 wliiili is so very iiiiporfoctly drawn as to make it unwise to trust to 

 it ; but tliougli incorrect, it eWdently docs not belong to the genus 

 Phronima, and appears to diiier from the preceding species of this 

 genus.

 longs to this genus, and probably to tliis species.

 the next joint ; carpus oblong, ti'iangular, straight and dentate 

 within ; propodos longer than the carpus ; dactylos rather long.
