Hydrozoa. 3 1 5 



DISCOMEDUS^. 



An Epliyra, at rather an advanced stage, was taken on 10th May, 

 1899. 



Umbrella about 25 mm. in diameter. About 12 tentacles on the 

 margin of the umbrella. Tentaculocysts present, but complete 

 number uncertain, as the margin is torn in places. 



The specimen looks like the Ephyra of a Chrysaora. It is rather 

 rotten and too damaged for a proper description. 



CYANEIDJE. 



Desmonema ? 



Four large specimens in the collection, which probably belong to 

 this genus. 



All the specimens are in very bad condition, and very rotten. 

 They were apparently stored in tins or an iron drum containing 

 formaline, and consequently were found covered with a heavy 

 deposit of iron rust which has deeply stained the jelly. They 

 are also badly compressed, and have the appearance of having been 

 placed under a weight. There are eight groups of tentacles inside 

 the margin of the umbrella, each group with two or more tentacles 

 in a single row. Probably eight sense organs present, but tlie full 

 number cannot be found. 



Taken on 20th and 27th December, 1899, and 17th January, 1900. 

 Near the surface. 



SIPHONOPHORA. 



CALYCONECTIDJE. 



Diphyidae. 



Several bottles containing nectocalyces only of a large Diphyid. 

 Taken during November, 1899, and January, 1900.
