cal areas throughout much of the study area (Fig. 105). 

 They were most common in the Nova Scotia region, the 

 periphery of the Gulf of Maine, in deep water south of 

 Georges Bank, and on the outer shelf south of Cape 

 Cod, Massachusetts. They were notably absent in the 

 Georges Bank-Nantucket Shoals area and in deep water 

 in the western Gulf of Maine. In all but a few locations 



their numerical density was less than 9/m 2 and their 

 weight averaged less than 1 g/m 2 . 



Three of the six standard geographic areas contained 

 significant quantities of chitons: Nova Scotia, Gulf of 

 Maine, and the Southern New England Shelf (Tables 6, 

 8; Fig. 106). The average number of specimens ranged 

 from 0.9 to 3.6/m 2 . Average biomass was small, 0.24 g/m 2
