dividual differences, and unless we are prepared to accept an 

 excessive increase in the already large number of named 

 varieties we cannot avoid, in my opinion, placing together forms 

 differing so slightly as var. ovalifonnis and var. vulgaris. But as 

 the range of variation allowable in either species or varieties is, 

 after all, to some extent a question of individual opinion, the 

 preceding description and figures will enable those interested in 

 the subject to form their own judgment and render further dis- 

 cussion in the Journal unnecessary. 



Obituary.— Mr. Clifford Burkill. 



We regret to announce the death of Mr. Clifford Burkill, of 

 Scarborough, which occurred rather suddenly at Guernsey, on 

 Sunday, the 22nd of February, whither he had gone on a six 

 months' dredging excursion. 



Though a young collector and a recent member of the 

 Society, he was most assiduous and energetic in the pursuit, his 

 thorough examination of the Scilly Islands, where he spent the 

 summers of 1888 and 1890, having pretty well exhausted the 

 marine fauna of that group, as will be seen from his additional 

 paper in the Journal for April, 1891. 



He was much liked by all fellow-workers who came in 

 contact with him, to whom he was ever ready to give help and 

 advice, and he was the centre of a little group of conchologists 

 who assembled at Scilly last summer, consisting of Mr. Alex. 

 Somerville, F.L.S., the Rev. Dale Roberts, of Birmingham, and 

 Mr. Ruthven Sykes, when that outlying part of our coasts may 

 be said to have been thoroughly explored, and where such a 

 strong party of conchologists are not likely to meet again soon. 



Had he lived there is no doubt he would have become a 

 worthy and able conchologist, judging from the work he had 

 done in the field during the last four or five years, and he will 

 be greatly missed by the many friends and correspondents who 

 had the pleasure of his acquaintance,
