EDITORIAL. 



We have pleasure in announcing that Mr W. Denison 

 Roebuck, Hon. Recorder of the Conchological Society, 

 proposes to publish in our pages a series of articles on the 

 various areas of Scotland in which it is desirable that further 

 molluscan investigation should be undertaken. The first of 

 these, dealing with Easterness, appeared in our last number, 

 and the succeeding papers will treat the subject on precisely 

 the same lines. In order to make the various lists more 

 complete, he is anxious to have the opportunity of examining 

 any material either existing in private collections or obtained 

 during the coming collecting season. We trust, therefore, 

 that such of our readers as have specimens in their possession 

 from any part of Scotland, or who have the opportunity of 

 collecting, will assist in this useful work. The area next to 

 be dealt with is East Ross, i.e. that portion of the county 

 which lies within the eastern watershed, and specimens from 

 this vice-county are desired zvithout delay. They should 

 be addressed direct to Mr Roebuck at 259 Hyde Park 

 Road, Leeds. 



The feeding habits of the Purple-tipped Sea-Urchin 

 form the subject of an interesting article by H. N. Milligan.^
