found on the South Coast of Devonshire.

whose body is only three-eighths of an inch diameter, has the 
arms seven inches in length, which is more than eighteen diame- 
ters of the body ; a disproportion not before noticed in any spe- 
cies of Asterias. 
This extraordinary animal is taken in sand at one particular 
part of Salcomb bay, where that article is collected for manure. 
The only perfect specimens obtained were such as had been dried 
in a heap of the sand. In any other way it would be impossible to 
kill them without breaking into small pieces, from the extremely 
fragile quality of the rays or arms. 
It is, probably, a very rare species, as we do not find it de- 
scribed by any author an opportunity has offered of consulting. 
We have never found it but in the place above mentioned, and 
there only a few have occurred.
