In February 1903 there arrived at the Zoologiral Dcparlmcnl of 

 the Owens College, Manchester, a quantity of dried mud, contain- 

 ing Crustacea, which had been taken from a shallow poad in 

 the neigidjourhood of Port Elizabeth, Cape Colony, in 1897, by 

 Mr. Hodgson, and sent in the first instance to Dr. Allen, Marmc 

 Biological Laboratory, Plymouth. On being received at Manches- 

 ter, ou February 0, the mud was placed in a small aquarium, in 

 the hope of rearing some of the Crustacea (Phyllopoda), and kept 

 under observation by Mr. Wadsworlh, assistant m the labora- 

 tory, who noticed that in a few weeks a number of green shoots 

 had grown out of the mud. The plants were at first thought to 

 be Algae, but in the beginning of May they were found to be 

 fruiting, recognised as llepatics, and sent to the writer for inves- 

 tigation. The plant was at once seen to be a species of R>clla, 

 and on comparing with it the descriptions and figures of various 

 species which have been pvd.lished up to the present time by 

 dilTercnt authors (Bory et Montague, Trabut, Corbicrc, Lcitgeb, 

 Goebel, Porsild, Howe and Underwood), and referring to the 

 specimens issued by M. Ilusnot in the « neputic|e Galliie », it 

 would appear that this South African plant , wh. si evidently 

 coming nearest to It. hcUcophylla, is sufficiently distmct from 

 any species hitherto described to warrant the establishment of a 

 new species, which may be characterised as follows :

JUella capensis, sp. nov. 

 Dioecious ; plant erect, 10-30 mm. in height, usually branching
