carpus is longer than the carpus, feebly tapering towards the apex, the margins are srnooth. 

 The dactylus is long, feebly curved, smooth, almost half as long as the metacarpiis. 

 G lan ds in all the joints. 



The ph'011 is about as long as the whole perteon, the first segment is considerably 

 longer than tlie last two pera^onal segments together. The lateral parts of the pleonal 

 segments are deep, evenly rounded below. 



The peduncles of the pleojjoda are very large and thick, longer than the rami; the 

 outer ramus has ten joints, the inner nine. 



The uru.'<; the first joint is longer than the last coalesced one. The whole urus is 

 longer than the last pleonal segment. 



The /zr.si |)mV of uropoda (Pl. VII, fig. 31) do not reach to the apex of the last pair; 

 the pednncle is somewhat broader at the apex, nearly three times as long as broad, and a 

 little longer than the inner ramus; the outer ramus is somewhat shorter than the inner 

 one, the outer margin is smooth, the inner sparingly set with fine, spine-like teeth; the 

 inner ramus is armed in the same manner on both margins. The ftecond, pair reach 

 almost to the apex of the last pair; the peduncle is considerably broader below than above, 

 three times as long as broad at the apex, and much longer than the inner ramus; the 

 outer ramus is shorter than the inner one; both rami are armed as those of the first pair. The 

 third i^air have the peduncle broader than in the preeeding pairs, not twice as long as 

 broad, but considerably longer than the last ural segment; the outer ramus is longer than 

 the inner one, both margins are set with fine, spine-like teeth; the inner ramus is a little 

 longer than the breadth of the peduncle, armed as the outer one. 



The telson is triangulär, with curved margins, as long as broad; it is shorter than 

 the breadth of the peduncle of the last pair of uropoda.
