Quantitative Table No. 4. 
BOULDER-PAVED SHORES. 
The habitats listed in this table, eleven in number, are 
all bouldery and are on more or less exposed shores where 
the waves exert a marked influence. The water is from 1-3 
feet in depth. One habitat (X XV) supports 51 individuals 
of 8 species. The relation of this community to the bottom 
is expressed in Figure 32. The bivalves (1, 2, 3, 4) are seen 
to live in the sand between the stones, while the gastropods 
live for the most part on the stones. Gonzobasts is almost
