Anodonta angulata, Lea,+A. feminalis, Gd.  Plentiful in Yakima River, 
W.T., Cooper. A series of specimens of various 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. Trask. 
Cardium Nuttall, 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, ? from the sun’s heat.’ 
Cardium quadragenarium, Conr. One valye. San Luis Obispo, Dr. Antisell. 
Lucina Californica, Conr. San Diego, Cassidy. 
Cyclas, sp. nd. Whidby’s Island ; pools near Steilacoom, Cooper. 
Venus staminea, Cony.,+ Venerupis Petitii, Desh.,+ Venus rigida, Gld. [pars], 
+ Tapes diversa, Sby. Shoalwater Bay and Puget Sound, Cooper, Suck- 
ley; San Francisco, Trask; San Diego, Lieut. Trowbridge. [To the 
above synonymy, by Judge Cooper, the large series of specimens in the 
Smithsonian Mus. compels an assent. He considers Tapes straminea, of 
Sby. Thes., to be a variety of V. histrionica, but it more probably = 7. 
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; we may add also, of 
the pallial sinus. 
Saxidomus Nuttall [Coop., non} Conr.,+ Venerupis gigantea, Desh.,+ Venus 
maxima, Phil. [?}. Near Copalux River, south of Shoalwater Bay, com- 
mon at Puget Sound, Cooper; Bodegas, Cal., Trask. “Much superior to 
the Atlantic guahog as food, but called by the same name. Its station is in 
somewhat hard sand, near L-w. mark,” J. G. C. [Judge Cooper regards all 
the Saxidomi of the coast, except \S. avatus, as one species. The southern 
form, “with rough concentric strize and brown disc,” is Conrad’s species ; 
“others from Oregon are much smoother, without regular strie.” These are 
S. 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 yarical ridges, while the softer interstices have

Venus lamellifera, Conr.,= Venerupis Cordieri, Desh. San Diego, Cassidy. 
Lutraria maxima, Midd., = LZ. capax, Gld. [= Schizotherus Nuttalli, Conv.] 
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, 73 in. The burrows are found in the cliffs, 10 feet 
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, Suckley; San Francisco, Trask. 
Tellina edentula {Cpr., Coop., not Brod. and Sby.,=Macoma secta, var. edulis, 
Nutt.]. Puget Sound, Gbds. 
Tellina Bodegensis, Hids. Shoalwater Bay, rare, Cooper; mouth of Umpqua 
River, Vollum. 
Sanguinolaria Californiana, Cony. “Common at the mouth of the Columbia 
and other rivers, and high up salt-water creeks,’ Cooper. [= Macoma 
inconspicua, Brod. and Sby.]
