line of former labra is visible when the aperture of the shell is 

 towards the eye, and it passes much more obliquely across the 

 spire than is represented in the figures referred to. Although 

 not extending in an uninterrupted line from the body-whorl to 

 the spire, still the old lips, even on the topmost normal volutions, 

 are visible under the lens, but at irregular intervals, as is also 

 the case in E. Martinii A. Adams. Mr. Marrat, however, is 

 quite right in regarding this species as distinct, and I only regret 

 that he has imposed a name upon it which applies nearly to 

 every species in the genus, and indeed I feel almost tempted to 

 re-name it (after my friend), a practice, hovv^ever, not to be com- 

 mended except in very exceptional instances. 



Obituary.— John Gwyn Jeffreys, LL.D., F.R.S., &c. 



The chief authority on the MoUusca of European and 

 Arctic Seas is no more. Dr. Gwyn Jeffreys died after only a 

 few hours' illness on Saturday, January 24th. This veteran 

 conchologist, who was hale, hearty, and in full vigour of mind 

 to the last, had just entered his 77th year. For nearly sixty- 

 five years he had been engaged in the study of conchology, and 

 increasing years had not diminished but rather heightened his 

 ardour as a collector and a student. Dr. Gwyn Jeffreys was 

 essentially a conchologist. He did not deeply study such groups 

 as the Limacidse, the Nudibranchiata, or the Cephalopoda ; but 

 as an authority on the shells of the North Atlantic he stood 

 facile princeps. The knowledge he possessed he was always 

 ready to use for the benefit of others. It was his delight to 

 lend a helping hand to tyros and assist young conchologists in 

 the determination of their specimens, and no small portion of 

 his time was occupied in this kind of work. Many of our 

 subscribers, as they read these lines, will realise how kind and 

 sympathising a friend they have lost in him who had so often 

 and so good naturedly helped them in their difficulties. For 

 fifty-six years Gwyn Jeffreys had been writing on the mollusca,
