(i fragment), 161 (i fragment), 163 (i shell), 

 164 (2 shells), 165 (2 shells). 

 Gonads ripe, commencing middle of June; veli- 

 gers noted latter part of August and early Sep- 

 tember; young i mm. in length taken off 

 Nobska Point, September 20. M. T. Thomp- 

 son. 



This valuable mollusk is entirely neglected on 

 our shores; in some parts of Europe it forms 

 an important item of food. 



Lacuna puteola Turton. [Chart 181.] 



Vineyard Sound, abundant, chiefly at the in- 

 shore stations; in Buzzards Bay almost wholly 

 confined to the neighborhood of the Elizabeth 

 Islands; dredged in i to 17 fathoms, chiefly 

 3.1 depths less than 8 fathoms, and almost ex- 

 clusively on non-muddy bottoms. Survey. 

 This species is often associated with Astyris 

 lunata.

 1889, p. 146. 



Vineyard Sound and Buzzards Bay, Sheep Pen 

 Cove, Tarpaulin Cove, Cedar Tree Neck, Gay 

 Head, Sow and Pigs Reef. Found among 

 algae and eelgrass near low- water mark. Ver- 

 rill states that this species occurs at depths of 

 4 or 5 fathoms, but this is certainly not usual 

 locally, for it was recorded from only four of the 

 survey dredging stations. 



Lacuna vincta Continued. 



Fish Hawk station 7557 bis; Blue Wing stations: 

 47 and 51; Phalarope station in. 



Taken in the act of spawning during February 

 and March; the eggs have likewise been found 

 December 10. These are inclosed in ring- 

 shaped masses of jelly, commonly having a 

 somewhat greenish tint. Edwards, Sumner. 



Lacuna sp. (undetermined). 



Fish Hawk stations: 7721 (young), 7725.

 within the stated range of the species.

" Brackish and muddy shores of ... Buzzards 

 Bay, Vineyard Sound . . ."-Verrill. South 

 arm of West Falmouth Harbor, between tides. 

 (Collected by Cole, identified by Dall and 

 Bartsch.) Dredged in Vineyard Sound, at 

 Fish Hawk station 7550 bis (probably an empty 

 shell). 



Verrill states that this species forms much of the 

 food of certain small fishes and aquatic birds.
