2 Mr. J. J. Quelch on some 



ledge of the gonosome of Streptocaulus, which throws consi- 

 derable light on corresponding parts in other genera ; while 

 many facts in the variability of the corbula in Afflaophenia, in 

 the development of the ramuli in Streptocaulus and Antennu- 

 larta, and in the occurrence of nematophores in forms {Zygo- 

 phylax) other than the Plumulariidge are clearly established. 



The specimens were obtained under circumstances of great 

 personal inconvenience by Mr. Bishop as the cable came in, 

 and were carefully dried, preserved, and brought to the 

 British Museum, since, as he expressed to me, he thought it 

 likely that any specimens from the deep sea might be of 

 interest to naturalists. Mr. Bishop has thus earned the 

 thanks of all zoophytologists for this contribution which he 

 has made to their science, and has at the same time set an 

 example to all those who, whatever may be their station in 

 life, have more or less favourable chances of adding to our 

 stock of knowledge. 



The specimens of Cryptolaria presented by Miss M'Lea 

 are especially interesting, since they show the nature of the 

 gonotheca. Of much interest also are the specimens of Disti- 

 chojpora granulosa and D. conferta.

Two small specimens were obtained, which I have doubt- 

 fully referred to this rare species, with which they agree in 

 their shrubby habit, in their regularly annulated branches, and 

 in the irregular network of small tubes which cover the surface 

 of the main stems. It seems to differ, however, in that its 

 ramules are often much elongated, while the whole hydro- 

 phyton seems to be thinner and much more delicate throughout.

Several specimens growing together on a portion of the 

 cable are referable to this species. The specimen on which 

 the species was founded evidently was quite a young one ; 

 for though the ultimate ramuli and the hydrothec^ are com-
