324 NOTES ON THE ECHINODERMS 



Notes on the Echinoderms collected by Mr. Bourne in 

 Deep Water off the South-west of Ireland in H.M.S. 

 "Research."

Mr. Bourne lias been good enougli to submit to me most of tlie 

 interesting specimens of Echinoderms wliicli he obtained during his 

 short stay on board H.M.S. " Research.'^ Coming so soon after the 

 important collection made by the Rev. W. S. Green in neighbouring 

 waters and at greater depths, it will, I think, suffice for me to treat 

 this collection as an appendix to that, and to refer for a general dis- 

 cussion of such points as appeared worth noting to my i-eport in the 

 Annals and Magazine of Natural History for December last. 



The great interest of Mr. Bourne^s collection lies in the remark- 

 able way in which the depths of some of our more common shallow- 

 water species is increased, in some cases indeed to a remarkable 

 extent ; see the cases of Stichaster roseus, Asterias rubens, A. gla- 

 cialis, and Spatangus jpurpureus. 



The species which were observed on board ship, but which were 

 not preserved, are indicated by an astei'isk.
