The carapace is covered with large granulations, 

 between which are fine points. The regions are well 

 marked ; the interorbital portion is taken up by the 

 epigastric lobes, which are cut off from the rest of the 

 body by a transverse groove uniting the two fissures of 

 the superior orbital border ; the hepatic region has a 

 slightly projecting lateral spine; similar smaller spines 

 border the branchial regions. The anterior cardiac lobe 

 is circumscribed behind and on the sides by a deep 

 depression in the form of a trench, inside smooth and 

 edged with a granular ridge on each margin. This trench 

 is incomplete in front ; the circumscribed lobe is flat and 

 granular. The two rostral horns are small and a little 

 flattened in their free portion. They have no granula- 

 tions. The prsocular spines scarcely reach the level of 

 the division of the rostral horns. The superior orbital
