 Ann. Nat. Hist. ser. 4, vol. xvi. pp. 90, 91 ; 2 woodcuts. 



It is proposed to separate the species hitherto included in the genus 

 into 2 groups — Platycrinus being retained for those species having the 

 mouth (?) at the end of a proboscis, while the species that have no pro- 

 boscis, and in which the mouth (?) is placed intermdially, are to be in- 

 cluded in a new genus, Medusacrinus. E. T. N.
