133 Mr. Jeffreys 0)i British Mollusca. 



Gasteropoda Pulmonifera. 



Helix aperta, iv. 43. Dr. Lukis thinks the specimen recordetl as 

 having been found in Guernsey by the late Professor Forbes was 

 accidentally imported ; and he adds that he has searched for the 

 species in vain. It is rather a common article of food in the south of 

 France and in Italy, and makes a dainty dish for snail-eaters. 



H. aspersa, iv. 44 1 . Mr. Barlee states, in answer to my inquiry 

 as to the existence of this species in the Shetlands, that he has not 

 been able to find it there. This common pest of our gardens does 

 not appear to be known in the north of Europe or in Germany. 



H. Pisana, iv. 5G1. On the western and southern shores of Jer- 

 sey (Br. Lukis) . 



H. ericetorum, iv. Gl. Dr. Lukis says this species has been taken 

 in Jersey, but is not now to be found there. 



H. globularis, Jeff'r. Linn. Trans, vol. xvi. p. .507. H.sericea, 

 B.M. iv. 71 (not of Draparnaud). Guernsey {Dr. Lukis). 



11. umbilicata, iv. 81. I found a specimen in trawled stuff from 

 Plymouth, which had been taken at a distance of several miles from 

 the shore. 



Pupa alpestris. Vertigo alpestris, Alder, Trans. Nat. Hist. Soc. 

 North, vol. ii. p. 340. Pupa Shuttleioorthiana, Charpentier in 

 Zeitschr. fiir Malak. for 1847, p. 148. P. pygmcea, var., B.M. iv. 

 106. Mr. Norman informs me that this species has been lately 

 taken, rather abundantly, by Miss Sarah Bolton in the neighbourhood 

 of Ambleside, on slate ; and he adds that the recent notices of its 

 rediscovery in the south of England and the neighbourhood of Dublin 

 (as respectively recorded in the ' Zoologist' for 18.50, vol. viii. p. 2743, 

 and the Nat. Hist. Rev. vol. i. p. 94) are erroneous, — Mr. Bridgman's 

 specimens from Norwich (judging from one which is in the British 

 Museum, labelled " Vertigo a/pestris") belonging to P. j)ggmcea 

 (which I can confirm), and an example of the Dublin shell sent to 

 Mr. Norman by INIr. Hogan as "Pupa alpestris," being quite a dif- 

 ferent species. I found specimens of P. alpestris at Zcrmatt and in 

 the valley of the Dranse, in 1855, and they were named by the late 

 M. Charpentier "Pupa Shuttleworthiana." Mr. Alder's name has, 

 however, the precedence of publication. Specimens which I have 

 received from Mr. Norman agree with those I found in Switzerland, 

 as well as with the description of i\Ir. Alder, who has recognized 

 them as his species. It is unquestionably distinct from P. pxjgmcea 

 or any of its varieties. 



Planorbis lacustris, iv. 1G2. Guernsey {Br. Lukis). 



Limneus acutus, Jefr. Linn. Trans, xvi. 373. L. auricular ins, var., 

 B. M. iv. 1 70. Neighbourhood of Oban ( Capt. Bedford) ; Bloonifield, 

 Kent. Although all the species of Limneus are especially subject to 

 variation of form, I much doubt if this is not distinct from L. aiiri- 

 cularius. It is certainly not an " immature \»x\Qty" of the last- 

 named sj)ecies, as stated by Forbes and Haniey, for I have found 

 specimens of all ages agreeing in a common character. 



L. glaber, iv. l/S. Guernsey {Dr.Lv.kis).
