Mexico (Bousfield 1973). In our collections, M. nitida 

 occurred in low to moderate densities (10-260/01^) at sta- 

 tions in the Hudson River, off Staten Island, and in the 

 upper Chesapeake Bay (Fig. 14). The depth at these sta- 

 tions ranged between 8 and 16 m, and the sediment 

 types represented were sand, shelly silt-clay, and silt- 

 clay. 



Melita sp. A 



An undescribed species of the genus Melita was col- 

 lected in 13 samples from 12 stations between Cape Cod 

 and New Jersey (Fig. 14). The density of this species was 

 low (2-20/m^) at all stations. It was rather evenly dis- 

 tributed between 68 and 97 m. These samples occurred 

 on sand (9/13), silty sand (3/13), and shell (1/13) bot- 

 toms. 



Family HAUSTORimAE 



Subfamily PONTOPOREIINAE 



Amphiporeia gigantea Bousfield 1973 



Bousfield (1973) found this species between Cape Cod 

 and Sauidy Hook, N.J., on stmd bottoms in 10-15 m. We 



collected two specimens of A. gigantea at a single sta- 

 tion southeast of Nantucket in 37 m on a sand bottom 



(Fig. 15). 



Bathyporeia parkeri Bousfield 1973 



According to Bousfield (1973), this species occurs 

 from the south side of Cape Cod to northern Florida on 

 exposed sand beaches to 10 m depth. We collected this 

 species at six stations between Cape Cod and Virginia 

 (Fig. 15). Bathyporeia parkeri occurred in low densities 

 (2-6/m2) at all these stations. Our collections were 

 slightly deeper than Bousfield's, from 20 to 30 m, and all 

 the stations were on sand bottoms. 



Bathyporeia quoddyensis 

 Shoemaker 1949 



This species has been collected between Nova Scotia 

 and Chesapeake Bay on fine sand to 40 m (Bousfield 

 1973). Bathyporeia quaddyensis occurred at 10 stations 

 between Cape Cod and Virginia in our collections (Fig. 

 15). The density of this sf)ecies was low (2-30/m^) except 

 for a single station off Nemtucket where a density of 

 900/m2 occurred. The collections of this species were 

 made between 13 and 30 m on sand sediments.
