Macoma balthica (Linnaeus). 
Gould, 1870, p. 93 ( Macoma fusca; not listed 
for this region); Verrill and Smith, 1873, p. 
676, 359, etc. (Macoma fragilis and M. fusca.) 
Wareham River, shallow water at low tide. — 
Cole. Nonamesset Island, 1 shell. — Osburn. 
Tisbury Great Pond, perhaps common (sev- 
eral living specimens collected by Mr. Ed- 
wards). Not recorded among the shells taken 
by the dredge. Common, according to Ver- 
rill, on muddy shores, between tides. 
Verrill states that two varieties, fusca and fra- 
gilis, are taken together, which, in this region, 
grade insensibly into each other. 
? Macoma calcarea (Gmelin). 
Verrill and Smith, 1873, p. 677 ( Macoma sabu- 
losa) . 
No definite local records, though this region is 
included within range of the species as stated. 
Family SolLniDv®. 
Siliqua costata (Gould). 
Verrill and Smith, 1873, p. 675, 358, etc.; Dali, 
1889, p. 70. 
Vineyard Sound, sandy shores and bottoms. — 
Verrill. One young specimen (shell or liv- 
ing ?) recorded by tire Survey from Fish Hawk 
station 7685*, at mouth of Vineyard Sound, in 
17 fathoms. 
Ensis directus Conrad. Razor clam, razor shell, 
razor fish. [Chart 15 1.] 
Gould, 1870, p. 40 ( Solen ensis); Verrill and 
Smith, 1873, p. 674, 356, etc. (Ensatella 
americana); Dali, 1889, p. 72 (Ensis americana); 
Mead, 1898 (Solen ensis). 
Shells abundant throughout both Sound and 
Bay, in 2 to 19 fathoms, on bottoms of every 
kind; living specimens abundant in the Bay, 
in 2 to 8 fathoms, chiefly on bottoms of muddy 
sand and sandy mud, scarcely ever dredged in 
the Sound. — Survey. This species is also lit- 
toral and adlittoral in its habitat, forming deep 
burrows in the sand. Large living specimens 
reported by Osburn in a sand flat near entrance 
of Lagoon Pond ; probably common in all sim- 
ilar localities.
