Mr. T. Scott (Report Fishery Board Scotland, 1889, 

 p. 325) has procured a specimen of this species in the towing- 

 net ofi" Inclikeith in the Firth of Forth, which he kept alive 

 for two days ; and Professor M'Intosh records that on April 

 11 and 12, 1887, and during a week or two afterwards, a 

 considerable number of the species were captured near shore 

 at St. Andrews. 



Pelseneer (' Challenger ' Report) says, " Tiiere is in the 

 collection of the Museum d'Hi.stoire Naturolle of Paris a 

 p])ecinien from Falmouth presented by Leach." Leach cer- 

 tainly procured it living otf the coast of ^lull in 1811 [vide 

 Forbes and Ilanley, ' British Mollusca,' vol. iv. p. 292). 



It is the Clio retusa of O. F. JMiiller, Clione papilionacea 

 of authors, Clio miquelonensis of Rang, Clione ele(jantifisima 

 of Dall, and Clione Dalli of Krause. 



Very abundant in the Arctic seas. The British localities 

 are its most southern limit in the Eastern Atlantic, while in 

 the Western Atlantic it was found in 1S.>3 as far south as 

 New York. It has been taken in Finmark, but is not known 

 to reach the Norwegian coast.
