576 NOTES ON THE DISTRIBUTION OP CERATELLA FUSCA, GRAY. 



The whole of the specimens are in a splendid state of preserva- 

 vation. A portion of the specimen obtained by Mr. Whitelegge 

 in May, has been mounted by him for microscopical examination. 



Dr. von Lendenfeld in his paper on the Australian Hydro- 

 medusae (loc. cit. p. 612), is very curt when he says that Dr. Gray's 

 description •' is worthless." If the description is worthless the 

 figure given by Gray is to the point in all that is required, for 

 though this naturalist generally gave a short description of nearly 

 everything he described, he always took care to give good figures. 



Mr. H. J. Carter, E.R S., in his valuable paper on the 

 Hydractiniidse (loc. cit., p. 10), calls attention to the excellent 

 illustrations given by Dr. Gray, and any scientist who has seen 

 them cannot but acquiesce. When Dr. E. P. Ramsay was in 

 London some two years ago, he obtained from the British Museum 

 some Hydroids, named by the authorities of that Institution, and 

 among them is a specimen of Dehitella atrorubens, Gray, Algoa 

 Bay, with a reference name Geratella fusca, Gray. This is 

 undoubtedly Dehitella atrorubens, Gray, the Australian Museum 

 never having received any specimen or specimens of Ceratella 

 fusca, Gray, from the British Museum. The specimen so named 

 is Dehitella atrorubens, Gray.
