Table II. — Sjiecies not Jcnovjn beyond the British Area. 



Of these species twenty-five are known only from the neighbour- 

 hood of our own shores ; they fall into one of three categories. 



(1) Littoral and rare or very local. 



1. Hotothuria nigra: Canon Norman, whose opinion on British forms 



must always he most respectfully considered, is inclined to think 

 this is the same as a Mediterranean species. 



2. Asterias murrayi, which is, I think, with our present lights, a good 



species. 



3. A. hispida : this is a very difficult form to recognize, and one is often 



inclined to regard it as the young only of some commoner form.
