Mr. T. Scott (Report Fishery Board Scotland, 1889, 
p. 325) has procured a specimen of this species in the towing- 
net off lnchkeith 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 { c Challenger ’ Report) says, u There is in the 
collection of the Museum d’Histoire Naturelle of Paris a 
specimen from Falmouth presented by Leach.” Leach cer- 
tainly procured it living off the coast of Mull in 1811 ( vide 
Forbes and Hanley, L British Mollusca,’ vol. iv. p. 292). 
It is the Clio retusa of O. F. Muller, Clione papilionacea 
of authors, Clio miquelonensis of Rang, Clione elegantissima 
of Hall, and Clione Dalli of Krause. 
Very abundant in the Arctic seas. The British localities 
are its most southern limit in the Eastern Atlantic, w 7 hile in 
the Western Atlantic it was found in 1833 as far south as 
New York. It has been taken in Finmark, but is not known 
to reach the Norwegian coast.
