presents a greater diversity of conditions than that of the latter, rendering it a fit habi- 
tation for a greater variety of life. Such a view is in no way inconsistent with the 
supposition that the number of species per unit area is as great, or even greater, in 
Buzzards Bay. This matter will be referred to later.

5. EXPLANATION OF THE FAUNAL CATALOGUE. 
Part 1 of the present work consists of a catalogue or annotated list of the fauna 
of the Woods Hole region. The extent of territory comprised within the limits of the 
“Woods Hole Region,” as here conceived, has already been indicated in chapter I, of 
the present volume, where we have likewise discussed the sources of information upon 
which the present catalogue is based. 
It is true that an insignificant proportion, numerically considered, of those who fre- 
quent the laboratories at Woods Hole at the present time are interested primarily in 
systematic zoology or botany. But every working biologist, whatever his specialty,
