CURRENT LITERATURE. 37 



Helix vendryesi and Veronicella jamaicensis. (Tourn. Inst. Jamaica, 

 p. 55, 1S92.) 

 Mr. T. D. A. Cockerell describes the above two species, the former from 

 Montego Bay (W.I.), and the latter from Kingstown. This slug has already been 

 figured and described by Semper, and referred as doubtful to V. kraiissii, Fer. 

 [We much regret to find Mr. Cockerell has here departed from a rule he has 

 hitherto laid down and adhered to very stringently, viz., that of naming species 

 &c, after individuals and places.] 



New Australian Mollusca. (Trans. Roy. Soc. S. Aust.,vol. xiv, p. 257 and 265.) 

 Prof. Tate gives a second supplement to the list of Lamellibranch and 

 Palliobranch Mollusca of S. Australia. The new recent species belong to the 

 genera Siphonalia, Latirofusus, Diala, Leiopyrga, Semele, Tellina, Lucinopsis, 

 Crassatelta, Pectunculus and Leda. 



Some New Land Shells. (Brit. Nat., p. 125, 1S92.) 



Mr. C. F. Ancey describes the following new species : — Ennea consobrina, 

 from Cape Colony ; Helix melvilliana, from Ovampoland ; Nenia orbignyi 

 (allied to CI. crossei, Hidalgo), from Bolivia ; and Cyclostoma burtoni (allied to 

 C. anceps, Von Marten), found in the vicinity of L. Tanganyika. 



[Presuming that these shells were made and occupied by some animal, a 

 reference to the same would have been useful. In the absence of any description 

 of the paints of difference in the anatomy, we fear the latter two can hardly rank 

 as species until further and more completely described.] 



Pecton crouchi and Mitra fultoni. (Ann. and Mag. of N. H., pp. 255-6, 

 1892.) 

 Mr. Edgar A. Smith describes and figures the above forms, the former from 

 the Mauritius and the latter from Lower California. 



Unio oscari. (Nautilus, p. 124, 1S92.) 



Mr. B. H. Wright here describes a form allied to U- aheneus, Lea, from which 

 it differs, however, in having a much smoother epidermis, a deeper shell cavity, 

 and shorter and wider lateral teeth. Habitat: a creek from L. Osceola, Florida. 



New Unio (U. corbeti) from Ceylon. (Bull. Soc. Zool. France, T. xvii., 

 p. 68. ) — Emile Deschamps. 



VARIATION. 



Notes on Varieties. (Brit. Nat., pp. 70, 74, 105, and 127, 1892). 



Messrs. W. A. Gain and T. D. A. Cockerell contribute further notes and 

 observations upon this subject, which are interesting and full of suggestive points, 

 worthy of further attention. 



Variation of the Genus Arion. (Ann. and Mag. N.H., p. 307, 1892). 



Mr. W. E. Collinge, who is at present devoting some attention to the Arionidce, 

 here records some interesting forms of A. empiricorum, grouped as sub-varieties 

 of var. bocagei, Simroth. Speaking of the red forms of this species, Mr. Collinge 

 is of opinion that v. brunneus, Roebuck, would be better grouped as a sub-var. of 

 v. rufits, L. The v. subi-eticitlatits, Ckll., he also suggests might be similarly 

 grouped under v. reticulatus, Roebuck. The v.fallax, Ckll., of A. hortensis, Fer., 

 he views as a form of v. subfusm, C. Pfr., and questions the validity of v. albipcs, 

 Ckll. 



DISTRIBUTION. 



Mollusca of Lord Howe's Island. (Journ. de Conchl., Oct. 1891.) 



Dr. P. Fischer has an interesting article on the mollusca of Lord Howe's 

 Island (between New South Wales and New Zealand), compiled from the 

 publications of Etheridge and Hedley. The Land Mollusca are 21 (possibly 24)
