[Helix fusca Mont. 



This species occurs abundantly in Yedmandale, a few 

 miles beyond the Riding boundary, and still nearer, "near 

 the Derwent at Castle Howard Railway Station" (W.D.R. 

 J. of C. vii., p. 131), but it has not yet been recorded for 

 the East Riding. " No Helix fusca,'" Howsham Woods

Helix itala Linn. 



This species has not been recorded for Derwentland, and 

 is rare in Holderness, where all its known stations are on 

 the drier glacial gravels. It is a characteristic shell of the 

 central division.
