Bell, (the nearest ally of this species) being absent;*' lateral 

 pair much the longest, hardly appreciably flattened and slightly 

 curved upwards ; covered, in common with the others, with granules 

 like those on the surface of the carapace. Front prominent, 

 emarginate. Anterior limbs more than twice as long as the 

 carapace ; arm slender and tuberculated ; hand smooth, slightly 

 swollen at base, and tapering towards the fingers, which are very 

 slender, and armed on their inner margins with fine denticles and 

 a few larger triangular teeth. Posterior limbs slender, cylindrical 

 and smooth. Abdomen (female) ovoid, granulated ; the compound 

 part with no trace of intersegmental lines, but traversed by well- 

 marked longitudinal sulci. Colour nearly white, with a blush of 

 red over the lateral parts of the carapace and the lateral spines ; 

 and a band of the same colour on the upper surface of the arm. 



Length 5 lines ; breadth, including lateral spines, 8^- lines.
