ffliizostomean Acaleph ( Cassiopeia ), found in the trawl

Further, several species of Rhizostoma occurring in our 
northern seas have a brown colouring matter which is pro¬ 
bably polyperythrin, but for the examination of which op¬ 
portunity has not presented itself to me. 
In the deep sea actinia obtained off Japan, the outer sur¬ 
face of the animal was of a pure white, and the colouring 
matter was found in the body cavity only intensely tinging 
the surfaces of the mesenteries and viscera. In the discosoma 
the colouring matter occurred in bands or streaks on the 
disc only. In the Rhizoslomean, which was unfortunately 
too much mutilated for identification, the whole of the sur¬ 
face of the umbrella was thickly covered with the pigment. 
A second similar acaleph was obtained in the South Atlantic 
likewise coloured with polyperythrin, but was like the other 
specimens very much torn. 
Polyperythrin has not been met with in any red coloured 
compound corals nor in any red Actiniada; living in shallow 
water, although many such occurring in various parts of the 
world have been examined, including the red and pink Hy- 
drocorallinac (Stylasteridae). Probably, in the numerous me¬ 
dusa; which have a red brown pigment, the pigment is polype¬ 
rythrin. I lately saw numerous Rhizostomeans cast up on the 
Norwegian coast thus coloured, but had not then a spectro¬ 
scope available. 
Jdamsia. —An Adamsia obtained off the Philippines in
