[CEYLON PEARL OYSTER FISHERIES 1905 SUPPLEMENTARY REPORTS, No. XXVIII.] 



APPENDIX TO THE REPORT 



ON THE 



ALCYONARIA 



COLLECTED BY 



Professor HERDMAN, at CEYLON, in 1902. 



BY 



Professor J. ARTHUR THOMSON, M.A., University of Aberdeen. 

 [With ONE PLATE and TWO TEXT-FIGURES.] 



A revision of the collection of Ceylonese Alcyonarians has enabled me to add to the 

 list given in Supplementary Report No. XX., by Mr. W. D. Henderson and myself.* 

 The additions are : 



Spangodes cervicornis, Wright and Studer. Caligorgia versluysi, n. sp. 



,, involute,, Kukenthal. Bebryce indica, n. sp. 



,, putteri, Kukenthal. Acampiogorgia gracilis, n. sp. 

 microspiculata, Putter. ,, rubra, n. sp. 



var. ceylonensis, now Muricella rubra, n. sp. 



Chironephlhya indica, n. sp. Virgularia elegans, Gray. 

 Suberogorgia kottikeri, Wright and Studer, var. ,, calycina, n. sp. 



ceylonensis, nov. ,, indica, n. sp. 



,, rubra, n. sp. Fusticularia herclmani, n. gen. et sp., Simpson. 



One of these [Caligorgia versluysi) is hardly an addition, since it replaces Primnoa 

 ellisii, von Koch (= Caligorgia ellisii, = C. verticillata). For this correction I have to 

 thank Dr. J. Versltjys, Amsterdam. The last on the list, Fusticularia herdmani, 

 represents an interesting new genus, which has been separately described by 

 Mr. J. J. Simpson, M.A. ('Annals and Magazine of Natural History,' June, 1905). 



* By an oversight the two species of Xenia (Part III., pp. 271, 273) were misplaced; they should come 

 first in the order Alcyonacea. On p. 289, the title of the family Muriceidse was omitted in front of 

 Acanthogorgia.
