hepatic lobe projects obliquely forward and slightly downward; 

 close behind it shows in dorsal view the large pterygostomian lobe, 

 and in front of it the obtuse angle of the buccal cavity. 



Segments of sternuni rounded and deeply separated; in front of 

 the abdomen a rounded lobe on each side close to base of cheliped. 

 Basal antennal article strongly angled, the extremity of the ridges 

 accented. 



Chelipeds stout, bordered by long straight hairs on lower edge of 

 ischium and adjacent parts of merus, on upper edge of remainder of

cheliped (hairs directed inward), on both edges of fingers and outer 

 surface ot dactylus. Some of the spinules are clustered on tubercles, 

 as on the ischium, and the outer surface of the carpus. Distal two- 

 fifths of fingers in contact, remainder gaping, leaving an oval inter- 

 space into the middle of which an enlarged tooth of the dactylus 

 projects. 



Legs slender. First leg three times as long as the carapace, pro- 

 podus twice as long as the slender and little curved dactylus; second 

 two and a third times, third twice, and fourth one and three-fifths 

 times, as long as carapace; second, third, and fourth dactyli equally 

 curved, the second perceptibly longer; second propodus nearly three 

 times as long as its dactylus, third and fourth propodites nearly one 

 and three-fourths times their respective dactyli.
