Subfamily HAUSTORIINAE 



Acanthohauatoriua intermediiu 

 Bousfield 1%5 



This 9p)ecies has been repwrted from Cape Cod Bay to 

 northern Florida on fine sands to 40 m (Bousfield 1973). 

 We collected A. intermedius at 17 stations between 

 Cape Cod and Cape Hatteras (Fig. 16). Its density at 

 these stations was low to moderate (2-170/m^) with a 

 mean of 30/m^ Our samples were rather evenly dis- 

 tributed between 7 and 40 m. All 17 stations were on 

 sand bottoms.

also occurred on sand-shell (1/36) and sand-gravel 

 (1/36). 



Acanthohaustoriua apinoaua 

 Bousfield 1%2 



This species has previously been collected between 

 Nova Scotia and the south side of Cape Cod on coarse 

 and medium sand to depths of 200 m (Bousfield 1973). 

 In our collections, A. spinosus occurred in low densities 

 (2-30/m^) at 14 stations between C&pe Cod and Cape 

 May, N.J. (Fig. 16). Acanthohaustorius spinosus was 

 found between 23 and 74 m, but occurred most fre- 

 quently (10/15) between 30 and 49 m. All the stations 

 were on sand bottoms. The eight records south of Long 

 Island extend the range of this species to the south. 



Acanthohaustorius sp. A 



This new species of Acanthohaustorius is currently 

 being described by Ann Frame of National Marine Fish- 

 eries Service (NMFS) Sandy Hook Laboratory, High- 

 lands, N.J. We collected single specimens of this sjjecies 

 from stations off New Jersey and Virginia in 20 and 23 m 

 on sand bottoms (Fig. 16). 



Acanthohaustorius sp. C 



An undescribed species of Acanthohaustorius was 

 found at 10 stations in our Middle Atlantic Bight collec- 

 tions (Fig. 16). The majority of the stations (8/10) were 

 located near the mouth of Chesapeake Bay. Its numeri- 

 cal density varied between A/m^ and 60/m^ with a mean 

 of 20/m^. We collected this species between 10 and 37 m 

 on sand (8/10) and shell (2/10) sediments. 



P€trahaustorius attenuatus Bousfield 1965 



Bousfield (1973) reported that this species has been 

 found from Georges Bank south to Chesapeake Bay on 

 clean sand to depths of >50 m. We collected this species 

 at 11 stations between Cape Cod and Virginia (Fig. 17). 

 The mean density of P. attenuatus was 30/m^ ranging 

 between 2/m^ and 170/m^ We found this species 

 between 12 and 74 m, but the majority of the collections 

 (8/11) were between 20 and 40 m. All our records of P. 

 attenuatus were irom sand bottoms. 



Parahaustorius holmesi Bousfield 1%5 



Acanthohaustorius sp. B 



Geographic Distribution. This species which is an off- 

 shore cognate of A. millsi is presently being described by 

 Ann Frame of the NMFS Sandy Hook Laboratory, 

 Highlands, N.J. We collected Acanthohaustorius sp. B 

 in 36 samples from 35 stations between Cape Cod and 

 Cape Hatteras (Fig. 16). This moderately abundant 

 species had a mean density of 80/m^, ranging between 

 2/m^ and l,000/m2. The abundance of this species 

 showed no evidence of latitudinal trends within our 

 study area. 



Bathymetric Distribution. We collected Acantho- 

 haustorius sp. B between 9 and 74 m. It occurred most 

 frequently (34/36), and in the highest densities (40- 

 140/m2) between 10 and 49 m (Table 30). The bathy- 

 metric distribution of this species showed no tendency 

 to change with latitude. 



Sediment Relationship. Acanthohaustorius sp. B was 

 most often associated with sand sediment (34/36), but 



This species has been collected between (ieorges Bank 

 and the mouth of the Chesap>eake on fine clean sand in 

 depths between 20 and 50 m (Bousfield 1973). In our col- 

 lections, P. holmesi occurred at three stations between 

 Cape Cod and Long Island (Fig. 17). The densities of 

 this species at these stations was low (8-40/m^). The sta- 

 tions occurred between 16 and 46 m on sand bottoms. 



Protohaustorius deichmannae Bousfield 1%5 



Geographic Distribution. This species has been 

 recorded from Maine to South Carolina (Bousfield 

 1973). We collected P. deichmannae at 34 stations 

 between Cape Cod and Cape Hatteras (Fig. 17). This 

 moderately abundant species had a mean density of 

 50/m^, ranging from 2/m^ to 270/m^. This warm-water 

 species occurred more frequently in the southern pwrtion 

 of our study area; i.e., southern New England (4/34), 

 New York Bight (11/34), and Chesapeake Bight (19/34). 



Bathymetric Distribution. Bousfield (1973) reported 

 that this species occurs subtidally to about 20 m. In our
