Achatina acicula in Northamptonshire. — The first 

 record of this interesting mollusk being found in this county is 

 given by the Rev. M. J. Berkeley, in the ' EngHsh Mechanic,' 

 Oct. 20th, 1876; this article on Northamptonshire as a field of 

 study for Naturalists, was reprinted in the Northamptonshire 

 Nat. Hist. Soc. Journal, vol. ii, pp. 347 to 351, and contains the 

 following paragraph referring to the above : — ' The delicate 

 Achatina acicula which is so seldom found alive, though not 

 uncommon in fresh water deposits, has occurred to me at Sib- 

 bertoft in full vigour.' In the list of Land and Freshwater 

 Mollusca collected at Peterborough by A. W. Nicholls ; ' Journ. 

 of Conch.', iv., p. 185, April, 1884, this species is recorded as being 

 rare in the gravels of the River Lane. In a letter to me dated 

 Oct., 1885, T. Beesley, F.C.S. of Banbury, writes as follows : — 

 ' This \_AcJiatina acicula'] I found some years ago very abun- 

 dantly in roots of grass, near a stonepit close to the town ; but 

 this was in Oxfordshire. If searched for, you will be sure to 

 find it. The pit was marlstone.' On Aug. 14, of this year, 

 while turning over some stones of the Middle Lias which had 

 been excavated for the new railway between Weedon and 

 Daventry, in a gravel walk, close to the latter town, I found a 

 single dead specimen of this species ; although careful search 

 was made, no further specimens could be found. — Walter D.
