XXIV. — On the Genus Alicia (Cludactis), with an Anatomical 

 Description of A. costaj, Pane. By J. E. Duerde^,

 of Jamaica. 



[Plate IX.] 



While investigating, in conjunction with Prof. Had Jon, the 

 anatomy and relationships of a collection of sea-anemone3 

 from Port Phillip, Australia, it became necessary, in order to 

 determine the systematic position of one of them — Cystiaclis 

 tuberculosa J Quoy & Gaiin., — that a study of the genus Alicia 

 should be made. No specimen in this genus, so far as we 

 are aware, has ever been submitted to microscopic examina- 

 tion, a condition which is now absolutely necessary before 

 the relationship of any form of sea-anemone can be deter- 

 mined. 



The genus Alicia was founded by J. Y. Johnson (1861) 

 for a new form of sea-anemone — Alicia inirahilis — from 

 i\Iadeira. Andres (1884), disregarding Johnson's priority, 

 places this species under the genus CladactiSj founded by 

 JPanceri in 1868 for a Mediterranean Actiniarian, Cladactis 

 casta?. Verrill (1869), quite indcj)endi'ntly, founded a genus 

 of the same name tor a new Panaman species, Cladactis 

 grandis. Prof. Haddon and Miss Shackleton (1893) restore 

 Johnson's Alicia in place of Cladactis, and add a new species, 

 Alicia rhadina, which they regard as undoubtedly allied to 

 Actinia pretiosa, Dana, fron> Fiji. They therefore show the 

 genus Alicia to include the following: — A. mirabilis, Johns.
