"This great dam (as all these edible bivalves are indiscriminately called) is found in Shoal- 

 water bay, within a rather limited area near the mouth and along the larger channels. It is 

 buried near two feet deep in hard sand, near low water mark, its long siphon reaching the 

 surface and showing where it can be found. It also abounds in many parts of Puget Sound, up 

 to near Olympia. It is excellent as food, and has always been one of the chief articles of 

 winter stores to the Indians, who preserve the hard parts by stringing and then smoking them 

 in their lodges. It attains to 7| inches in breadth, and is very capacious. 



Portions of the clay and sandstone cliffs surrounding the bay are perforated by the burrows 

 of this animal at a height of ten feet above the present high water. All the other mollusca 

 inhabiting the bay now are also found in these fossil beds; and two which are not found 

 now were then common. There is no tradition among the Indians of the time of their elevation, 

 and the ancient trees standing on the surface show no signs of the irregular upheavings which 

 raised the former levels of low water, by successive stages, to a height now nearly one hundred 

 feet above the sea." — C.

 flai.— Shoalwater bay. Dr. Cooper ; Puget Sound, Dr. Suckley ; San Francisco, Dr. Trask. 



Rather a common species, whose range extends from Lower California to the Arctic regions, 

 having been found by Eschscholtz at Sitka, and by Middendorfi' in the Sea of Okhotsk. 



TELLINA EDENTULA. 



Tdlina edentuJa, Brod. & Sows. Zool. Journ. IV, p. 363.— Gray, Zool. of Beechey's Voy. p. 154,pl. 41, f. 5,and pi. 

 44, f. 7.— Carp. Rep. p. 301. 

 flbft.— Puget Sound, G. Gibbs; Oregon, Nuttall. 



Several specimens of this large species were sent to the Smithsonian Institution by Mr. 

 Gibbs. It was also found at the mouth of Columbia river by Mr. Nuttall. In old shells the 

 teeth nearly disappear, but in younger examples they arc long and strong, so that the name is 

 not strictly applicable. 



TELLINA BODEGENSIS. 



Tdlina hodegensis. Hinds, Zool. Voy. Sulph. p. 67, pi. 21, f. 2.— Carp. Rep. p. 302. 

 i7aA.— Shoalwater bay. Dr. Cooper ; mouth of the Umpqua river. Dr. Vollum, U. S. A. 



This is much more rare than T. nasuta found in the same stations.
