714 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



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 8. 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 algse ; Vine- 

 yard Sound and Quick's Hole, on algse, etc., in 4 to 12 fathoms. 



Fossil in the Post-Pliocene of Canada (Dawson as L. Peachii). 



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 o'r less bifid at the end.

 Europe. Vineyard Sound and Quick's Hole, 5 to 10 fathoms, on Phyl- 

 lophora, etc., not uncommon.

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 Sertularice and other hydroids, and 

 slender red algae, (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.
