WEST COAST SHELLS 



'T'ellina salnionea^ Cpr., the Salmon-colored Tel- 

 len, is a very distinct little species, variable in color, 

 but constant in form. The typical shell is quite

 and glossy, but shows distinct lines of growth. It 

 is nearly white on the outside, but within it is beau-

 the smaller beach shells at Pacitic Grove.

 is thinner, flatter, and 

 has different details of 

 sculpturing. It is found 

 near the Santa Barbara 

 Fig. 71, X a*) Islands. 



At various points around San Francisco Bay there 

 are great heaps of rubbish, which mark the site of

 which is now indicated by a growth of willows. 

 The mounds are of various shapes and sizes, and 

 often cover as much ground as would suffice for a 

 good-sized garden. These mounds are largely made 

 up of old shells, ashes and charcoal dust. This 

 shows that the Indians had their fires there, and that 

 they threw away the rubbish which was left from
