Observed in act of depositing eggs in latter part 
of July and early August; probably breeds all

Abundant throughout the Sound, and common 
at the inshore stations and lower end of the 
Bay; almost wholly absent from the deeper 
waters of the latter ; recorded from Crab Ledge ; 
living specimens dredged in 1 to 19 fathoms, 
predominantly on bottoms free from mud; 
shells more generally distributed. — Survey. 
The living specimens taken during the Survey 
dredging were all or nearly all small; shells of 
large size were frequently taken, however. 
Mr. Gray reports that half-grown living speci- 
mens are to be found on Devils Foot Island, 
and at Falmouth Heights, no full-grown speci- 
mens having been taken by him in this region. 
According to Verrill, “its proper home is on 
sandy bottoms in shallow water, just beyond 
low- water mark and down to the depth of 4 or 
5 fathoms. ”
