Diagnosis. — Abdomen and stern mn showing prominent laminae 

 behind carapace in dorsal view. Three siibequal 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 teetli small, tubcrculiform, median sinus a narrow V, lateral 

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

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

 sinus rounded at base; outer lobe narroAver, 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 Avhich is nearer the 

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

 Lower margin of orbit very oblique, divided by a Avide V into tAVo 

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

 inner lobe Avith three marginal crenulations, inner angle subacute. 

 Pterygostomian lobe Aery bioad, 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, mcrus little rough and with 

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

 spinulous, especially along anterior margins, antero-distal angle 

 olmost rectangled, subacute; carpus Aery long and narrow, anterior 

 lobes loAv; propodus sensibly Avidening distally; dactylus Avith 

 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
