574 WALTETJ K. fiOLLlNGE. 



almost straight, expanded anteriorly, convex and smooth, 

 posterior margin truncate. 



Length 7 "5 mm. 



Colonr (in alcohol) a horny brown with six to seven small 

 whitish markings on each side of the mesosomatic segments. 



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

 Warren.) 



Type. — In the Natal Museum. 



This is a very distinct type and easily recognised by the 

 form of the cephalon and the stout uropoda. 



5. Cubaris longicauda n.sj^. PI. XLI, figs. 21-31. 



Body oblong oval, convex, dorsal surface finely granulated. 

 Cephaion (PI. XLI, figs. 21 and 22) small, flanked by the 

 pleural plates of the first segment of the mesosome, anterior 

 margin distinct, lateral lobes small; epistome almost verticiil. 

 Eyes fairly large, situated dorso-laterally. Antennula^ 

 (fig. 23) short, o-jointed, with few lateral setae on the distal 

 joint. Antennae (figs. 24 and 25) rather longer than usual, 

 otherwise typical of the genus. First maxilla^ (fig. 26), outer 

 lobe terminating in four stout curved spines and six pointed 

 smaller oues, inner lobe with trilobed head and three setose 

 spines, body indented on the inner side to form a trilaminnte 

 border. Second maxilhe (fig. 27) fiat with setose inner lobe 

 with two spines at the base, outer lobe terminating somewhat 

 crenate, and with setje on the inner side. The segments of 

 the mesosome (fig. 29) have the pleural plates well developed 

 with the posterior angles pointed and pi^oduced backwards. 

 The notch or tooth on the inner margin of the underside of 

 the 1st segment is very feeble, whilst the groove on the 2nd 

 segment is represented by a slight thickening (fig. 29). 

 Maxillipedes (fig. 28), lobes somewhat stunted and robust. 

 Uropoda (fig. 30) not extending beyond the telson, ventrallv 

 slightly concave, basal plate thick, convex, and strongly 

 raised dorso-laterally, posterior margin bluntly rounded, 

 antero- dorsal surface strongly thickened, setaceous ventrally.
