Placunenomia macroschisma Deshayes. 



Plate III, fig. 75. 



This species is quite general along the coast. 



Mytilus californicus Conrad. 

 Plate I, figs. 13a, &. 



This species is the most abundant shell-fish on the coast. 



It lives on the rocks at tide-line, and the rocks are completely 



covered with its representatives. They stick to the rocks so 



tightly that it is with difficulty that they are pulled from their 



lodgement. It is this "mussel" that the Indians are so fond 



of. They gather them by the basketful, put them, shell and 



all, into a pot and boil them. Then the "mussel" meat is 



scraped from the shell and eaten. They also eat them raw; 



also, bake them — that is, they dig a pit, throw hot rocks into 



it, then put the clams on the heated rocks, and cover the rocks 



and "mussels" up with dirt. These they leave till the next 



day. The "mussels" are then dug up and make excellent 



eating. 



Pholadidea ovoidea Gould. 

 Plate I, figs. 5a, h. 



The shell of this species is very frail and easily broken. 

 Only one whole valve was seen. The species is not numerous.
