1893. lu 1895 a number of specimens — adults and young — 

 were obtained by washing specimens of the common Starfish, 

 Asterias ruhens, in a bottle containing methylated spirit, and 

 afterwards examining the residue. These specimens were of 

 a brick-red colour on the back, but nearly white beneath. 

 Their normal habitat is apparently on this kind of starfish.
