 Observed in act of depositing eggs in latter part 

 of July and early August; probably breeds all 

 summer. G. A. Drew.

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 i 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."
