Vol. V, p. 510 ; Wright, Challenger Reports Ixiv, p. 88. 

 Specimens collected by the Challenger at Port Jackson, 30 to 



35 fthms ; Twofold Bay, 150 fthras. 

 Specimens collected by H. M.S. Alert, now in British Museum, 



in Magellan Sti'aits, sandy bottom, 30 fthms, apparently 



belong to this species. 



(10) Epizoanthiis jycbTasiticus, see (8). 



(11) Clavularia aiistraliensis (sp. nov.) 

 Specimen growing on a sponge. 



Stolon, thin, membranous, plate-like, becoming divided at the 

 edges into narrow ribbons. 



Polypes crowded together in the central regions of the colony, 

 scattered and separated by considerable intervals at the 

 edge ; partially retracted. The average length is 3mm., 

 and the average breadth 15mm., but they vary very con- 

 siderably in size. 



Spicules numerous in the polypes, few and scattered in the 

 peripheral portions of the stolon ; -2 to •3mm. long ;. 

 spindles with very prominent wart-like projections. 



Colour, brownish-white. 



(12) Epizoanthiis parasiticus, see (8). 



(13) Mopsea clichoioma (I) 



A small fragment only of a Mopsea which apparently belongs 

 to this species. 



(14) Telesto smtthi. 



I can form no grounds for separating this specimen from 

 T. smithi. It should be noted that some authors use, 

 and with justice it appears to me, the stolon or root of 

 the Telestos as one character useful for classification. 

 None of the specimens submitted to me have this. 



(15) Gerardia (sp.) 



As a volume of the Challenger Reports, dealing with the large 

 and interesting collection of the Antipatharia obtained by the 

 expedition, is shortly expected, I have postponed the identification 

 of this valuable specimen. It does not appear to differ very 

 markedly, however, from G. lamarclci. 



(16) Sijmpodium verrilli (Percival Wright and Studer). Challenger 



Reports Ixiv, p. 271. 

 The specimen sent me is growing on a piece of Alga, and 



agrees fairly closely with the description of the species 



mentioned above. 

 ^\\e polypes are all completely retracted, a wart-like prominence^ 



marked by an eight-rayed star, indicating their position.
