150 DESCRIPTION OF THE COPPINIA OF AX AUSTRALIAN HYDROID, 



Family EUDENDRIDAE. 

 Genus eudendrium Ehrenberg. 



EUDENDRIUM LEXDEXFELDI nom. HOV. 



Eudendrium pusillum Lendenfeld, Proc. Linn. Soc. N.S.W., IX., 1885, p. 

 352 (name preoccupied; not E. pusillum Sars). Not Eudendrium pusillum 

 Thornely, Ceylon Pearl Oyster Fisheries, pt. 11, Suppl. Rep. VIII. — Hydroida, 

 1904, p. 110, pi. 1, fig. 5. 



As the name Eudendrium pusillum was used by Sars in 1857, I, therefore, 

 substitute Eudendrium lendenfeldi for this species which was originally described 

 by Lendenfeld from Port Jackson. 



A comparison of Lendenfeld's type slide with Miss Thornely's description 

 and figure of E. pusillum from Cheval Paar in the Gulf of Manaar convinces 

 me that she has described a totally distinct species. 



Family SERTULARIDAE. 



Genus sertularia Linnaeus. 



Sertularia balei nom. nov. 



Sertularia loculosa Bale, Cat. Austr. Hydroid Zooph., 1884, p. 91 (part), pi. IV., 



fig. 5, 6, pi. XIX., fig. 9. Id,, Warren, Ann. Natal Govt. Mus., 1, 3, 1908, p. 



306, pi. XLVIIL, fig. 37, text-fig. 8. Id., Bale, Proc. Roy. Soc. Vict., XXVI.. 



1913, p. 121, pi. XII., fig. 7, 8. 



Sertularia turbinata Billard, Ann. Sci. Nat. Zool., (9), XL, 1910, p. 19 (in part). 



? Sertularia turbinata Ritchie, Proc. Zool. Soc., 1910, p. 821. 



Not Sertularia loculosa Busk. 



Not Dynamena turbinata Lamourous. 



This species has been confused with Sertularia loculosa Busk, which Billard 

 (4) has shown to be identical with Dynamena turbinata Lamouroux. 



Bale (2) originally associated several forms under the name of Sertularia 

 loculosa, some of which differ considerably from the typical form. He has since 

 shown (3) that they represent more than one species, but while accepting the 

 original name Sertularia turbinata (Lamourous) for Busk's species, he has re- 

 tained the name Sertularia loculosa, in a restricted sense, for this common short- 

 celled form. This procedure being contrary to the rules of zoological nomen- 

 claFure, I propose the name Sertularia balei. for this species. 



Sertularia tryphera nom. nov. 



Sertularia geniculata Bale, Proc. Linn. Soc. N.S. Wales, (2), III., 1888, p. 768, 

 pi. XVII., fig. 6-11. (name preoccupied; not Sertularia geniculata Linnaeus). 



As the name Sertularia geniculata was used by Linnaeus, I, therefore, sub- 

 stitute Sertularia tryphera for this species which was originally described by 

 Bale from specimens in the Australian Museum collection from Port Jackson.
