PROF. F. J. BELL ON ECHINODERMS 



[June 19, 



Echinoids, all of which had been collected at Aripo by M. Alois 

 Humbert. Of these four {Phyllacanthus annulifera, Temnopleurus 

 reynaudi, Clypeaster humilis, and Laganum depressum), G. humilis 

 has been found by Mr.Thnrston. 



Of the Echinoderms collected by Dr. John Anderson, F.R.S., in 

 the ]\lergni Archipelago, reports on the Ophiuroids by Prof. Martin 

 Duncan, F.R.S., and on the Holothurians by myself have alone 

 appeared as yet^ ; these, as well as the forthcoming reports by 

 Dr. H. Carpenter and Mr. Sladen, should be consulted by the • 

 student who desires to make himself acquainted with the Echino- 

 derm fauna of the Indian Ocean. 



I shall probably best serve the cause of brevity and clearness if I 

 follow the arrangement of the Andaman Report, and give first a list 

 of the species collected, and then some notes and descriptions of the 

 new species. With regard to some of the Temnopluroid forms and 

 a new Ophiuroid, apparently allied to Hemieuryale, I reserve an 

 account till I can deal with them in monographical detail. As 

 usual, there are a few Holothurians which cannot be at present 

 satisfactorily determined.
