Plate 22, fig. 4 j 



Description. — Shape of carapace similar to that of R. vaderensis, ; 

 but the anterior half is more oblong, the widest part in front of | 

 middle, the fronto-orbital width greater, the antero-lateral spine fur- i 

 ther forward, the lateral margin not so strongly outcurved behind 

 the spine; postero-lateral margin straighter; the dorsal surface more 

 convex, so that in dorsal view one can scarcely see the lateral margins. 

 Very little of the outer layer of shell remains, it shows roughness , 

 near the antero-lateral margin ; the layer just below is rough with I 

 fine granules in front which gradually diminish in size until the I 

 posterior end is nearly smooth. Merus of cheliped little more than | 

 twice as long as wide, outer margin very convex. j 



Measurements. — Holotype, length of carapace to posterior end of ' 

 inner frontal sinus 28.3 mm. ; greatest width of same 19 mm. ; width | 

 at posterior base of antero-lateral spines 17 mm. ; fronto-orbital | 

 widtli (tips of spines broken off) 13.5 mm. j
