the fifth joint of the second pair of feet shorter than the chela, 

 not longer as in P. idee, and for further distinction the fingers 

 are not short but as long as the palm, armed with two rows of 

 tubercles, and the chela covered with hairy felt. Hilgendorf him- 

 self recognised the close approximation of his species to Heller's 

 P. rudis, but found the chelae free from felt. 



A specimen from Durban agrees with the characters given by 

 Coutiere, except that the felting appears to be almost completely 

 worn off. The rostral carina, which reaches slightly beyond the outer 

 tooth of the antennal plate, has 12 teeth above and 4 below. The 

 flagellum of the second antennae is 180 mm. long, the body of the 

 creature having a length of 125 mm. The long chelipeds are almost 

 exactly equal, the fourth joint 50, the fifth 70, and the sixth 110 mm. 

 long. The finger has a length of 58 mm. The apices of finger 

 and thumb are curved and cross one another, the inner margins 

 otherwise in closure being closely applied. 



Locality. Durban. Two much smaller specimens from the same 

 waters appear to agree well with the one above noticed in general 

 character.
