TESTACELLA MAUGEL IN JERSEY. 

 By martin M. BULL, F.R.C.P.L. 



In April, 1878, 1 found a Testacella crawling on a path at the 

 foot of a low walk surmounted by a hawthorn hedge. The local 

 conchologists had not met with it ; but on enquiry I learned that 

 it had for some years been met with occasionally, about four 

 inches under the surface, in a dry bank about half a mile from 

 my locality. A specimen was brought me from thence shortly 

 afterwards. 



Keeping my eye on my own locality, I met with a second 

 specimen in November. M. Duprey, fils, to whom I gave it, 

 thought from the size of the shell that it might be Testacella 

 Maugei. 



I saw a third last month, crawling on the same path, at 2 p.m., 

 the others having been found at 9 a.m. I took it indoors, when 

 it presently emitted a mass of frothy mucus like soapsuds, 

 equalling about one-tenth of the bulk of its body, from under the 

 anterior margin of its shell. This led me to suppose that the 

 opening into the pulmonary sac must be in that situation, as I 

 did not see by what other mechanism such a mass of air-bubbles 

 could be produced. Being myself unacquainted with the anatomy 

 of mollusca, I communicated with the author of ' British Concho- 

 logy,' and sent the slug alive to him. Mr. Jeffreys informs me 

 that—" it is unquestionably Testacella Maugei" and that I am 

 " quite right as to the position of the respiratory sac."
