Miss Sarah P. Monks of San Pedro, California, has stud- 

 ied this species with reference to its variation and autotomy. 

 She finds the rays varying from four to nine ; due mainly to 

 autotomy and irregular restoration of rays. 



The regeneration occurring is not only the usual regen- 

 eration of lost rays, but a ray may regenerate a new body. 

 Frequently comet rays occur, that is stars with one long ray 

 and a number of small rays extending from a minute disk. 

 Single ravs are found without any external sign of a disk. 



Color in life "mottled reddish brown and ash color, with 

 tips of rays, or new portion of the ravs a brighter and uniform 

 red" (Monks).
