 647, 417, etc.; Ball, 1889, p. 154. 



" Vineyard Sound and Buzzards Bay . . . com- 

 mon in 2 to 10 f a thorns."- Verrill. Chiefly 

 recorded from inshore stations of Buzzards 

 Bay. Survey. Dredged in 2 to 7 fathoms (in 

 one case 17 fathoms), on quite various bottoms. 



Fish Hawk stations: 7550 bis*, 7563 bis*, 7611*, 

 7633 ( ? ). 7634 (?). 7777*: likewise at a 1907 

 repetition of 7624*.

Natica clausa Broderip & Sowerby. 

 Gould, 1870, p. 342 (not listed for this region); 



Verrill and Smith, 1873, p. 647. 

 "One small dead specimen . . . dredged . . . 

 in 19 fathoms, off Gay Head"; no record of 

 living specimens south of Cape Cod. Verrill. 



Polynices duplicata (Say). [Chart 186.] 



Gould, 1870, p. 345 (Neverita duplicata); Verrill 

 and Smith, 1873, p. 646, 354, etc. (Neverita 

 duplicata); Dall, 1889, p. 154 (Neverita dupli- 

 cata). 



Fairly abundant and of general distribution both 

 in Buzzards Bay and Vineyard Sound, from 

 low- water mark down. Living specimens 

 occasionally dredged at 2 to 8 fathoms; shells 

 much more common and occurring at all 

 depths, being frequently occupied by hermit 

 crabs. Verrill 's statement that this species is 

 "generally much more abundant [than P. 



o- Owing to a confusion which was at first made between this species and certain other small Naticidae, some of the records 

 here given are not wholly trustworthy. Specimens from the starred stations, on the other hand, were referred to Messrs. Dall 

 and Bartsch.
