Light, N. Shetlands, ? fossil (Simpson) ! off Loch Ryan, 28f, ? fossil 

 (J.T.M.). Undoubted recent specimens have been dredged by the 

 Scottish Fishery Board off the Shetlands'in iiif and i55f. (Simpson)! 



A specimen of M. basistriata Jeff, has been dredged off the Shet- 

 lands in i55f., and two specimens between the Orkneys and the 

 Faroes (Simpson) I 



A fresh but dead specimen of Olivia otaviana Cant, has been 

 dredged between the Orkneys and the Shetlands in i45f (Simpson) ! 



Trochus helicinus var. fasciata Jeff.— Benbecula. 



T. grcenlandicus var. dilatata Jeff. — This is the normal form 

 at Tromso (Schneider) ! Vadso (Verkriizen) ! and Holsteinborg in 

 Davis Strait ('Valorous ' Expedition) 1 



T. olivaceus Brown. — Dredged by Mr. MacAndrew in 2o-3of. in 

 Skye (Jeffreys).^ Jeffreys does not say how many specimens were 

 dredged here, nor if alive, but as it is a fossil of the Clyde beds, its 

 recent identity is desirable. The Rev. A. H. Cooke, in h.is list of the 

 MacAndrew Collection, contained in the Cambridge University 

 Museum, merely repeats "Sound of Skye."' 



T. cinctus Phil. — A young specimen off the Shetlands in i55f., 

 and several off the Faroes in 80-85 f (Simpson) 1 



The discovery of this pretty little shell in British waters occurred 

 under amusing circumstances, while Gw)'n Jeffreys, with Mr. Waller 

 and another gentleman, had been dredging in the Shetlands for some 

 weeks with very poor results. One night Mr. Waller, finding himself 

 unable to sleep, came up on deck at two a.m., and as it was broad 

 daylight and the circumstances appeared favourable, with the help of 

 the night-watch he let down the dredge. After an interval, he hauled 

 in again and examined the results, and then, rushing to the cabin 

 stairs, excitedly called on Jeffreys and the other gentleman to "tumble 

 up." They immediately hurried up in their night-shirts (there were no 

 pyjamas in those days), and were greeted with the sight of several 

 living specimens of T. cinctus, which were afterwards considerably 

 added to by several good hauls. 



T. magus var. conica Marsh. — My record of this variety from 

 Heacham in Norfolk was an error, and must be disregarded. 



T. lineatus Da C— Many specimens are turbiniform instead of 

 conical, owing to the last whorl being constricted, 

 var. minor Jeff.— Torbay. 



T. striatus L. — Mediterranean specimens differ from British in 

 that they are higher and narrower, the base more convex, and the
