previously been recorded for East Kent. Through inadvertency, I caused it to 

 be recorded for West Kent (see '• Conchologist," 1891, vol. i., p. 32). The 

 sentence should read " Helix aculeata in East Kent." — E. W. SWANTON. 



Note on the Land and Freshwater Molluscs of Suffolk. 



In the catalogue of the land and freshwater shells of Suffolk, by the Rev. 

 Carleton Greene,* the following species, which the writer recently collected in 

 that county, are not recorded. 



Amalia gagates, Drap., and Vitrea drapamaudi ', Beck, St. Margaret's, 

 Ipswich ; Palndestrina ulvce, Pen., Woolver Stone Park, Ipswich. Several other 

 species were turned up in the neighbourhood of Ipswich, for which that locality is 

 not given in the list, including Limax agrestis, L. ; Amalia marginata, Drap. ; 

 Vitrea glabra, Stud.; V. nitidula, Drap.; V. pura, Aid. ; V. fulva, Mull. ; 

 Arion hortensis, Fer. ; Helix pygnnca, Drap.; H. concinna, Jeff.; H. aspersa, 

 Mull. ; Cock, lubrica, Mull. ; Pupa umbilicaia, Drap. ; Vertigo pygmcea, Drap. ; 

 Ancylus lacustris, L. ; Planorbis vortex, L.; P. contort us, L. ; Physa fontinalis, 

 L. ; and Spharium lacustre, Mull. 



It were well, perhaps, to take the present opportunity of pointing out that in 

 the list above mentioned, and many others, notably one in the "Irish Naturalist" 

 which appeared recently, the compilers take no pains to arrange their genera in 

 an order based on the result of modern investigation, such as would be found in 

 a standard work on the Mollusca. For instance, the affinities of Arion with 

 Helix must be fairly well known. Why, then, place it between Vitrea and 

 Testacella, or separate it from Helix by these genera, with Limax, Vitrina, and 

 Succineal — Wilfred Mark Webb, F. L.S., Demonstrator in Biology, Essex 

 County Council. 



Testacella scutulum, Sby. 



It may be interesting to note that while making some recent investigations on 

 the anatomy of this species, which, in reality, is distinct from T. haliotidea, the 

 writer came across an individual from Buckhurst Hill, Essex, in which the right 

 upper tentacle was completely absent, the lower one of the same side being slightly 

 enlarged. The male portions of the reproductive system were also much reduced, 

 the tubes of the penis being mere threads. — Wilfred Mark Webb. 



Limnaea stagnalis monst. scalariformis. 



The pond on Chislehurst Common where the variety elegantula is found has 

 been almost dried up, and my brothers have succeeded in finding three more 

 scalariform specimens, one of which is considerably more so than the one figured 

 in " Science Gossip." Altogether, five scalariform shells have been found in this 

 little pond, which is never more than 35 ft. across, and is now in danger of being 

 altogether dried up. The animal of the var. elegantula has much more of the 

 yellow tint than the type, the sides of the foot being quite orange in some 

 specimens, the colour shading off into the darker colour of the rest of the body. 

 The tentacles are also yellowish. I have obtained a specimen of Pisidium 

 fontina/e var. cinerea in the same pond, as well as a number of Spluerium lacustre. 

 [I found this note among my papers ; it was written many years ago. The pond 

 in question is by the side of a road that runs across Chislehurst Common from 

 Prickend. It would be interesting if some conchologist would visit the spot now, 

 and see whether the var. elegantula is still there.] — T. D. A. Cockf.rell, F.Z.S.,

On the Occurrence of Cyclostrema millepunctatum, Friele, off the 

 Isle of Man. 



The systematic dredging operations which have been carried on by the 

 Liverpool Marine Biology Committee, under the direction of Professor Herdman, 

 have added very greatly to our knowledge of the fauna of the district. Even in 

 Conchology, well worked as the Irish Sea might be supposed to have been, 

 additional records are constantly turning up, almost every excursion bringing to 

 light some form not previously noted in the lists.
