the lobes they drop to the bottom. A second species 

 L. helicoides, was found dead at the bottom off the 

 west coast of Ireland (lat. 56° 44' N. ; long. IT 50' W.) 

 by the Porcupine Expedition, 1869. 



Clio j92/?T(7uicZafa has a beautiful triangular shell, 

 of the thinnest crystal, and half an inch in length. 

 It has been dredged to the north-east 

 and north-west of Shetland in water 

 from 60 to 84 fathoms, in one case 

 with the animal in the shell. But in 

 1869 the Flyhuj Fox off the South of 

 Ireland, found it in abundance at the 

 surface. 



The only other species that can 

 urge a slight claim to be regarded 

 as a Britisher is Clione limacma, 

 which belongs to the shell-less section and has a 

 distinct head. It is an Arctic species, and one of the 

 constituents of the food of whales. Leach captured 

 a living example on the coast of Mull ninety years 

 ago; M'Intosh reported it in considerable numbers 

 at St. Andrews in 1887, and T. Scott took a specimen 

 at Inchkeith in 1889.
