68 CARL BOVALLIUS, AMPHIPODA HYPERIIDEA. I. 2. MIMONECTIDtE. 



The ovitectrices (Pl. VI, fig. 5) are corapai-atively much longer and narrower than 

 in Mimonectes Lovéni, and much naiTower than in M. Steenstrupi ; that of the second pair 

 is seven times as long as broad, densely fringed with long, simple hairs; it is more than 

 half as long as the second pair of pera^opoda; those of the third to sixth pairs are only 

 a littlc shorter than the corresponding legs. 



The Jirst pair of j^eneojjoda (Pl. VI, lig. 4) are only a little shorter than the second 

 pair. The fem ur is elongate, almost linear, fully three times as long as broad, smooth; 

 on the inner side of the front margin is a long narrow groove for the reception of the 

 rest of the leg, when folded up. The ge nu is more short than broad, with some hairs at 

 the lower, hinder corner. The hind margin of the tibia is longer than the genu, indi- 

 stinctly seri-ated, and fringed with long hairs, especially at the lower, produced corner. 

 The carpus is half as long as the femur, very broad, much broader than the metacarpus, 

 the loAver, hinder corner is rectangular, armed with strong bristles, the hind margin shows 

 six large teeth, each tipped Avith a bristle, the front margin is almost straight, with three 

 long hairs. The metacarpus is almost as long as the carpus, the hind margin has 

 between the middle and the apex a low prominence, armed with spines and strong bristles; 

 the front margin is nearly straight, fringed with slender hairs. The dactylus is straight, 

 sharp-pointed, fully equalling a third of the length of the metacarpus; on the hinder side 

 it has at the base a large opening for the outlet of the secretion from the glands, which 

 are to be seen within all the joints. 



The second pair (Pl. VI, fig. b and 6). The femur is about as broad as in the 

 first pair, elongate, thrice as long as broad, with some hairs on the feebly curved hind 

 margin; the front margin is smooth, and provided with such a narrow groove as mentioned 

 in the first pair. The genu is more broad than long, with some short hairs on the under 

 margin. The tibia is longer than the genu, provided with short bristles on the feebly 

 produced lower, hinder corner. The carpus is very shoi't, scarcely equalling a fourth of 

 the length of the femur, it is not broader than the metacarpus, fringed with long bristles 

 on the under margin, the front and hind margins are smooth. The metacarpus is twice 

 as long as the carpus, the front margin smooth; the spinulous prominence on the hind 

 margin is more strongl}' developed than in the first pair. The dactylus is longer than 

 a third of the metacarpus, feebly bent at apex. Glands as in the preceding pair. 



The third and fourth pairs are equal in length, more slender than in both the 

 other species, the third pair equal about a sixth of the length of the diameter of the globe. 



The /?/i(A pair (Pl. VI, fig. 7) are the longest of all, slender. The femur is almost 

 four times as long as broad ; the front margin is feebly curved, with six long teeth, each 

 tipped with a short spine, the lower corner is sharp-pointed, carrying a similar spine ; the 

 hind margin is straight, with a long, narrow groove for the reception of the three next 

 joints of the leg, when folded up. The genu is fully as long as broad, smooth. The 

 tibia is shorter than half the femur, broader than the carpus; the front margin is fi'inged 

 with some very short spines ; the hind margin is feeblj' curved, the lower corner is a little 

 produced, sharp-pointed. The carpus is more than half as long as the femur, linear; the 

 front margin with eight low teeth tipped with minute spines; along the outer side there is a 

 row of spines. The metacarpus is shorter and narrower than the carpus, tapering; the
