quite normal, and within the lip, the ledge or ridge which suj)- 

 ported the operculum (unfortunately not preserved) is partly 

 developed. 



The specimen was found in the River Cam, not far from 

 Cambridge, by the Rev. E. vS. Dewick, M.A., F.G.S., who has 

 kindly presented it to the British Museum. 



Helix lapicida (L) var. albina (Menke) in Derbyshire. 



— I have in my collection two specimens of the above variety, 

 differing only in the uniform greenish-white colour from the 

 typical form. Both were given me some few years ago by the 

 late Mr. Thomas Glover, of Manchester, who found a colony of 

 them, all precisely similar in appearance, on the limestone near 

 Matlock on August i6th, 'iSyp. Though not unfrequent in 

 some parts of the continent of Europe, this variety seems to be 

 hardly known in England. I should much like to know of 

 other records. At the time of the publication of Jeffreys' 

 British Conchology (1865) it was evidently quite unknown in 

 this country. — J. Cosmo Melvill. 



Helix lapicida monst. scalaris Charp. in Derbyshire. 



— This monstrosity, which has a decidedly elevated spire, whorls 

 much separated, and sutures deep, was found by Mr. J. Allen 

 Howe while collecting during 1887 at Matlock Bath, Derby- 

 shire. — [Rev.] H. Milnes. 



Otina Otis var. alba at Newquay. — Although Newquay 

 is perhaps the most unproductive coast, as regards marine shells, 

 which I have ever visited, specimens of Otina otis Turt. var. 

 alba occur in considerable numbers and of large size. They 

 occur in caves, associated with Alexia bidentata Mont. I have 

 taken the type at Tintagel and at the Lizard, as well as in the 

 Scilly Islands. — [Rev.] A. H. Cooke.
