I was at first inclined to consider tlie four specimens whicli I 

 include under this name as representatives o£ a new species. 

 Carpenter's species is, however, founded on two specimens of 

 much the same size, and smaller and younger examples such as I 

 have had before me might well have a smaller number of cirri 

 and a less marked development of the ridge on the more distal of 

 the arm-joints. Antedon jiexilis, A. patula, and A. rohusta were 

 all taken at the same station by the ' Challenger ' ; and it is very 

 likely that an increase in our series may show that there are not 

 so many well-marked species as has been supposed.

The specimens about to be described form part of a collection 

 from Borneo, forwarded to the British Museum in June of this 

 year. The types of all the new species have been liberally 

 presented to the Museum by Mr. A. Everett, by whom they were 

 collected. A previous consignment also collected by Mr. Everett 

 in that island has been carefully worked out by Lieut.-Col. H. 

 H. Grodwin-Austen in the Proceedings of the Zoological Society, 

 1889, pp. 332-355, and 1891, pp. 22-47 They were all obtained
