580 WALTER E. COLTJNGE. 



(fig. 27) with short outer lobe, terminating in two rhulti- 

 spinous processes and a single small spine, inner lobe with 

 three tooth-like spines and one elongated one. The segments 

 of the metasome have the pleural plates produced backwardly 

 as sharp spines (fig. 30). Uropoda extending beyond the 

 telson, basal plate raised on the dorsal surface and expanded 

 on the inner side, ventrally it is produced as a blunt spine on 

 the outer anterior margin, and with a thickened rim on the 

 inner margin ; endopodite small and cuneiform, setaceous ; 

 exopodite rather short and stout, flattened on the outer side, 

 setaceous. Telson (fig. 81) small, lateral margins rounded, 

 terminally rounded with deep sulcus in the mid-dorsal line. 



Length 10"5 mm. 



Colour (in alcohol), the pleural plates and the posterior 

 border of the segments are a dark brownish-green, whilst the 

 cephalon and the middle and anterior portion of the segments 

 are marked Avith irregular oval yellow patches. 



Habitat. — Pentrich, near Pietermaritzburg, Natal, Sep- 

 tember 14th, 1915. (C. Akerman.) 



Type. — In the Natal Museum. 



This beautifully-marked species is removed from the typical 

 Philoscia by a number of important characters, such as 

 the form of the cephalon, the stunted outer lobe of the 

 maxillipedes, the uropoda, telson, and the backwardly pro- 

 duced pleural plates of the metasomatic segments. There are 

 other allied species in the collection, which, when examined, 

 may help in rightly placing them.
