74 THE VOYAGE OF H.M.S. CHALLENGER. 



The palp of both maxillipedes was entirely wanting in the specimen ; bul I have 



little doubt that fig. 2, copied from a drawing left by the late Dr. v. Willcnioes-Sulnn, 

 represents the maxillipede palp. 1 



The lamina of the maxillipede is somewhat curved at its tip, it is a thin delicate 

 plate. The stipes of the maxillipede has the distal joint furnished with a single row 

 of the peculiar sense organs found in this situation in most [sopoda al«>ng the 

 inner margin, these commence at the base of the joint and are continued up nearly to 

 its. summit; the distal extremity of the joint is truncate and bears a row of long 

 yellow spines like those of the maxUla, and interspersed among them a number of fine 

 hairs; a projecting portion of the joint, at the inner side, bears three enormously thick 

 knife-shaped spines, behind which is a tuft of slender hairs. 



Of the thoracic appendages only stumps are left as indicated in the figure (fig. 1); 

 the first four appendages gradually increase in size, the first being the most slender and 

 the fourth the stoutest. The fifth and sixth pairs of limbs have their basal joints of 

 about equal thickness to those of the fourth pair. The last pair of ambulatory limbs are 

 again more slender. 



Reference has already been made to the mode of attachment of these limits. 



The first pair of abdominal limbs are fused to form a tongue-shaped appendage, 

 which covers over the gills. A central ridge marks the union of the two halves as 

 well as the free extremity, which is bifid ; the two ends being curved away from each. 



The uropoda are not present in the specimen and I am inclined to fancy that they 

 may be altogether aborted in this species ; there was, at any rate, no trace of any place 

 of articulation.

The present species is not unlike Eurycope pelludda ; it has the same remarkable 

 transparency of body, but its chitinous integument is even less resistent than that of 

 the species last described. The specimen has consequently collapsed altogether, and the 

 figure which illustrates it is copied from a drawing by v. Willemoes-Suhm, which 

 doubtless represents the Crustacean more accurately than any sketch which could now 

 be made. Although the general outline ami shape of the individual cannot be properly 

 made out from the alcohol specimen, the appendages are better preserved than those of 

 Eurycope pelludda; in addition to the mouth and abdominal ap] s, the firsl
