A young male aud a female, which are of the same size. 



The female is ova-bearing. The whole upper surface of 

 the cephalothorax presents the small impressions and grooves 

 that are characteristic to this species , whereas , according 

 to Milne Edwards , only the anterior part should be covered 

 with them. In the male the right chelipede is the larger, 

 in the female the left. The extremities of the fingers are 

 scarcely excavate.

One male and an ova-bearing female from Upolu. 



I have already said (1. c.) that Lophozozymus superbus 

 A. Milne Edwards is a species different from Lophozozymus 

 superbus Dana , the latter being identical with Lophozozymus 

 incisus M. Edw. The cephalothorax of Loph. superbus A. 

 Milne Edw. attains a breadth of 55 mm. ; our two indivi- 

 duals from Upolu have , however, only half that size , though 

 the female is already provided with eggs. The chelae of 

 the female are equal in size, the upper margin of the 

 palm is slightly and obtusely carinated along its proximal half 

 and the fingers are slightly grooved in a longitudinal
