Its distinction was first recognised by Steenstrup, and 
afterwards by Sars. 
Hab. Coasts of Norway; Greenland; Britain, &c.

L. octoradiata, Lamarck; Steenstrup; Sars. 
L. auricula, J. Rathke; Montagu; Sars; Johnston; 
Milne-Edwards. 
Bell rather deeply infundibuliform, with eight short, equi- 
distant arms. LHight large marginal papille between the 
arms. Stem equal in length to the depth of the bell. 
Length 30 mm. 
This species has hitherto been confounded with L. auricula, 
O. Fabric. ; for although Lamarck, who gave it the name of 
octoradiata, regarded L. auricula, Fabr., as synonymous 
with LZ. quadricornis, Miill., subsequent writers considered 
his L. octoradiata as a synonym of L. auricula, Fabr. 
Steenstrup was the first to clear away this great confusion. 
Hab. Norway; British Channel, both sides; Holland ; 
South Greenland, and the Faroe Islands.

Bell rather deep, infundibuliform, with eight equidistant, 
long arms. Stem scarcely as long as the bell is high, and 
not containing any muscles. Length 45 mm. 
Hab. Shores of the British Channel and south of England, 
_ to which it appears to be confined. 
This species, though accurately described by Lamouroux, 
has been often confounded with L. octoradiata.
