This species is found abundantly in the British and Medi- 
terranean seas in very deep water on sandy bottoms, Plymouth 
Sound, Torbay, Falmouth, Penzance, Friths of Forth and Clyde, 
Cork Bay, Bantry Bay, Dingle Bay and Salcombe Bay. 
The ribs of the young shells are angular, and farther apart 
from each other; and the spines are sharper and much longer 
proportionally than in the adults. 
The animal is pale flesh-coloured, sometimes slightly testace- 
ous; the respiratory tubes are ciliated ; the cilia nearest to the 
apertures flesh-coloured, and sometimes, but rarely, pale tes- 
taceous ; the foot very long, cinnabar red, its base paler.

yellowish-brown, banded and spotted with chestnut-brown, the 
inferior and hinder aspects chestnut-brown, about the umbones 
milk-white. Length and height three inches and a quarter.
