 Island, in 40 to 70 fathoms mud, with the exception of the 

 Megcrlia which was taken only at the first mentioned locality. 

 Hemitliyris psittacea, Linn. (Sp.) Several. Alive. 

 Terebratulina unguicula, Cpr. Rather abundant. Loop complete. 

 Laqueus Californicus, Dall ex Koch. Four living specimens. 



Identified by W. H. Dall.

Cardium Richardsoni, (N. Sp.) * 1 For description of this species 



see the foot note below. 



* Cardium Richardsoni, N. Sp. Shell inflated, but not quite as 



thick as high, inequilateral; outline transversely and ovately subcircular. length 

 slightly exceeding the height; posterior side rather longer, and more narrowly 

 rounded than the anterior: beaks large, elevated, incurved and approximating; 

 placed a little in advance of the middle. Surface of the anterior and central por- 

 tions of the shell marked by flattened and comparatively broad, radiating ribs, 

 separated by narrower, deeply impressed lines, both of which are crossed by faint, 

 concentric striae or lines growth. On the posterior area, the radiating ribs are 

 thin, prominent, and much narrower than the flattened interspaees, and the con- 

 centric striations are developed into elevated, thin and crenulated laminar ridges # 

 Hinge with two small cardinal and two remote lateral teeth in each valve, one 

 of which is sublunular. Pallial line entire ; inferior margin of the valves dentic- 

 ulated all round within. Valves touching at all points when closed ; not open aj 

 either extremity. 



Length of th'j only specimen yet obtained, eight lines and a quarter : height 

 •even lines and a half; thickness through the closed valves, not quite six lines. 



Strait of Georgia, between Race Island Lighthouse and Victoria Harbour, in 

 30 to 50 fathoms.
