CEYLON PEARL OYSTER REPORT. 



Calliactis sp. Pearl banks, Gulf of Manaar. 



Chond ractinia digitata (Muller). Station XX., 11 to 13 fathoms, Trincomalee. 



Actinauge sp. (? n. sp.). West of Periya Paar. 



Another form, not identified, from Gulf of Manaar, shallow water. 



Several of the unidentified species in the above list are in all probability new to 

 science. Out of these 14 species 11 are new records to Ceylon, those previously 

 known being Zoanthus shackletoni, Pcdythoa tuberculosa and Sphenopus marsupialis. 



The only specimens in the Ceylon Collection that now remain unidentified and 

 unexamined, so far as I am aware, are about half a dozen Enteropneusta, belonging 

 apparently to three species. W. A. H. 



Our deck laboratory on the " Rangasami-Poravi."
