[Voi,. XXIV, 



and is supported by a carina which extends backwards to a point 

 immediately above the base of the hepatic spine. The hepatic 

 and antennal spines are about on a level with one another and the 

 antero-latera! angle of the carapace is rounded. 



(Hi) The spine on the outer side of the second segment of the 

 antenna is very long. The terminal spine of the antennal scale 

 reaches almost as far forwards as the apex of the lamella. 



(iv) The antepenultimate segment of the third maxilliped is 

 broad, scarcely more than 3 times as long as wide. 



(v) The first peraeopod is slender, with carpus about 8 times 

 as long as its distal breadth and with fingers more than half as long 

 as the palm. 



(vi) In the second peraeopod (text-fig. 68) the ischium bears 

 three distal spines, one above and two, which are smaller, below. 



The merus has a strong 

 spine at the distal end 

 of its upper border; 

 the lower border ends 

 in a sharp spine on the 

 outer ?ide and in a 

 rounded lobe on the 

 inner side. The carpus 

 has a sharp spine on the 

 upper and outer aspect 

 of the distal margin 

 and an acute process, 

 sometimes spiniform, 

 on its lower side. 

 The outer margin of 

 the dactylus is straight 

 or slightly concave 

 and on the lower 

 surface of the segment 

 there is a sharp longi- 

 tudinal carina. There 

 is a large triangular 

 tooth on the inner mar- 

 gin of the dactylus a 

 little behind its middle 

 point and at the base 

 a rounded protuberance. The tooth fits between two teeth on 

 the fixed finger, the hindmost of which is broad and frequently 

 exhibits a serrated edge. The palm is about 25 times as long as 

 the fingers. 



(vii) In the third pair of peraeopods the merus is about 

 3-2 times as long as wide. The propodus is much narrower than the 

 merus, about 6-5 times as long as wide, and at the distal end very 

 little broader than the dactylus. 



(viii) The pleura of the fourth and fifth abdominal somites 

 are acutely pointed infero-posteriorly.
