Sesanna miniata .... Saussure. 



Carapace scarcely curved, flat, and slightly convex, 

 presenting only a groove which indicates the genital 

 regions posteriorly. 



Frontal lobes slightly elevated, without central groove. 

 Front less than half the length of posterior border of the 

 carapace, less vertical, but longer from above downwards, 

 having some small elevations, especially under the median 

 lobes. Towards the arm it becomes slightly wider from 

 the lateral angles advancing a little laterally, so that the 

 inferior border is wider than the superior portion. The 

 orbits notch slightly the frontal crest. The branchial 

 regions are folded, but not on the anterior portion of 

 the carapace, where there is no trace of ridges. All the 

 carapace is covered with small pits, each pit holding a 

 black hair, and scattered larger ones holding three or four 

 hairs. The sides have no teeth behind the external orbital 

 tooth. Fourth joint of external maxillipedes punctuated, 

 except on the internal marginal portion, which is wide. 



Legs covered with large punctuations or scales, 

 especially upon the fourth joint. Sixth joint of the 

 fourth and fifth pair thin. The first pair of legs short, 

 large ; the fifth joint large, granular, and has hairs. 

 Hands short, swollen, smooth, and punctuated.
