Diagn. Caput segmentis tribus prirais perjei paullulo longius. Segmenta duo priora percei segmento 

 tertio abrupte multo altiora. Processus tibialis pedum perm secundi paris dimidio stipitis 

 carpi multo brevior. Pedes quinti paris pedibus quarti paris multo breviores; carpus lati- 

 tudine longitudinem asquans; processus carpalis tuberculo marginis itiferioris paullulo lon- 

 gior; tuberculus latus, tridentatus; metacarpus tuberculo carens. Femur pedum septimi paris 

 femoi*e pedum sexti paris haud longius. Latera segmentorum plei post rotundata. Ramus 

 internus pedum uri secundi paris ramo externo paullo longior. 



The head is a trifle longer than the first three peraeonal segments together. The first two 

 pergonal segments are abruptly much deeper than the third. The tibial process of the 

 second pair of peraiopoda is much shorter than half the stem of the carpus. The fifth 

 pair are much shorter than the fourth; the carpus is as broad as long; the carpal process 

 is a little longer than the tubercle on the under margin of the joint; the tubercle is broad, 

 and is three-pointed; the metacarpus wants a tubercle. The femur of the seventh pair 

 is scarcely longer than that of the sixth. The lateral parts of the pleonal segments are 

 rounded behind. The inner ramus of the second pair of uropoda is a little longer than 

 the outer.
