PROCEEDINGS OF THE CONCHOLOGTCAL SOCIETY. 55 



Mr. W. D. Roebuck exhibited a number of living slugs, 

 including Arion hortensis, Amalia gagates, A. marginatus, Limax 

 flavus, L. agrestis and L. fuaxtmus, sent by Mr. C. Ashford 

 from Christchurch. Several of the specimens were of anomalous 

 colouration, particularly the Arion and the Limax 7naximus ; 

 and Mr. Roebuck pointed out that a great deal of work 

 required to be done before it could be said that the latter 

 species was well known, and particularly directed the attention 

 of members to the fact that while Moquin-Tandon laid much 

 stress on the importance of the bi-centrical arrangement of the 

 striae on the shield of L. maximus, considering it peculiar to 

 and characteristic of the species, the character could not be 

 detected at all in Mr. Ashford's English examples; thus raising 

 doubts as to whether the character possesses the value attached 

 to it by Moquin-Tandon. 



On behalf of Mr. Ingleby of Eavestone, near Ripon, a 

 number of shells were shown which had been collected in that 

 neighbourhood.
