THE JXHINODERMS OF GUERNSEY 



B Y M II . E . S H A R V . 



Although the rocky shores of Guernsey are the home of 

 innumerable Echinoderms there is no connected list published 

 that I am aware of, except the one given in Ansted's Channel 

 Islands. The following list is based on Forbes' " British 

 Starfishes," which is the standard work on this subject. It is 

 fairly complete except, perhaps, in the Brittle Stars, to which 

 two or three species may be added. These species are those 

 small ones closely resembling Aniphinra elegans^ which only 

 differ in the arrangement of the plates. It is probable also 

 that other species will be found among the Holothurians and 

 Sipunculida?. 



Thirty-eight species ai-e recorded in the following list. 

 Recent records alone haie been given, except where I have 

 been unable to obtain them. In these cases I have inserted 

 the species on Ansted's authority. For the benefit of 

 aquarium keepers I have added a few notes on Echinoderms 

 suitable and unsuitable for keeping alive in an aquarium. In 

 conclusion I should like to thank all those who have helped 

 me in procuring specimens and in noting localities, especially 

 Mr. F. S. AYright, of the Guille-Alles Library, and Mr. J. 

 Sinel, of Jersey, for notes on some of the rarer species. 



CRINOIDEiE. 



Comatula rosacea (Rosy Feather star; . Abundant in deep water (HornelF .

 in the proper season" (Hornell). Colour variable, generally red, but 

 sometimes yellow, old gold, or banded. 



OPHIURID^. 



Ophiura textUPata •'Common Sand star). On sand and mud bottoms from 

 littoral to deep water. Not uncommon. Colour chalky -white, the whole 

 animal looking as if it was carved in chalk.
