 lamina, of which the edge forms four lobes. The anten- 

 nulary fossae are not prolonged as far as the level of the 

 posterior border of the orbits, and have a slightly raised 

 margin. The lobe placed between the fossae is notched, 

 divided by a groove, and has a tubercule on each side. 

 The superior orbital border has inside an obtuse elevation 

 placed on a level with the external orbital spine. The 

 carapace has three small spines on each side. It is
