The “sand collars” of this and the preceding 
species are cast up on the beaches throughout 
the summer. They are likewise frequently 
dredged in Vineyard Sound. 
This and the preceding species feed upon various 
mollusks, whose shells they perforate by means 
of the lingual ribbon. 
Polynices triseriata (Say). [Chart 188.] 
Gould, 1870, p. 340 ( Lunatia triseriata)-, Verrill, 
1872, p. 282 ( Lunatia heros, var. triseriata)-, Ver- 
rill and Smith, 1873, p. 646, 354, etc. ( Luna- 
tia heros, var. triseriata)-, Dali, 1889, p. 154 
{Lunatia heros, var. triseriata. — Dr. Dali now 
regards this as a true species). 
Abundant and of pretty general distribution, 
both in Vineyard Sound and Buzzards Bay; 
far commoner in the latter than P. heros, but 
somewhat less frequent in the former. — Sur- 
vey. Living specimens dredged in 1 to 12 
fathoms, on various bottoms, including muddy 
ones; shells widely distributed by hermit 
crabs. Verrill ’s statement that this “variety ” 
“is the more common form in the deeper 
waters” (i. e. commoner than P. heros) does 
not hold for the region dredged.

a See note under Polynices heros. Certain records for the latter perhaps apply to the present species. The converse is not 
believed to be true.
