is, according to Roux, purple, washed in some parts with 

 greenish. The dactyli of the raptorial limbs, antennules and 

 antennas, and cilia of the basal antennal scales and uropoda 

 are red. 



Hab. Mediterranean. 



Having seen no specimens of this rare and beautiful species, 

 I have taken the above description from the description and 

 figure of Koux, whose examples were brought from Sicily by 

 M. Caron. A single example has quite recently been recorded 

 by Haller from Nice. In many of its characters it is allied to 

 PseudosquiUa. 



** Dactyli of the raptorial limbs armed with four spines.

Carapace elongated and narrowed anteriorly, with the cer- 

 vical suture strongly defined and deeply sinuated posteriorly ; 

 on the postero-lateral regions of the carapace are two short 

 lateral carinas ; the antero-lateral as well as the postero-lateral 

 angles of the carapace are rounded. Rostrum ovate, smooth, 

 somewhat longer than broad. The carinas on the exposed 

 thoracic and postabdominal segments are distinctly defined • 

 on the fifth postabdominal segment the lateral carinas, and on 

 the sixth all the carinas terminate in spines. On the sides of 

 each segment, between the second and third carinas, is a 

 flattened triangulate prominence ; the terminal segment is 

 armed with five longitudinal median crests, and the inter- 

 spaces with small irregular prominences • there are six strong 

 marginal spines, and in the intervening spaces numerous smaller 

 denticles. The submedian marginal spines end each in a 

 small mobile spinule. The dactyli of the raptorial limbs are 

 small and armed with three spines besides the terminal one. 

 The distal prolongation of the basal portion of the uropoda 

 terminates in two strong spines, of which the innermost is 

 curved. 



The length of this species, as given by Hess, is 17*2 centims. 

 A male specimen in the Museum is only half the size 

 (3^ inches). 



Hab. Australia, Sydney (Mus. Gottingen) • Victoria (Mus. 

 Brit.). 



In the Museum specimen the ridge between the second and 

 third carinas on the first to fifth postabdominal segments is 

 linear and oblique.
