WEST COAST SHELLS 



lunule, in this species, belongs wholly to the right 

 valve, instead of being divided nearly equally be- 

 tween the two, which is the more common fashion. 

 As in other species of this genus the forward muscle- 

 scar is long and narrow, and the pallial line is entire. 

 I have gathered a few living specimens from the 

 gravel among rocks at Pacific Grove, when the tide 

 was very low, and have collected many empty, but 

 really good shells that have been cast up by the 

 waves. It is one of the shells that you will be sure 

 to find on the little beaches beyond the lighthouse 

 at Point Pinos, near which, from the island cliifs, 

 there is one of the finest sea views to be had any-

Phacoides nuttallii, Conr., Nuttall's Lucine, is 

 similar in shape to the last species, but is much more 

 highly sculptured. The sharp, fine lines of growth 

 are crossed by many delicate rays, making its surface 

 look like fine basket-work. It is somewhat flattened 

 and is ridged along the hinge-line. Color white, 

 length an inch or less, southern. 



In Figure 44 we 

 see a drawing of the 

 inside of a valve of 

 Phacoides annula- 

 tus^ Reeve, the 

 Ringed Lucine. It 

 is a large shell, and 

 it ranges from Sitka 

 to San Pedro, living 

 in moderately deep
