BIBLIOGRAPHY. 



Annals and Mag. of Nat. Hist.— Space does not permit us to detail 

 the arguments of Canon Norman in favour of retaining the generic 

 name Cydosloiiia. We strongly recommend all interested in the 

 subject to carefully read through his paper. 



A most interesting account of the nineteen species of molluscs which 

 have been placed in the genus Pytiiina is given by Mr. Edgar A. 

 Smith, who considers only one of the nineteen has any claim to be 

 termed /'y//ii/ia, viz., P. dcshaycsiaua Hinds. Of the remainder, 

 four he would place amongst the Mylifta, three in A'rHia, seven in 

 Tclliiiiya, three in Montacuta, and one in Lepion. 



Respecting the genus Mysclla, "which was created by Angas for 

 a small Australian bivalve," and described in the Proc. Zool. Soc. , 

 1877, p. 176, Mr. Smith points out inaccuracies in the original 

 description, and after a careful study of the types M. anoiiiala and 

 M. donacifoniiis he fails to see any reason for sejiarating them from 

 the genus Tellimya. 



My/e/ta aiiricidata is a new species described from three valves from 

 Tasmania. 



Messrs. Melvill and Ponsonby describe eight new land molluscs and one 

 freshwater from South Africa, viz. : six He/iiida-, one Feiiii^o, one 

 Cydostiviia, and one Pisidiiiiu. 



A List of the Land and Freshwater Molluscs of Barbados, enumerating 

 thirty-one species, is contributed by Messrs. Smith and Feilden. 



British Naturalist.— Mr. (lain describes the method he has adopted 

 for keeping molluscs in confinement, and gives a number of 

 interesting notes about various species. 



Naturalist. — Mr. Nelson contributes an interesting report of the 

 Yorkshire Naturalists' Union Excursion to Grassington, giving a total 

 list of 33 species, of which three were slugs, three freshwater, and 

 the remainder land. Vertigo edentnla and Hyalina piira were added 

 to the present known species of the district. 



Science Gossip. — The career of Hydrobia Jeiikiiisi has so far beeii 

 one of controversy and discussion. This new addition to the British 

 List was named by Mr. Edgar A. Smith in 1889, and described in the 

 "Journal of Conchology," Oct. 1889, p. 142. Mr. J. T. Marshall, 

 whose opinion is always worthy of deep consideration, considers it 

 only as a variety oi H. vciitrosa, viz., var. ovata. Mr. W. H. Smith, 

 writing in the " Essex Naturalist " and " Science Gossip," says : "It 

 is due to the energy of Mr. W. Allen that this species became known 

 to Mr. Crouch ... I think Hydrobia alleni would be a more 

 commendable name than Hydrobia Jeiikiiisi." Mr. Crouch and 

 Mr. Jenkins both reply, which can leave no doubt that they were the 

 active workers in establishing the new form. The naming of shells 

 after individuals is a practice to be strongly deprecated, and we must 

 confess we were surprised that so eminent an authority as Mr. E. A. 

 .Smith should countenance such a practice.
