0/Z AVALTER E. COLLINGE. 



am acquainted with this is a well-marked character (cf. 2, 3). 

 The uropoda and the elongated form of the telson at once 

 serve to distinguish C. reticulatus from any other species. 

 Other differences are present in the form of the cephalon, the 

 antennee, and the 2nd maxillae. 



3. Cubaris burnupi n. sp. PI. XLI, figs. 1-10. 



Body oblong oval, strongly convex, smooth dorsally. 

 Cephalon (PL XLI, figs. 1 and 2) small. Hanked by the 

 pleural plates of the first segment of the mesosome, anterior 

 margin well defined, lateral lobes small ; epistome dorsally 

 sloping, remainder slightly convex. Eyes of moderate size, 

 situated dorso-laterally. Antennulai (fig. 3) short and robust, 

 3-jointed, with few seta3 on the distal joint. Antennas 

 (figs. 4 and 5) short, setaceous, 2nd to 5th joints, grooved on 

 their outer side ; flagellum 2-jointed, the distal joint being a 

 little over twice as long as the proximal one. First maxillaa 

 (fig. 6) with outer lobe terminating in four stout curved 

 spines and five more slender ones on the inner side. The 

 segments of the mesosome strongly convex, the 1st segment 

 Avith large expanded pleural plates, anterior and posterior 

 angles pointed ; medially the segment is produced forwards 

 (fig. 7), pleural plates of 2nd to 4th segments excavate, 

 remainder truncate or nearly so, posterior angles very slightly 

 produced backwards. Segments 1 and 2 with notch and 

 groove on the underside of the inner margin (fig. 8). Uro- 

 poda (fig. 9) not extending beyond the telson, ventrally 

 concave, basal plate thick, strongly raised and convex dorso- 

 laterally, posterior margin truncate, antero-dorsal surface 

 expanded ; exopodite small, not extending beyond the inner 

 margin of the basal plate, endopodite slightly more than 

 twice the length of the exopodite, setaceous. Telson (tig. 10), 

 posterior margin wider than the length, almost truncate, 

 lateral margins curved, convex, and smooth. 



Length 14*5 x 8 nnn. 



Colour (in alchohol) greenish-brown, with lighter irregular
