OYSTERS AND SMALL CLAMS 57 
I have gathered a few 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 had been cast up by the 
waves. It is one of the shells which you will be 
sure to find on the little beaches beyond the light- 
house at Point Pinos, where, from the island cliffs, 
there is one of the finest sea views to be had any- 
where along the coast. 
Phacoides nuttallu, Conr., Nuttall’s Phacoides, 
(Lucina nuttallii), 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 ridged 
along the hinge-line. Color white, length an inch 
or less, southern. 
In Figure 43 we 
see a drawing of 
the’ inside of a 
valve of Phacoides 
annulatus, Rve., 
the ringed Phacot- 
des, a large shell, 
which ranges from 
Sitka to San Pe- 
dro, living in mod- 
erately deep water. 
This is the species 
formerly known on this coast as Lucina borealis, 
and sometimes as L. filosa, Stimp., which, how-
