of the Land and Fresh-water Shells of Suffolk. 169' 



67. Helix lutea. Trans. Linn. Soc. vol. yiii. p. 22^. 



A specimen was found some years since on the banks of 

 the River Gipping at Sproughton, by my venerable friend the 

 Rev. James Lambert, of Trinity College, and formerly Greek 

 Professor in the University of Cambridge. This circumstance,, 

 combined with my having taken abundance of them at Win- 

 thorpe, on the banks of the River Trent, Notts, f after a flood) at 

 least thirty miles above its junction with the salt water, proves 

 H. lutea to be a fresh-water shell. Those found therefore by 

 Montagu ad littora maris must have been carried down to the sea 

 by some fresh- water stream, and afterwards thrown on the shore. 

 I have never taken it in a living state. It probably inhabits the 

 depths of rivers. 



68. Helix pellucida. Fenn.Brit.ZooL vol.iv. no. 134. 



Inhabits the Parsonage garden at Offton, and the grove in 

 which H. Somershamiensis is found ; plentiful also at the roots of 

 grass in the marsh within the Sea-wall at Shotley. 



In abundance in moss and under pieces of wood in Little 

 Stour wood, my garden and lawn, Wrabness, Essex. 



This is the Vitrina pellucida of Draparnaud ; a very distinct 

 species, but bearing some resemblance to the young of H. nemo- 

 ralis and H. hortensis. 



This shell varies as to the colour of its suture ; in some it is 

 whitish and more wrinkled than in others ; in some it is brown ; 

 whilst in others the brown, in particular lights, appears to be 

 gilded. 



The green colour of the shell is also of various hues ; and 

 young specimens are whitish, and have only two, or scarcely two, 

 volutions ; so that I think it is manifest that Draparnaud has 

 multiplied one species into three.
