Distribution probably very general throughout 

 the muddy shores and shallow waters of the 

 region. Extremely abundant at certain points 

 such as the Eel Pond, Great Pond, Wareham 

 River, etc., and perfectly at home in waters 

 which are decidedly brackish. Owing to its 

 littoral habitat it was rarely taken during the 

 survey dredging, except at stations close to 

 shore. In deeper waters dead shells were oc- 

 casionally met with, these having probably 

 been transported by hermit crabs.

Eggs noted by A. D. Mead April 25 and 27. 



Arcularia vibex (Say).

 region), Verrill and Smith, 1873, p. 640, 371,

New Bedford. Adams. "Northward to Vine- 

 yard Sound," where it is "found sparingly in 

 shallow water among eelgrass. ' ' Verrill. Ware- 

 ham River and a few other points in Buzzards 

 Bay, 2 to 4 fathoms, mud. Survey. 



Phalarope stations: 153 (i shell), 155 (several 

 living), 157 (i small shell), 163 (i)*. 



Family COI^UMBELUD^. 



Anachis avara (Say). [Chart 169.] 



Gould, 1870, p. 350 (Columbella a-vara); Verrill 

 and Smith, 1873, p. 643, 306, etc.; Verrill, 

 i882d, < p. 371; 1884, Dall, 1889, p. 116. 



Shells generally distributed and of great abund- 

 ance in both Vineyard Sound and Buzzards 

 Bay, dredged in from i to 19 fathoms, on every 

 sort of bottom; living specimens abundant 

 throughout the Sound and along the eastern 

 shore of the Bay; rarely recorded from the 

 deeper portions of the latter. Survey. The 

 shells of this species are widely transported by 

 the smaller hermit crabs, probably being the 

 ones most commonly chosen by P. annuities.
