In the present confused state of our knowledge it is scarcely necessary to enumerate 

 the many localities from which 5. nepa has been reported. It is clear from the series 

 in the Indian Museum that the species is distributed over a very wide area ranging 

 from Hongkong to Karachi. Most of the records subsequent to 1894 may very reason- 

 ably be regarded as correct and, if this should prove to be the case, the known distri- 

 bution extends from Honolulu (Lenz) to Madagascar (Lenz) and Durban (Stebbing).

 This species is very closely allied to the preceding, but may readily be distinguished 

 from it by the following well-marked characteristics : — 



1 . The median carina of the carapace in front of the cervical groove is bifurcated 



anteriorly for less than one third of its length and is finely bicarinate through- 

 out the greater part. of its entire extent (fig. 51). 



2. The lateral margins of the rostrum are rather more strongly convergent an- 



teriorly and the apex is more rounded (fig. 50).
