THE TEKltESTIilAL [SOPODA OF NATAL. 569 



forms are fairly widely separated from one another, and few 

 of them have been fully figured or described. The new 

 species here described and figured show little relationship to 

 the above-mentioned species or to species known from else- 

 where (2, 3). Budde-Lund (12) has suggested placing all the 

 South African species in the genus Diploexochus Brandt, 

 but Brandt's description (4, p. 191) is so very vague that I do 

 not at present feel inclined to follow him. 



1. Cubaris warreni n. sp. PI. XL, figs. 1-10. 

 Body oblong oval, convex, surface with small irregular 

 rugosities in the middle of each mesosomatic segment and 

 raised oval areas laterally ; metasome finely granulated. 

 Cephalon (PI. XL, figs. 1 and 2) small, flanked by the pleural 

 plates of the first mesosomatic segment, anterior margin 

 raised, lateral lobes small ; epistome dorsally sloping, raised 

 in the median line and sunken laterally. Eyes large, situated 

 dorso-laterally. Antennulfe short and robust, 3-jointed, Avith 

 few lateral seta? on the terminal joint. Antennaj (figs. 3 and 

 4) short and slender, setaceous, 2nd to 5th joints slightly 

 grooved on their outer side ; flagellum 2-jointed, the distal 

 joint being two and a half times the length of the proximal 

 one ; style elongated with few terminal setae. First maxillae 

 (fig. 5), outer lobe terminating in four stout curved spines 

 and six finer inner ones, with long setae on the outer lateral 

 border ; inner lobe rounded distally and with two setose 

 spines. Second maxillee thin and plate-like. The segments 

 of the mesosome convex, the 1st with expanded pleural plates, 

 anterior and posterior angles acutely pointed, pleural plates 

 of the 2nd-4th segments slightly excavate and their 

 posterior angles produced backwardly, 5th-7th bluntly 

 I'ounded with the posterior angles produced on the 5th and 

 6th. Notch and groove on the underside of the inner 

 margin of segments 1 and 2 well developed (fig. 7). Maxilli- 

 pedes (fig. 6) with outer lobe terminating in a multispinous 

 process and two fine spines, inner lobe with three tooth-like 

 spines. Uropoda (figs. 8 and 9) not extending beyond the
