mag. 

 de Zool. (Guerin's), pi. xii. (1841); var. Chironii, Cpr., Rept. Brit, Assoc, 

 1863, p. 643 (Aug., 1864); and .Tour, de Conch., vol. xii., p. \m (April, 1865). 



This is a very common species usually occurring in the interior of 

 dead bivalve shells. It has been found in all localities in British
