 \V. T., C'oopfii: A series of spccMniens of various ages leads Judge Cooper 

 to indorse Dr. Lea's ojiinion of the identity of the two species.

 382. Cardium Xii'tdJIi, Conr. Shoalwater Bay ard Puget Sound, Cooper; San 

 Franc, Dr. Bii/elow, Trunk. "The most abundant clam of Shoalwater Bay, 

 inhabiting sandy mud, a few inches below the surface. The Indians feel 

 for them witli a knife or sharp stick ■w4th great expertness. In July many 

 come to the surface and die, .''from the sun's heat.'

 lei/ : San Francisco, Trask ; San Diego, Lieut. Trou'hrid(/e. [To the 

 above sj-nonjnny, by Judge Cooper, the large series of specimens in the 

 Smithsonian Mus. compels an assent. lie considers Tapes straminea, of 

 Sby. Thes., to be a variety of V. histrioniea, but it more probably = T. 

 f/rata, as Dr. (Joiild appears to have considered it, having copied Sowerby's 

 error. Conrad named it, not from the colour, as was supposed when quoting 

 it as " sframinea," but from the thread-like sculpture (test« Conr. ips.). 

 AVhatever be t!ie firm, colour, or sculpture of the shell, Judge Cooper 

 Ti'miirks in all the same characters of teeth and hinge ; we may add also, of 

 the pallial sinus.] 

 SS3. Sruidomus Nuttalhi [Coop.,non] Conr.,-^Venentpis (jigantea, Desh..+ Vemts 

 maxima, Phil. [?]. Near Copalux River, south of Shoalwater Bay, com- 

 mon at Puget Sound, Cooper : Bodegas, Cal., Trask. "Much superior to 

 the Atlantic quahorj as food, but called by the same name. Its station is in 

 somewhat hard sand, near l.-w. mark," 7. G. C. [Judge Cooper regards all 

 the Saxidomi of the coast, except S. aratus, as one species. The southern 

 fonn, "with rough concentric striae and brown disc, ' is Conrad's speciis; 

 "others from Oregon are much smoother, without regular stri;e. ' These are 

 S. sqnalidus, Desh. Dr. Cooper found " a fossil variety, in const-banks 10 

 feet above sea-level, which is well tigured in Midd. and (less distinctly) by 

 Desh. A Califoniian specimen measures 48 in. across." The fossils, through 

 disintegi-ation, often assume the aspect of Venus Kennerlei/i, the former 

 margins remaining as varical ridges, while the softer interstices have 

 perished.l

 Shoalwater Bay, Cooper. San Francisco, Trask. " Lives buried nearly 2 feet 

 in hard sand, near 1. w. mark, its long siphons reiiching the surface; also in 

 many parts of Puget Sound up to near Olympia. It is excellent food, and 

 a chiet article of winter stores to the Indians, who string and smoke them 

 in their lodges. Length, 7| in. The buiTows are foimd in the cliffs, 10 feet 

 above high water, with all the other MoUusca now living ; and two, not 

 now found, were then common [viz. ?. . .]. The Indians have no tradition 

 as to the elevation, and the ancient trees show no signs of the irregular 

 upheavings which raised the former levels of low water, by successive 

 stages, to a height now nearly 100 feet," J. G. C.
