(i fragment), 161 (i fragment), 163 (1 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 1 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 1 to 17 fathoms, chiefly 
at depths less than 8 fathoms, and almost ex- 
clusively on non-muddy bottoms. — Survey. 
This species is often associated with Astyris 
lunata.

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.

(Collected by Cole, identified by Dali and
