42() REPORT OF COMMISSIONER OF FISH AND FISHERIES. [714] 
some specimens a few of the cells have several slender spines around 
the margin of the aperture. 
This may prove to be a species distinct from S. Pallasiana, but at 
present I regard it as a variety.

Long Island Sound, northward; northern coasts of Europe to Great 
Britain. Watch Hill, Rhode Island, 4 to 5 fathoms, on red alge; Vine- 
yard Sound and Quick’s Hole, on alge, ete., in 4 to 12 fathoms. 
Fossil in the Post-Pliocene of Canada (Dawson as L. Peachit). 
The specimens from our coast, referred to the above species, differ 
considerably from the typical European forms, and may eventually 
prove to be a distinct species when a careful direct comparison with a 
large series of European specimens can be made. 
The aperture is usually surrounded by a circle of stout, conical or 
elongated spinules, variable in number, the one nearest the angle of the 
aperture, on each side, often stouter; but the spines are often absent. 
A small semicircular avicularium is often seen near one.side of the cell, 
and distant from the aperture. The tooth or spine at the proximal edge 
of the cell is elongated and more or less bifid at the end.

Long Island Sound to Greenland; Spitzbergen; northern coasts of 
Europe to Great Britain. Very common near New Haven, off South 
End, at Thimble Islands, and Faulkner’s Island, in large tide-pools, 
low-water to 8 fathoms, chiefly on Sertularie and other hydroids, and 
slender red alge, (mostly the variety tuberosa, or verrucosa); Watch 
Hill, Rhode Island, 4 to 5 fathoms; Buzzard’s Bay and Vineyard 
Sound, 1 to 15 fathoms, on hydroids, common; abundant in Casco Bay; 
Bay of Fundy; and at Saint George’s Bank ; low-water to 145 fathoms.
