CORYNACTES. 227 
1. Capnga sancuinga, Ff. Forbes. 
Hab. Deep water, Isle of Man, Prof. E. Forbes; Fal- 
mouth, on a valve of Pecten maximus, W.P. Cocks. 
A good description and characteristic figure (fig. 43) of 
it are given in Dr. Johnston’s ‘ History,’ by Professor E. 
Forbes, who discovered it. When expanded, it is about 
an inch in height and one-fourth of an inch broad. ‘The 
colour is vermilion. It is rather an active creature, chang- 
ing its form often, but always presenting more or less of a 
tubular shape, like a chimney-crock, or steam-boat funnel. 
It takes its name from a Greek word signifymg a chim- 
ney. The shape of the tentacula, which are like the embra- 
sures on the top of a turret, and a brown woolly epider- 
mis, distinguish it from all others of the tribe to which it 
belongs.
