VENERIDA 
Genus Paphia Bolten 
Paphia (Protothaca) grata Sby. 
Some years ago I collected one shell of this species in the 
drift at Terminal Island. Identified by Dr. Wm. H. Dall, U.S. 
Nat. Mus. ‘‘Synopsis of the Veneridz’’ Wm. Healey Dall, (Proce. 
U.S. Nat. Mus. Vol, XX V1), page 397. 
Dr. R. E. C. Stearns considers the common Redondo form of 
Paphia (Tapes), the northern ue of grata rather than the 
southern of staminea. 
TELLINIDA 
Genus Macoma Leach 
Macoma undulata Hanley. 
Young specimen, drift at Terminal Is. presumed by Dr. Dall 
to be this species, too young to be sure., ‘‘Synopsis of the Fam- 
ily Tellinide and of the North American Species’’ Wm Healey 
Dall, (Proe. U. S: Nat. Maus: Vol XEXTIT) page 309: 
Semele incongrua Cpr. 
Dredged San Diego Bay in 1899 by Prof. F. W. Kelsey. In 
Die, di, Ge. Cooper’ s Geog. Cat. of Moll.; ““Catalina Id. 16 to 20 
fathoms, rare.’ 
CORBULIDA 
Genus Corbula Bruguiére 
Corbula luteola var. rosea var noy. 
Valve on anemone in a rock pool on the old breakwater at 
Terminal Island. 
As the name would indicate Corbula luteola is yellowish. But 
the disk of this variety is of a bright pink—lke a brillant 
Telline carpenteri Dall—excepting a ray of white from the 
beak across the umbonal portion; around the hinge area and 
the ventral margin the color is of a rosy flesh color; the interior 
of the valve is pink. The surface is sculptured with the same 
concentric lines as in the type. For a description and figure of 
typical luteola see Dr. Ralph Arnold’s comprehensive volume 
upon our West Coast Mollusca under the title ‘‘Memoirs Cal. 
Aead. Sciences Vol. I[1[—the Paleontology and Stratigraphy of 
the Marine Pliocene and Pliestocene of San Pedro,’’ page 181, 
plate XVII, fig. 11, and ‘‘West American Shells’? by Josiah 
Keep, A. M., page 87.
