196 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [490] 
megalophthalma (p. 336) are everywhere common, burrowing in the sand. 
The Cancer irroratus (p.338) and Platyonichus ocellatus (p. 338) are rather 
common at and just below low-water mark. The Hippa talpoida (p. 338, 
Plate UU, fig. 5) is occasionally found, and the young sometimes occur 
in. large numbers, burrowing in the sand at low-water mark. The com- 
mon shrimp, Crangon vulgaris, (p. 339, Plate IL, fig. 13 is usually abund- 
ant where there are sheltered sandy flats. 
The Annelids are less numerous than on the sandy shores of the 
sounds, but such as do occur are mostly of the same species. One of 
the most interesting is the Nerine agilis, (p. 546,) which is very remark- 
able for the rapidity with which it burrows in the sand. 
The Mollusks are few in number. One of the most abundant of the 
Gastropods is the Lunatia heros, (p. 303, Plate XXIII, figs. 133-136,) 
which burrows just beneath the surface of the sand, at and below low- 
water mark. The Neverita duplicata (p. 354, Plate X XIII, fig. 130) is 
also occasionally found, but is much less abundant than in the bays. 
Of Lamellibranchs there are but few species that can maintain them- 
selves in such situations. Among these the “long clam,” Mya arenaria, 
(p. 463,) the “ razor-shell,” Hnsatella Americana, (p. 356,) and the “ surf- 
clam,” Mactra solidissima, (p. 358,) are the most common. 
Very few, if any, Radiates are to be found on the exposed sandy shores, 
unless thrown up by the waves from deeper water. In places that are 
somewhat protected from the violence of the surf, the Leptosynapta Gi- 
rardit (p. 361, Plate XX XV, figs. 265, 266) is often found burrowing in 
the sand at low-water mark. Sometimes, in similar places, the ‘“ sand- 
dollar,” Echinarachnius parma, (p. 362, Plate XX XV, fig. 267,) is found 
in large numbers at extreme low-water mark. 
There are no Hydroids and Polyps that properly inhabit such shores.
