432 Zoology 



170 species enumerated in the list of non- marine British molluca 

 prepared by B. B. Woodward, and published in 1904 by the 

 Conchological Society, my present list contains no fewer than 

 99, or about two-thirds. It is probable that further search might 

 add VITREA LUCID A (which I found this year in the grounds of 

 Fulham Palace), and HYGROMIA GRANULATA (which I got 

 last year at West Drayton). ANODONTA ANATINA should 

 also be found say in Danson Park lake. It should be noted that, 

 in his 170 species, B. B. Woodward includes at least 25 which are 

 either aliens (not undesirable) introduced, but hardly naturalised 

 nor commonly found, or are those no longer living in Britain but 

 occurring in the Post-Pliocene deposits other than the Forest Bed 

 series. This reduces the 170 to 145, and as three more are confined 

 to Ireland, we have already 99 out of 142 species as found in our 

 district, an abundance due to our being largely on the chalk, and 

 further, as regards nine species, to our having the brackish water 

 of an estuary in our bounds. I proceed now to enumerate and to 

 give, where necessary, localities and names of responsible observers. 

 As regards the latter, to save space : 



R.A.A. = R. A. ADKIN, F.E.S. J. and G. = A. J. JENKINS and 



Cl. = T. D. A. COCKERELL. L. O. GROCOCK. 



C. = J. E. COOPER, M.M.S. L. = B. T. LOWNE. 



H. CANON J. W. HORSLEY. S.K. = A. SANTEB KENNARD, F.G.S. 

 K. = H. WALLIS KEW, F.Z.S M.M.S. 



Several of these gentlemen have most kindly sent in M.S. lists 

 of species with observations, and Mr. Santer Kennard has also 

 read the proof-sheets. 



Testacella haliotidea, Drap. Fairly abundant in garden 

 Rectory Place, Woolwich, 1892 (H.) ; Shoreham Vicarage, 

 1897 (Ashington-Bullen) ; subterranean and nocturnal in 

 habits, therefore perhaps more widely distributed (H.) ; 

 Lewisham, common (R.A.A.) ; Beckenham, Keston (S.K.). 



Testacella scutulum, Sowerby. Garden at Perry Hill, Catford, 

 1903 (Mr. W. H. Griffin) ; many found in digging ; Beckenham, 

 Sydenham (S.K.). 



Limax maximus, Linne. Coney Hall Hill, W. Wickham, 1906 (K.) ; 

 probably elsewhere (H.) ; Orpington, 1904 (R.A.A.) ; Bromley, 

 common (S.K.); Beckenham, Eynsford (S.K.). 



Limax flavus, Linne. Catford, 1906 (L.) ; common on old walls at 

 Bromley (H.) ; Lewisham. fairly common in gardens, Eltham, 

 Grove Park (R.A.A.) ; Deptford (J. and G.) ; Chislehurst (CL). 



Limax arborum, Bouch. (marginatus,Muller.). Copse at Hayes, 1890 

 (K.) ; previously recorded by Rev. Leslie from an oak copse at 

 Erith, 1874 (H.) ; Beckenham (S.K.) ; Chislehurst (Cl.).
