The cephalothorax is armed , as usual , with an acute 

 autennal tooth and the fronto-lateral angle is rounded. 

 The telson, which is somewhat shorter than the uropoda, 

 presents on its upper surface six or seven pairs of small 

 spinules and some others are found on its posterior mar- 

 giu. The peduncle of the upper antennae is a little shorter 

 than the antennal scales and reaches as far forward as the 

 spine on the lateral margin of the latter; the second joint 

 is a little longer than the third and a little shorter than 

 the first. The lateral spine on the basal joint does not 

 reach to its anterior margin and the spinule into which 

 terminates the lateral margin of the basal joint, measures 

 scarcely a fourth of the length of the second joint. The 

 peduncle of the outer antennae reaches nearly to the distal 

 end of the penultimate joint of the peduncle of the upper 

 antennae. The outer foot-jaws scarcely reach as far forward 

 as the antennal scales. 



The anterior legs reach as far forward as the rostrum 

 and fully resemble those of Car. typus M. E. The wrist, 

 which is scarcely shorter than the merus , has the same 

 form as in Car. typus; it is conical, deeply exca- 

 vated at its distal extremity and here nearly 

 as 'troad as it is long (fig. 7). The hand is a little 

 longer than the carpus, and the fingers, hairy at the ends 

 as usually, are slightly longer than the palm. The legs of 

 the second pair (fig. 7^) are reaching to the middle of the 

 terminal joint of the anten nular peduncle. The carpus is 

 twice as long as that of the first pair, slightly excavated 

 at its distal end and about five times as long as it is broad 

 at the distal end. The hand is almost as long as the wrist, 

 and the fingers, hairy at their tips, are twice as long as the 

 palm. The legs of the third pair extend a little beyond the an- 

 tennal scales, the fourth reach beyond them with their dacty- 

 lopodites and the fifth are scarcely shorter. The meropo- 

 dites of the three posterior pairs of legs are armed with 

 four (or five) small spinules. The dactylopodites of the third 

 aud fourth pair are similar to those of Car. Weberi', those
