of ramus ; peduncle of uropods very broad, outer ramus narrower 

 but not shorter than inner. 



Very similar to Pontogelos, Stebbing (Tr. Linn. Soc. Lond. 

 vol. 14, pt. 1, p. 97, 1910), especially as regards the mandibles and 

 maxillipeds, but differing in the antennae, second maxillae, uropods 

 and peraeopods. 



PONTOGELOIDES LATIPES, n. Sp. 



(Plate XXX. C.) 



Body very convex, smooth. Head with small median rostrum 

 meeting the frontal lamina, which is narrow, anteriorly broader than 

 posteriorly, in side view strongly curved ; eyes oval, black, in the 

 lateral angles. Peraeon segments 4-7 with a low transverse carina 

 running a short way across the segments from the middle of the 

 sutures with the epimera. Epimera without oblique grooves, rather 

 broad, postero-lateral angles subacute but not produced. Pleon 

 equal in length to peraeon segments 2-7 together. Telson rounded, 

 broader than long, margin minutely serrulate apically, with a few 

 plumose setae. 



First antenna reaching to posterior margin of 1st peraeon segment, 

 anterior margin of 1st joint produced along the 2nd joint, but not 

 directed forwards, 3rd joint nearly as long as but much more slender 

 than 2nd joint, flagellum thrice as long as peduncle, 16- or 17- 

 jointed. 



Second antenna subequal to first antenna, peduncle 5- jointed, very 

 stout, inner margin of 4th joint and inner apex of 5th joint with long 

 setae, flagellum scarcely as long as peduncle, 12-jointed. 



Epistome (clypeus) triangular, prominently projecting. 



Upper lip transverse, 2J times as broad as long, distal margin 

 excavate. 



Mandibles with cutting-edge tridentate, molar as in Cirolana, palp 

 2-jointed, 2nd joint nearly thrice length of 1st joint, apex rounded 

 with 3-4 long setae. 



First maxilla normal, outer plate with 11 spines, inner plate with 

 3 plumose setae. 



Second maxilla normal, outer and middle plates a little narrower 

 than inner plate, each with ca. 9 setae, the inner plate with several 

 stout plumose setae and smaller simple setae. 



Maxilliped, 2nd joint (in $ ) twice as long as broad, 4th and 5th 

 joints broad, all joints strongly setose, inner plate narrow, equal in 

 length to 2nd joint, tapering to a blunt point with 2 small plumose 

 setae, outer margin with ca. 8 strong plumose setae, inner margin
