telson, ventrally slightly concave, basal plate thick, strongly 

 raised and convex dorso-laterally, posterior margin pointed, 

 antero-dorsal surface folded, setaceous ventrally, dorsally 

 with ti'iangulai'-shaped scales ; exopodite long, but not 

 extending beyond the posterior margin of the basal plate, 

 setaceous, endopodite rather longer and broader than the 

 exopodite. Telson (fig. 10) longer than the width of the 

 posterior margin and extending a little beyond the uropoda, 

 lateral margins slightly curved, expanded anteriorly and 

 convex, sloping from the median line, with two raised bosses 

 on the anterior margin. 



Length 10*5 mm. 



Colour (in alcohol) greenish-brown, with lighter-coloured 

 mottling. 



Habitat. — Krantzkop, Natal, January 1st, 1915. (E. 

 Warren.) 



Type. — In the Natal Museum. 



This and the following species belong to a section of the 

 genus characterised by the pointed uropoda and elongated 

 exopodites. The cephalon has the anterior or frontal margin 

 deeply indented, with a sloping epistome dorsally. The 

 antentia^ are slender. The oral appendages present no charac- 

 ters of particular importance. The telson is fairly long, 

 exceeding the width of the postei'ior margin, and is raised in 

 the mid-dorsal portion to form a somewhat triangular eminence 

 with two raised bosses on the anterior margin. 



It affords nle much pleasure to associate with this inter- 

 esting species the name of Dr. E. Warren, the Director of the 

 Natal Museum.
