CUMACEA FROM THE COPENHAGEN MUSEUM. 369 



at the tip, which beiirs two extremely miuute setiforni points. From the side it is 

 seen to be tubular anteriorly, but cut away below from about the middle of its length 

 to receive the obliquely placed anal valves. The apex of the telson does not project 

 beyond the upper ends of the valves. 



The antennules have the first segment of the peduncle longer tluui the other two 

 together, and the second about half the length of the third ; the outer fiagellum is 

 composed of two segments, of which the first is the longer; the inner fiagellum 

 is composed of three segments and is about equal in length to the first segment of 

 the outer. 



The autenntc arc short, of three segments, with possibly a very minute terminal 

 segment; each segment carries a plumose seta. 



The mandibles are of the usual shape, witli an elongated body and a row of 

 twelve spines. 



The other mouth-parts are of normal type. The maxillular palp is short and 

 carries two setae. 



The first maxilliped lias three very long setae springing from the last three segments. 

 The branchial apparatus is quite devoid of lobules, witli the possible exception of a 

 vestigial one near the proximal end. 



The second maxilliped has a very long seta springing from the penultimate segment ; 

 the basal plate has eight setse. 



The third maxilliped has no exopod ; the basis is slightly expanded but not 

 produced distally, where it bears a series of long plumose setae ; the distal segments 

 are rather slender, the propodus a little longer than either the carpus or the dactylus. 



The first legs are stout and do not extend much in front of the pseudorostrum ; 

 the basis is about three-fourths as long as the distal segments together; the carpus is 

 nearly twice as long as the two preceding segments together and has the inner edge 

 irregularly tuberculate ; the propodus is less than half as long as the carpus; the 

 distal half of its inner edge is oblique and bears a series of ten very long smooth setae, 

 each slightly expanded at the base and four times as long as the segment from which 

 they spring; the dactylus is little more than half as long and one-fourth as broad as 

 the propodus, and bears one very long and some short setae at the tip. 



The second legs have the basis little more than twice as long as broad and as long 

 as the remaining segments together ; the distal segments become successively more 

 slender; the dactylus is about as long as the propodus; the ischium is distinct, but 

 very short. 



The remaining legs are stout; the merus is slightly inflated, twice to three times as 

 long as the carpus ; the dactylus is slender, as long as the propodus, and its terminal 

 spine is straight and very short. 



The uropods have the peduncle a little shorter than tlie last somite and about
