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.
