In general habitus this species is very like the preceding 
but differs in the fifth pair of pereiopoda being shorter than 
the sixth, with very short metacarpus; the seventh longer than 
half the sixth, and the last pair of uropoda being provided with 
well developed exterior rami. |

This species is readily distinguished from its congeners by

The second family Lanceolida, C. Bovallius, 1887.

First pair of antenn&e tumid. Second pair filiform, not angu: 
lated, fixed at the anterior-side of the head. Mandibles with 
palp. Seventh pair of pereiopoda not transformed. Peduncles 
of uropoda normal. 
Hitherto representants for the family are known only from 
the arctic region, but I think it very likely that Lanceola felina
