204 BIOLOGICAL SURVEY OF 



and hard bottoms. It so happened that we did not find a 

 single specimen in all our first-year dredging. Stations : D 35, 

 36, 38, 39, 43, 56, 63, 71, 83. Reported from Eastport, Casco 

 Bay, deep waters of Massachusetts Bay (Couthouy), Cana- 

 dian coast, Hudson Strait, Labrador, Greenland. 



Aporrhaidae 



Aporrhais Dillwyn 



A. (Arrhoges) occiDEiSTTALis (Beck). {Rostellaria occiden- 

 talis Beck, 1836, Mag. de Zool. ; Aporrhais occidentalis Gould, 

 1870, Inv. Mass., p. 320, fig. 589.) But one specimen was 

 taken by us, just outside of Egg Rock. It would appear to 

 be a more outside form, for it is reported constantly from 

 deeper water and fisherman complain of its boring holes in 

 the fish that are caught in gill nets and reach the bottom, 

 and say that frequently fish are found with several of these 

 large red wounds on them. 



In the territory extending out from Gilpatrick's Ledge 

 at Northeast Harbor, between Greenings and Suttons Islands, 

 where the best mollusc ground is, Aporrhais is found abun- 

 dantly. This species has been identified as Aporrhais occi- 

 dentalis var. mainensis by C. W. Johnston, who has described 

 it in Nautilus. 



The record shows that this is the only place it has been 

 taken with the exception of the Isle of Shoals. This beautiful 

 animal is found here in great abundance in all sizes and a 

 series is shown in figure 38. We never dredged it at any 

 other place, and Blaney does not report this variety and 

 lists A. occidentalis as rare, and no specimens fully matured. 

 Nova Scotia, St. Lawrence, Labrador Atlantic coast, 10 to 60 

 fathoms ; fossil from Labrador. 



Muricidae 

 Trophon Montfort 

 T. TRUNCATus (Strom). (T. clathratus Gould, 1870. Inv. 

 Mass., p. 377, fig. 643.) Quite common, but in small numbers. 

 Stations : D 24, 25, 35, 36, 38, 103, 117. Reported from East- 

 port, Casco Bay, Annapolis Basin, Gaspe Bay, Halifax.
