107, 1911. Bate, in the “Challenger” Macrura, introduced the 
species as a variety of Pencus canaliculatus, Olivier, 1811. 
The specimen sent me by Mr. Bell Marley, from the sand-banks of 
Durban Bay, measures 116 mm. from apex of rostrum to the tip of 
the telson. In the central line of the carapace it has eleven dorsal 
teeth, and there is a single ventral tooth to the rostrum, which itself 
coincides in extension with the lateral tooth of the antennal scale. 
For the sulcate acute-ending telson, Mr. Bell Marley gives the colouring 
when fresh as dark red in the middle, pale brown proximally, and 
distally white; and for the uropods a succession of white, dark red, 
white, yellow, pale blue, with a fringe of carmine sete. The specimen, 
as preserved, is still suggestive of its decorative appearance when alive. 
Date of capture: 26th July, 1917.

PROCESSA sp. 
Along with numerous other species of small size from the sponge 
Cerao chalinus, was a specimen of the genus Processa, measuring only 
6 mm. in length. After dissecting and drawing some of the details 
I gave up the hope of deciding whether this was a young form of 
P. canaliculatus, Leach, or deserving of some other specific designation. 
The short rostrum has a setule on each side of the acute apex. ‘The 
telson carries three pairs of dorsal spines, with three pairs on the 
apical margin, the outermost small, the middle pair shorter and more 
slender than the intermediate pair. Of the short first pereeopods only 
one is chelate; of the very slender second pair both members are 
elongate, but unfortunately one had its termination imperfect. In 
the first antenne the first joint of the peduncle is longer than the 
second and third combined, the second is shorter than the third. The 
palp of the first maxilla is as figured by de Haan for “ Vika edulis” ; 
the exopod of the third maxillipeds is not one-third of the length of 
the long antepenultimate joint; the terminal joint is spinose. The 
figures in de Haan are evidently not to a uniform scale.
