widened in front, and then distinctly contracted or notched 
behind the outer orbital angles. 
A small species widely distributed. Mr. Barlee found it 
in Shetland ; and it occurs in most parts of the coasts of 
England, Ireland, and Scotland. The Rev. Alfred TN T orman 
has supplied me with the following note : — “ Abundant, and 
very fine off the Isles of Arran and Cumbrae in the Eirfh 
of Clyde, and at Oban. It inhabits the coralline zone. 
This species varies very greatly in size in different localities. 
The following is a comparison of specimens taken at Sand- 
gate, as given by Mr. Bell and others, from the Moray 
Eirth, given me by Mr. Gordon, with these from Cumbrae, 
Sand- 
Moray Firth.

I have likewise taken it at Ealmouth. Mr. R. Couch in- 
forms me that it is not common on the Cornish coast, and 
that the specimens are always of small size there.”
