the merns, and the dactylus about three-fifths as loug as the propodus. 

 The fifth pair are considerably longer than the fourth; the merus is a 

 little longer, and the carpus about as long as iu the fourth ; the pro- 

 podus is fully half as long as the carpus, and more than twice as long 

 as in the fourth, and the dactylus is very slender and only about a fourth 

 as long as the propodus. 



The three anterior somites of the pleon are rounded above, but the 

 fourth, fifth, and sixth are compressed and sharply carinated dorsally, 

 and on the sixth somite the carina terminates iu li, small tooth at the 

 posterior margin. The telson is much longer than the sixth somite, 

 tapers regularly to a narrow tip, which, however, is not quite perfect in 

 either of the specimens, and is armed either side about a fourth of the 

 wa}^ from the tip to the base with a very long and slender spine.
