only 13 mm. long, and very insignificant in bulk compared 

 with the first, the rostrum again is little longer than peduncle 

 of the first antennae, but it has only one ventral tooth in 

 addition to that of the apical trio, both the other members of 

 which reach beyond it, the median tooth greatly exceeding 

 both its partners. In the smaller specimens the flagella of the 

 first antennae might justify Stirnpson's characterization of 

 them as subequal, but in the largest specimen the more 

 slender flagellum is considerably the longer. The flagellum of 

 the second antennae appears to be as long as the body ; the 

 scale is broad, the apical tooth of the outer margin not 

 nearly reaching the end of the broadly rounded setose distal 

 border. 



The mandibles have a strong molar, the incisor process 

 weak, ending in five little teeth. First maxillae with a short 

 twisted palp. Second maxillae with lowest lobe receding, 

 fringed with a few long setae, apical plate bent, tipped with 

 one spine. First maxillipeds with the slender distal part of 

 the endopod rising from a broad membranaceous base. Finger 

 of second maxillipeds short, broad, with fan-like fringe of 

 slender spines. 



First peraeopods short, stout, fingers shorter, wrist rather 

 longer than palm and subequal to the fourth joint. Second 

 peraeopods, with wrist subequal to fourth joint, its proximal 

 division as long as the other two combined, the third longer 

 than the second. Fifth peraeopods having the finger fringed 

 with 8 graduated spines, the largest adjoining the unguis, 

 which is backed by a spine slightly longer and more 

 slender. 



Postero-lateral angles of the sixth pleon segment acute. 

 Outer ramus of the uropods broad, its outer margin smooth, 

 ending in a small tooth, within which is a large spine, the 

 distal border of the ramus extending some way further, fringed 

 with setae. The elongate telson has two pairs of dorso- 

 lateral spines, as stated by Stimpson, but also three pairs of 

 different sizes on the apex. 



Localities. Knysna mile above jetty. A 1282. A 

 specimen, ovigerous female, from East London, sent to the 

 Museum by Mr. Wood, agrees with the largest of the three 

 specimens described above exactly in the rostral character, 

 and has a total length of 32 mm. A 128] .
