Closely resembling the typical form of kergueleni in pleon seg- ments 3 and 4, but apparently a larger species. In other respects generally re- sembling kergueleni but inner lobe of maxilla 1 with six plumose spine setae, and epistome produced in a convex, but somewhat flattened lamina from between -''' a. 6. the bases of the 2nd antennae to the pig. 14.
