2 GWYN JEFFREYS : ON MONTAGU's BRITISH SHELLS. 



It may be observed that Montagu (like all of us) made 

 mistakes, in his case as to the names of certain specimens, as well 

 as in being too credulous with respect to the communications of 

 Capt. Laskey and Mr. Bryer. 



The writing of Montagu will be represented by inverted 

 commas. The names are given in the same order as I adopted 

 in "British Conchology." 



LAND AND FRESHWA TER. 



" Helix rufescens, hispid." H. hispida, L. 



"Helix hispida." H. sericea, Miiller. 



" Helix fusca." One specimen is H. Cartusiana, Miiller, as is 



also the Scotch specimen mentioned by Montagu. 

 "Turbo muscorum." One specimen is Pupa marginata, Drap- 



arnaud; the others are P. umbilicata, Drap. 

 "Tur. Rolphii." Clausilia Rolphii, (Leach MS.) Gray. 

 "New from Scotland, Mr. Laskey." Clausilia parvula, a 



Continental species. 

 In a small turned box, full of Helix pulchella and other land 

 and freshwater shells (apparently the rejectamenta of a river 

 or stream), are specimens of Zonites crystallinus and Pisidiiim 

 fontinale, neither of which was noticed by Montagu. 



MARINE. 

 CONCHIFERA. 



"Pecten Isevis." P. maximus, L., young. 



"Pecten subauriculata" is represented by two specimens thus 

 named, but in separate boxes. The smaller specimen 

 agrees with Montagu's description and figure, and is a 

 quarter of an inch long. The larger specimen is marked 

 "Zetland, Mr. Fleming," this is Lima elliptica, Jeffreys, 

 and is half-an-inch long.
