381. Anodonta angulata, Lea,+A feminalis, Old. Plentiful in Yaldma Hirer, 



W. T., Cooper. A series of specimens of var'ous ages leads Judge Cooper 

 to endorse Dr. Lea's opinion of the identity of the two species. 



Anodonta Oregonensis, Lea. Rivers of W. T., Cooper. 



Anodonta Wahlamatensis, Lea. Lagoons in Sacramento River, Dr. Trash. 



382. Cardium Nuttalli, Conr. Shoalwater Bay and Puget Sound, Cooper; San 



Franc., Dr. Bigelow, Trask. "The most abundant clam of Shoalwater Bay, 

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

 for them with a knife or sharp stick with great expertness. In July many 

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



Cardium quadragenarium, Conr. One valve. San Luis Obispo, Dr. Antisell. 



Lucina Calif arnica, Conr. San Diego, Cassidy. 



)} Cyclas, sp. ind. Whidby's Island ; pools near Steilacoom, Cooper. 



Venu^ staminea, Conr.,+ Venerupis Petitii, Desh.,+ Venus rigida, Old. [pars], 

 + Tapes diversa, Sby. Shoalwater Bay and Puget Sound, Cooper, Suck- 

 ley ; San Francisco, Trask ; San Diego, Lieut. Trowbridgc. [To the 

 above synonymy, by Judge Cooper, the large series of specimens in the 

 Smithsonian Mus. compels an assent. He considers Tapes straminca, of 

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

 grata, as Dr. Gould appears to have considered it, having copied Sowerby's 

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

 it as " straminea" but from the thread-like sculpture (teste Conr. ips.). 

 Whatever be the form, colour, or sculpture of the shell, Judge Cooper 

 remarks in all the same characters of teeth and hinge j we may add also, of 

 the pallial sinus.] 



883. Saxidomus Nuttallii [Coop., non] Conr.,+ Venerupis gigantea, Desh.,-f Vemts 



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

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

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

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

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

 form, " with rough concentric striae and brown disc, is Conrad's species ; 

 " others from Oregon are much smoother, without regular stri;e." The.-e are 

 & squalidus, Desh. Dr. Cooper found " a fossil variety, in coast-banks 10 

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

 Desh. A Californian specimen measures 4-8 in. across. " The fossils, through 

 disintegration, often assume the aspect of Venus Kennerleyi, the former 

 margins remaining as varical ridges, while the softer interstices have 

 perished.] 

 Venus lamellifera, Conr.,= Venerupis Cordieri, Desh. San Diego, Cassidy, 



884. Lutraria maxima, Midd., L. capax, Gld. [ = Schizotheerus Nuttalli, Conr.] 



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

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

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

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

 in their lodges. Length, 7f in. The burrows are found in the cliffs, 10 fert 

 above high water, with all the other Mollusca 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. 



Tellina nasuta, Conr. Common, from L. Cal. to the Arctic Seas. Shoal- 

 water Bay, Cooper-, Puget Sound, SucJdcy; San Francisco, Trask. 



Tellina edentula [Cpr., Coop., not Brod. and S\>y., = Macoma secta, var. edulis, 

 Nutt,]. Puget Sound, Gibbs. 



Tellina Bodegensis, lids. Shoalwater Bay, rare, Cooper; mouth of Umpqua 



River, Vollum. 



885. Sanguinolaria Californiana, Conr. "Common at the mouth of the Columbia 

 and other rivers, and high up salt-water creeks/' Cooper. \_ = 

 inconspicua } Brod. and Sby.]
