BIOLOGICAL SURVEY OF WOODS HOLE AND VICINITY. Ler 
stations in Buzzards Bay. The latter list is seen to be the most extensive one, so far 
as annelids are concerned. It will be found upon p. 66 and need not be repeated here. 
Distribution charts (54-82) have been prepared for those 29 species (exclusive of 
Spirorbis) which were taken at 10 or more dredging stations. With respect to their 
distribution in local waters, we may arrange the species in the five following groups: 
Species nearly or quite restricted to Vineyard Sound.

These species and some less frequent ones which might have been included are 
recorded almost exclusively from bottoms of sand or gravel. It is perhaps worth noting 
that the three listed are ones which are found most commonly in the interstices of the 
sandy ascidian, Amaroucium pellucidum. Polycirrus eximeus is recorded by us only 
from the eastern half of the Sound. 
Species occurring predominantly in Vineyard Sound, though more or less common in Buzzards Bay.

Reference to the charts shows that in the case of four of these six species, their 
occurrence in Buzzards Bay is in a large degree restricted to the inshore stations. This 
is a type of distribution which has been met with frequently, being exemplified by 
animals belonging to nearly all phyla. The comparative scarcity of mud at these 
inshore stations of the Bay is doubtless responsible for this peculiarity in their distri- 
bution.
