HYDROZOA RITCHIE. 811 



The skeleton of a single dried colony is a little over one foot in 

 height. It originally consisted of three almost equally developed 

 liranches, of which two remain. The stem is 18 mm. in diameter 

 at the base. Tlie habit of the colony resembles that of some of 

 the Gorgonid Alcyonarians of the genus Juncella ; but the 

 growth is not so luxurious nor so sturdy as in the specimen 

 figured by Spencer (PI. 17, fig. 1), although the colony somewhat 

 exceeds his in height. The diameter of the aperture of a hydro- 

 phore was found to vary from 0-12 to 018 mm. 



Locality. — Off the coast of New South Wales. 



The species has hitherto been found only in Bass Strait, near 

 Port Phillip Heads, Victoria. 



Family EUDENDRID^. 

 EUDENDRIUM, sp. indet. 



Station 36. 



Poor specimens, without coenosarc, and consisting of short 

 stems from which a few branches with ringed bases arise, repre- 

 sent an indeterminable species of Eudendrium. It is probable 

 that the specimens belong to the species E^tdendrium pusillum, 

 which von Lendenfeld^ recorded from Port Jackson, in the same 

 neighbourhood in 1885, and which Miss Thornely has since 

 described from the Gulf of Manaar.* 



Locality. — Station 36, off Botany Bay, one mile from shore; 

 depth, 23 to 20 fathoms; bottom, sand tp rock; 11th March, 

 1898.
