Diagnosis. Abdomen and sternum showing prominent laminae 

 behind carapace in dorsal view. Three subequal antero-lateral teeth, 

 Inner suborbital lobe trilobed, inner sinus large. Carapace one- 

 fourth to one-third wider than long; a sinuous posterior line of 

 tubercles. 



Description. Carapace rather evenly but not strikingly convex, 

 regions not deeply marked, granules of different sizes, sometimes 

 clustered to form tubercles. Front very broad, not prominent, 

 median teeth small, tuberculiform, median sinus a narrow V, lateral 

 sinuses a little wider, shallow, rounded, lateral lobes shallow, 

 rounded. Middle supra-orbital lobe broad, truncate, followed by a 

 sinus rounded at base; outer lobe narrower, lobiform, separated by 

 a shallow V-sinus from outer orbital tooth; this last is blunt and 

 directed forward. Antero-lateral teeth three, small, distant, first 

 tooth remote from orbit and from the second which is nearer the 

 third. Above posterior margin a very sinuous line of tubercles. 

 Lower margin of orbit very oblique, divided by a wide V into two 

 lobes, the outer straight and rightangled, its inner margin concave, 

 inner lobe with three marginal crenulations, inner angle subacute. 

 Pterygostomian lobe very broad, bluntly obtusangled at tip, con- 

 cealing in ventral view all but outer end of inner orbital lobe. 



Chelipeds feeble and equal in both sexes, slenderer in female than 

 in male. 



First leg very short and slender, merus little rough and with a 

 small, obtuse distal tooth ; second and third legs with merus coarsely 

 spinulous, especially along anterior margins, antero-distal angle 

 almost rectangled, subacute; carpus very long and narrow, anterior 

 lobes low; propodus sensibly widening distally; dactylus with 

 posterior margin sinuous. 



The most striking feature of this species is the arrangement of 

 abdominal and sternal plates behind the carapace; first three seg- 

 ments of abdomen are carinated, the first carina has a shallow lobe
