Succinea putris v. Ferussina Moq-Tand. — The two speci- 

 mens of ^. putris seem referable to this variety. They 

 agree exactly with the figures given by Dr. Baudon in his 

 Monograph of Succinea, and accord well with the descrip- 

 tion. The dimensions are ii ^ mill, x /i^/o, mill. ; aper- 

 ture 6^ mill. X 3!/^ mill. 



Zonites cellarius Miill. — Two examples of this species were 

 sent. One was an extra large specimen, rather more 

 elevated than usual, and without trace of the usual whitish 

 opacity around the umbilicus. The size is 13^ mill, in 

 diam. with an alt. of 6^ mill. Dr. Jeffreys gives the 

 average dimensions as 5 mill, high and 12)^ mill, broad. 



Zonites alliarius (Miller). — The two specimens of this 

 species are of ordinary appearance, but with the spire 

 more elevated than given by Dr. Jeffreys. The dimensions 

 are : alt. 3^ mill., diam. 6^^^ mill. Dr. Jeffreys gives the 

 diam. as 6^ mill, and alt. 2j^ mill. 



Zonites nitidulus (Drap.). — Only one specimen of this 

 species was enclosed in the parcel. It is a trifle more de- 

 pressed than usual, having an alt. of 3^ mill, and a breadth 

 of Zy^ mill. The dimensions as given by Dr. Jeffreys are : 

 alt. 35^ mill., diameter a trifle over 8 mill. 



H. aspersa var. tenuior Shuttl. — ^A very interesting speci- 

 men of this variety was sent by Mr. Tomlin. It is very 

 thin and translucent and faintly banded with five trans- 

 parent bands, and is 21 mill, in diam., with an alt. of 

 i8>^ mill. 



Helix nemoralis L. — The six specimens of this species were 

 from Sark : half of them were of a somewhat depressed 

 form, and one more conical than the others. I give full 

 particulars as follows : —
