Female. — The first antennae extend beyond the furca. The exop- 

 odites of the second antennae are composed of 7 segments. The last 

 cephalothoracic segment projects backward on the sides the length of 

 the first abdominal segment; the projections have inner lobes which 

 are rounded. The first abdominal segment is asymmetrical. In the 

 fifth feet the tenninal segments of the exopodites are armed with 7 

 spines.
