Gends 'Rr&.bdopleura, Alliuan. (pd^So'i, rod ; 

 irXevpa, side.) 



Generic character identical with that of the family. 



1 . R. NoEMANi^ Allman. 

 Hab.: Shetland {A.M.N.). 



For a description of this species^ and of the curious 

 structure of the members of this family, the reader is 

 referred to the Q. J. M. S., January, 1869, where is an 

 article by Prof. Allman, who has made this species a 

 special object of study. For the purposes of this 

 book it is sufficient to state that Bhahdophura is re- 

 markable from the shape of the lophophore, and the 

 disposition of the tentacles. The former is prolonged 

 into two projecting arms or plumes, upon each of 

 which is borne a double row of tentacles. There are 

 other peculiarities of structure which are dealt with 

 in the article referred to. 



2. R COMPACTA. 



Found on the coast of Antrim in deep water by Mr. 

 Hyndman. 



Although its exact position is not yet fully made 

 out, it is proper to mention the fresh-water Medusa, 

 Lirmiocodium Sowerhii, found in the Victoria Regia 

 tank in the Royal Botanic Gardens, Regent^s Park, 

 in June, 1880, by Mr. Sowerby. The Medusa was 

 describedby Prof. Allman ("Nature," xxi. 178) under 

 the name L. Victoria, and by Prof. E. Lankester 

 (Q. J. M. S., XX. 351) under the name Craspedocustes 

 Sowerhii. Mr. G. J. Romanes {" Nature,'^ xxii. 191) 

 has also studied and described its structure; and 

 recently Mr. A. G. Bourne (Proc. Roy. Soc. xxxviii. 9) 

 has described what he believes to be its hydroid phase.
