124 CAEL BOVALLIUS, AMPHIPODA HYPERIIDEA. I. 2. HYPERIIDiE. 



Euiulopis Lovéni. 



The jirst and second pairs of ijerceopoda are similar to those pairs in the male. 



The third and fourth pairs are comparatively longer than in the male. The femur 

 is much longer than the feraur of the second pair, the base is very narrow, the lower 

 part very dilated, tlie joint being more than twice as broad below as at the base. The 

 genu is twice as long as broad. The tibia is a little longer than the genu, broader 

 below. The carpus is longer than the tibia, the hind margin is straight, not serrated. 

 The metacarpus is somevvhat shorter than the carpus, and much narrower, the hind 

 margin is straight, not serrated. The dactylus is curved, sraooth, equalling in length 

 a third of the metacarpus. Hair-covering as in the male. The glands are larger and 

 moi^e developed than in the male. 



The jiftli, sivth and seventh pairs are equal in length and similar in shape; they 

 are shorter than the third and fourth pairs. The femur is narrow at the base and broader 

 below, nearly twice as broad below as at the base. The genu and tibia are equal in 

 length. The carpus is longer than the tibia, but much shorter than the genu and tibia 

 together. The metacarpus is shorter than the carpus, dilated at the apex, the dactylus 

 irapinges against this dilated part of the joint, thus forraing a kind of grasping organ. 

 The dactylus is strongly curved, equalling in length a third of the metacarpus. Hair- 

 covering and glands as in the male. (Pl. VIII, fig. 13 and 14.) 



The pleon is scarcely longer than the last three perseonal segments together. The 

 first pleonal segment is as long as the last peraeonal one; it is a little longer than the 

 second segment. 



The pleopoda are like those in the male. 



The urus is a little shorter than the last t\vo pleonal segments together; it is some- 

 Avhat raore richly provided with hairs than is that in the male. The first segment is 

 a little longer than the last coalesced one. The last segment is almost twice as broad 

 as long, and of the same shape as in the male; the margins are fringed with short 

 hairs; the hind corners are broadly rounded. 



The uropoda (Pl. VIII, fig. 18). The Jirst jyair reach almost to the apex of the 

 last pair; the peduncle is somewhat broader than that in the male, fuUy three times as 

 long as broad; the margins are densely fringed with short, slender hairs. The rami as 

 in the male. The second pair do not reach fuUy to the middle of the outer ramus of 

 the last pair; the outer ramus is a little longer than the inner one, and about as long as 

 the peduncle; the margins are fringed with hairs as in the male. The peduncle of the 

 third pair is as broad as that of the first pair, densely fringed with short, slender hairs; 

 it is about a third longer than the last coalesced ural segment. The rami as in the male. 



The telson is about half as long as tlie peduncle of the last pair of uropoda, and 

 much broader than the same peduncle. The margins are entirely smooth.
