The genus Unciola was established by Say in 1818, and adopted 

 by Milne-Edwards and other authors. Synonyms are Dryope, Sp. 

 Bate, Glauconome, p. Kroyer, and Cyrtophium, p. Danielssen. 



The species referred to the genus, as seen in the above table, 

 are: — 1. Unciola crenatipalmata, Sp. Bate ( = irrorata, Gosse, nee 

 Say), of the seas of western Europe; 2. U. irrorata, Say (= Glau- 

 conome leucopis, Kroyer, and Cyrthophium Darivinii, Danielssen), 

 from the Arctic seas and those of Britain and Norway ; 3. U. plan- 

 ipes, Norman ( = leucopes, Sp. Bate and Westw., Glauconome Kroeyeri 

 and Steenstrupii, Boeck), from the shores of Greenland, Norway, 

 England, and France ; 4. U. petalocera, G. 0. Sars, from the Arctic 

 Ocean ; 5. U. crassipes, Hansen, from the west coast of Greenland ; 

 and 6. U. latieornis, Hansen, from the same region. — Ball. Sclent.
