twice as long as the first, fourth joint about equal to the first three 

 combined, fifth rather shorter, flagellum fifteen-jointed, longer than 

 the peduncle. 



The lips showed no exceptional character, unless the difficulty of 

 detaching them from the oesophagus could be so accounted. 



The mandibles have a prominent molar with denticulate circular 

 crown. On the left mandible a very small strap-shaped accessory 

 cutting plate is seen, and a spine-row of two very small spines. The 

 inner plate of the first maxillae carries two unequal setae, the serrate 

 spines on the outer plate and the spine-teeth on the long second joint 

 of the palp are all very short. In the second maxillee the outer 

 plate is somewhat longer and broader than the inner. Both the 

 inner and outer plates of the maxillipeds are rather long, the outer 

 fringed on the inner margin with nine spine-teeth, of which the 

 lower ones ai~e distant and very small. This plate reaches beyond 

 the second joint of the palp. 



The gnathopods are not powerful. In the first pair the third joint 

 is about as long as the fourth, the fifth rather longer than the sixth, 

 which widens slightly to the very oblique palm. This is a little 

 overlapped by the finger when closed. The tip of the finger 

 has a small cap, which is also the case in the first and second 

 perseopods. In the second gnathopods the third joint is considerably 

 longer than the fourth, and the fifth than the rather stout sixth, of 

 which the palm is faintly excavate. The small finger is apically 

 bidentate. Whether the branchial vesicles of these limbs have an 

 accessory lobe was not made out. The lobes attain their greatest 

 development in the third and fourth peraeopods. The marsupial 

 plates of the specimen figured were very narrow. 



The first and second perseopods are similar, slender throughout. 

 The three following pairs have the second joint strongly expanded, 

 but only feebly serrate. In the third and fifth pairs this joint is 

 proximally almost as broad as the length, in the fourth pair its 

 breadth is much more uniform and considerably less than the length. 

 The fourth joint in the third pair is nearly as broad as long, other- 

 wise all joints but the second are moderately narrow. 



The pleopods have two little coupling hooks, a few cleft spines, 

 and the branches about seventeen-jointed. The uropods have but 

 few spines on the rarni, which in each pair are subequal, longer 

 than the peduncle only in the third pair ; in this the outer branch 

 has a well-marked second joint, and the inner branch is longer than 

 the first joint of the outer. 



The telson is divided nearly to the base, with a spine in the apical
