species, supposed by Willughby * 1 ' and Ray d to be also 
known to the Cornish fishermen under the name of 
Lantern. The deciduousness of the scales and the thinness

characters. As we now propose to show, it is as yet

impossible to decide with entire certainty whether more 
than one species of this subgenus is known in Europe; 
and we find the same difficulty with regard to the 
non-European species. Bleeker, however, has described 
5 species from the East Indies, one of which, Arno- 
glossus tapeinosoma, was taken off Hong Kong by the Vega 
Expedition, on a clayey bottom in 22 fathoms of water".
