specimen with examples of '■'■ H. ruhiginosa, Zieg.," in the collection 

 lately acquired by the Trustees of the British Museum from the 

 Rev. E.. Merle Norman. This species, as shown by A. Schmidt ^ (who 

 adopted Ziegler's manuscript name), is distinct from, though nearly 

 allied to, that usually known on the continent as H. sericea, Drap. 

 {H. sericea, Miill., which is proved to be the young of another species 

 predates this name, but we are not concerned with the correct name 

 of this latter species at present). This is not the Helix sericea, Drap., 

 of Jeffreys (Brit. Conch.), which should be known as Hygromia 

 gramdata, Alder. Hygromia ruhiginosa has hitherto been unrecorded

from this country, either fossil or recent. Tryon is undoubtedly in 

 error in placing it as a variety of H. granulata, Alder.- It has been 

 recorded living from Scandinavia, N'orth Germany, Jutland, Saxony, 

 Bohemia, the JHartz, and the Carpathians.

The example from Bawdsey is stated by Mr. Wood to have been 

 found in loose and disturbed Crag, so it is possible that that one may 

 not be a true pliocene fossil ; but the examples from Bramerton are 

 undoubted as to their age. We cannot agree with Sandberger in 

 separating the Crag and the Forest Bed examples from the recent form. 



Judging from the figures and description, Vallonia sulpulchella, 

 Sanclb.,^ from the middle miocene, near Steinham in Wiirtemberg, is
