 spines. The orbit is a wide and shallow cavity, the bottom 

 of which is still some distance behind the anterior margin, 

 and it is defined externally by two spines. The very distinct 

 and throughout dorsal linea anomurica runs to the base of 

 the supra-orbital spine. The carapace is decidedly macrurous

 twice interrupted by regional grooves. The last two joints of 

 the fifth pair of legs form a perfect subchela, the dactylo- 

 podite coining into complete relation with the basal toothed 

 process of the propodite.

 The sides of the head are more produced, and the consequently
