38 SECOND SUPPLEMENT TO THE CRAG MOLLUSCA. 



MELAMPUS FUSIFORMIS, 8. Wood, var. ELONGATUS. 2nd Sup., Tab. Ill, fig. 15; Crag 



Moll., vol. i, p. 12, Tab. I, fig. 14 ; and 1st Sup., 

 p. 3, Tab. I, fig. 1. 



Locality. Red Crag, Waldringfield. 



The above specimen was obtained by Mr. Canham, and is perfect, except a slight 

 fracture in the back, which, however, is no injury to the shape of the shell. It is more 

 elongated than any form of the genus that I am acquainted with, but, unfortunately, the 

 artist has not represented this character sufficiently in the present figure, which can 

 scarcely be distinguished from the original fusiformis. 



BULIMUS LUBRICUS, Mutter. 2nd Sup., Tab. IV, fig. 10 ; 1st Sup., p. 187. 



HELIX LUBRICA, Mull. Hist. Verm., pt. xi, p. 104. 



ZUA LUBRICA, Forb. Sf Hani. Brit. Moll., vol. iv, p. 125, pi. cxxv, fig. 8. 



COCHLICOPA LUBRICA, Jeff. Brit. Conch., vol. i, p, 292, pi. xviii, fig. 2. 



Locality. Red Crag, Butley. 



The specimen figured is that referred to in my first ' Supplement ' as found by Mr. 

 Canham, in the Crag of Butley, and although it is not uncommon in the Freshwater 

 deposits of Stutton, Clacton, Grays, and Copford, it is the first and only one that I have 

 seen from the Crag ; I have therefore had it figured. This shell has received several 

 generic names, but the above having been previously used in my list of the Land 

 and Freshwater shells in my second volume of the * Crag Moll./ I have not thought it 

 necessary to alter it here. 



POSTSCRIPT. 



DURING the progress of the foregoing through the press Mr. Jas. Reeve, of the 

 Norwich Museum, was good enough to send me a quantity of small shells, which he had 

 extracted from the sand of the Bramerton Crag Pit. These consisted for the most part of 

 specimens of species already figured and described, but among them were two or three 

 which appear to me to be quite new to the Crag, if not, indeed, undescribed from any 

 formation. These specimens are all more or less worn and imperfect, a character which 

 is not usual with the specimens of species belonging to any horizon of the Crag in 

 Norfolk ; and I feel little doubt that they are not shells which lived in the Crag waters,
