214 JOURNAL OF CONCHOLOGY, VOL. I3, NO. 7, JULY, I9II. 



As an example of the un.satisfactory nature of ' garden records,' 

 when a comital area has been coloured red on the strength of one, I 

 will instance Milax gagates : — 



^"Northampton. — Mr. Beeby Thompson's garden, Northampton, 

 June, 1896 (L. E. Adams, Journ. Northants. Soc, 1896, p. 60)." 



This refers to a small colony which I once found under a plant m 

 a town garden. Though the entire county has been worked very 

 thoroughly by many conchologists, no other specimens have yet been 

 found. I have never had any doubt as to their artificial introduction. 



'■^"Stafford. — Grounds of Grammar School, Stafford, June, 1886 ! 

 L. E. Adams." 



This refers to two or three individuals that I found in the field 

 close to a low wall separating it from a large vegetable garden. This 

 county has also been very thoroughly worked, but no other captures 

 have been made. 



^"Cheshire. — Var. rai'a, nursery gardens, Sale, Feb., 1895 ! and 

 Ashton-on-Mersey, Oct., 1892, C. Oldham." 



Mr. Oldham informs me that he regards these slugs as undoubtedly 

 introduced. 



In the Appendix in the same volume of the " Monograph,'' p. 282, 

 there is the following record : — 



■"'Surrey. — Betchworth, Nov., 1906 ! Lionel E. Adams." 



This, of course, was received too late to be of service for the map 

 of distribution, which is, perhaps, just as well, as it refers to a colony 

 in an old kitchen garden — the only locality for the species known in 

 the county. 



No less than eleven out of the forty-nine comital areas are affected 

 by 'garden records' alone, and perhaps some of those not specified 

 as such may be so. It may be noticed that all the inland comital 

 areas depend upon these records alone, and, as I have said, I have 

 no doubt as to the artificial introduction of the species into Stafford 

 and Northants, and have every reason to conclude the same with 

 regard to Warwick and Middlesex. 



It is a species that is comparatively easy to acclimatise, and 1 know 

 of no geological reason why it should not occur naturally inland in 

 Britain, as it does on the continent, but the fact of its doing so is 

 not convincingly proved by the single 'garden records.'
