Carapace much depressed, perfectly flat above, with the 

 surface nearly smooth centrally and very finely and closely 

 granular laterally, and with the regions indistinctly defined. 

 The front has the form of a horizontally projecting bilobed 

 lamella, with the free edge sharply and \cYy evenly spinate 

 and the sides turned abruptly downwards. The margins of 

 the orbit are spinulate, the upper margin the more distinctly 

 so, and the lower margin terminates internally in a strong 

 oblique spine, the point of which inclines towards the sharply 

 vertical tooth formed by the already mentioned downfolding 

 of the lateral edge of the frontal lamella. 



The antero-lateral borders of the carapace, which are 

 arcuate and are shorter than the postero-lateral, are armed 

 with three large spines, in front of, between, and behind 

 which are several s pinnies. The pterygostomian regions are 

 large and inflated^ and the branchial apertures, especially the 

 efferent aperture, are large and patulous. 



The eye-stalks are large and are of moderate length ; the 

 corueal region is rather small.
