of the exopodite has a round process at the base of the inner margin, 

 and the mobile spines on the outer margin in either uropoda are seven 

 in number. 



The corneal region of the eye is somewhat widened. The dactylus 

 of the raptorial limb is strongly dilated at the base, where a slight 

 dentation occurs on the outer margin. 



This species undoubtedly resembles P. glabra Lenz, but may be 

 readily distinguished by the presence of the depressions upon the last 

 two somites, etc. 



Colour. — In the alcoholic specimen the ground colour is reddish 

 brown, on which some dark purple markings are present upon the 

 dorsal surfaces of the longest segment of the raptorial limb as well as 

 of the exposed thoracic and the abdominal segments.
