the distance between suborbital spines narrower, but this character is 

 not constant, varying in the region where the two forms meet.

 inner side of the carpus and a few tubercles on the chela which are 

 dark brown in many specimens (Smith).

 greatest width of same 46, fron to-orbital width 20.9, width of orbit 

 7.7, width between suborbital spines 6.6 mm. Largest specimen, 

 female (8856), extreme length of carapace 52, greatest width of same 

 63 mm.

 (Seba).

' In my previous use of the specific name hipustulatus instead of punctatus it was considered that Corystes 

 (Anisopus) punctata was a nomen nudum in 1833 and should give way to Platyonichus bipustulatus 1834. 

 Subsequently it was brought to my notice by Stebbing (S. Afric. Crust., pt. 2, 1902, p. 14) that the species 

 punctata was sufficiently defined by de Haan under the subgenus Anisopus, where he described the peculiar- 

 ity of the dactylus of the second pair of trunli legs, a character not shared by ocetlatus, the only other valid 

 species of the genus.
