A. H. CLARK : THE CRINOIDS OF THE INDIAN OCEAN. 



103 



The colour in spirits is white. 



Locality. — Andaman Islands. — One specimen. 



Remarks.— Although the single specimen upon which this species is founded 

 is small, yet the overlapping of the distal ends of the brachials and the struc- 

 ture of the cirri seem to indicate that it is in reality a small species, and not the 

 young of a larger one. The small number of cirrus segments separates E. minor 

 from all the other species of the genus except E. variegatus, but in the last the}- 

 are all subequal and about as broad as long.
