DISTRIBUTION OF BRITISH ECHINODERMS. 187 
So far as at present known 56 species are found in the Faeroe 
Channel, of which 25 are not known in the seas nearer Britain ; of 
the 43 found at Shetland only 3 have not been collected further 
south. The record of Channel Islands species ought, in all proba- 
bility, to be a good deal higher than 22; of these, only one (Spher- 
echinus granularis) is not found to the northward of those islands. 
Forty-four species are recorded from the North Sea, but the east 
coast of England would seem to be particularly poor, if we may 
form an opinion from tbe Collections in Museums.
