TESTACELLA IN STAFFORDSHIRE. 



By JOHN R. B. MASEFIELU. 



(Read before the Society, Sept. 13, 1911). 



Mr. Bryan, the Assistant-Curator at the Hanley Natural History 



Museum, who has probably studied the Staffordshire Testacella more 



than any other malacologist, has sent me the following notes, which 



may be of interest in connection with Mr. L. E. Adams's paper on 



the distribution of these slugs in the last number of the Journal : — 



"The only species of Testacella recorded as liaving occurred in 



Staffordshire is T, haliotidea. The species was first recorded as 



an addition to the Staffordshire mollusca in 1S97, when two 



specimens were found by Mr. Nicklin, who dug them up in his 



garden, near Trentham, from a depth of about twenty inches 



below the surface of the soil. One was an adult slug, and the 



other immature, and they were found about twelve yards apart. 



No further specimens were recorded until 29th July, 1905, when 



I received a half-grown specimen, found in a forcing-frame in a 



garden at Dresden near Longton. 



" On 2ist April, 1906, 1 obtained an adult specimen from the same 



garden, where a few days later I saw two young mutilated 



specimens. 



"About the middle of July, 1909, I turned up two more specimens 



in a garden at Shooter's Hills, near Longton, from underneath 



loose bricks and a log of wood. On 21st July in the same 



year, I obtained three more young slugs of this species ; and on 



iith May, 1910, two more adult specimens from underneath 



pieces of wood in the same locality. 



"All these specimens belonged without doubt to the species 



T. haliotidea, and I have not met with either T. niaiigei or 



T. scutuliiiii, although I cannot see why these latter species 



should not have been introduced as well as T. haliotidea. 



"From the recorded habitats I have given, I think with Mr. L. E. 



Adams that the evidence is conclusive that the species has 



been artificially introduced into Staffordshire."
