In the latter half of August I spent a few days in the neighbour- 

 hood of Topsham, with my friend, Mr. L. F^. Adams, and among 

 other shells we collected were the following, which are not in- 

 cluded in Mr. E. D. Marquand's List (' J.of C,' vol. vi, p. 136). 

 Arion ater. — We did not see a single typical afcr, but found 

 several specimens of the van hicolor in grass by the road- 

 side near Topsham. 

 A. subfuscus. — Two or three specimens in the same place as 



the last species. 

 A, minimus. — One at Exmouth. 

 A. hortensis. — Common at Topsham. 



Amalia gagates. — This species and the three following ones 

 were extremely plentiful in Mr. H. McMurdo's garden at 

 Topsham. The typical form o{ ga gates was not seen at all, 

 the majority of those collected being referable to the var. 

 rava, a few examples of the \d.r. plui/idea being noted. 

 A. sowerbyi. 

 Limax flavus. 



Agriolimax agrestis. — Common on the road-sides and hedge- 

 banks.

A. /nini/iiits. 

 Hyalinia nitida. — Three specimens under a log in a meadow- 

 near Topsham. 

 Helix rotundata, — A single specimen of the var. alba with 



the type at Topsham. 

 H. caperata var. fulva. — A few on a bank by the road-side 



at Topsham. 

 H. virgata var. lutescens. — Very plentiful on the road-side 

 between Exeter and Topsham ; also at Exmouth.
