low teeth, each tipped with a similar hair. The dactylus is curved, shorter than the 

 breadth of the metacarpus, and scarcely equalling a fifth of its length. Glands as in the 

 preceding pairs. 



The fifth pair are longer than the fourth, but shorter than the third pair. The 

 femur is elongate, a little more than three times as long as broad, and considerably shorter 

 than the three following joints together; the front margin carries five to six long hairs, 

 the lower corner is feebly produced, the hind margin is smooth. The genu is as long 

 as broad, the front margin with minute hairs, the hind smooth. The tibia is almost as 

 broad as the femur, and about half as long; the front margin is indistinctly serrated, the 

 teeth tipped with short hairs; the hind margin is smooth, the lower corner strongly pro- 

 duced, tipped with two short hairs. The carpus is only a little shorter than the femur, 

 and more than three times as long as broad; both margins are serrated, the teeth on 

 the front margin are tipped with short hairs. The metacarpus is- much shorter and narrower 

 than the carpus, feebly curved, the front margin is finely serrated, the hind smooth. The 

 dactylus is small, curved, scarcely as long as the breadth of the metacarpus, and equall- 

 ing a fifth of its length. Strongly developed glands, especially in the femur and 

 carpus. 



The sixth pair are shorter but more slender than the fifth pair. The femur is 

 not three times as long as broad, the hind margin curved, the front margin almost 

 straight or a little excavated, both are smooth. The genu is as long as broad, smooth. The 

 tibia is longer than half the femur, and narrower, the margins are smooth. The carpus is 

 a little shorter than the femur, narrower than the tibia; the margins are smooth. The meta- 

 carpus is shorter than the carpus, but longer than half the femur, almost linear, six times 

 as long as broad, with some short hairs around the apex. The dactylus is slender, al- 

 most straight, equalling a sixth of the length of the metacarpus. Glands as in the pre- 

 ceding pair. 



The seventh pair (PI. V, fig. 16 and 17) are as long as the first pair. The femur 

 is linear, about thrice as long as broad, the margins are smooth. The genu is as long as 

 broad, smooth. The tibia is scarcely half as long as the femur, broader below, smooth. 

 The carpus is very thick and broad, filled with glandular matter; it is only a little 

 shorter than the femur, the margins are smooth. The metacarpus is about half as long as 

 the carpus, and much narrower, linear, the apex broad, dilating behind the base of the 

 dactylus, and fringed with hairs; it is possible that there is an outlet for the glands at 

 this lower hinder corner of the metacarpus. The dactylus is very short, feebly curved 

 at apex. All the joints are provided with glands. 



The pleon is normal, not inflated, rather more slender than in the most of the true 

 Hyperidae. The first segment is the longest, the third the shortest. The hinder corners of 

 the lateral parts of the segments are rounded. The pleon and urus together are longer 

 than a third of the diameter of the globe. 



The pleopoda (PI. V, fig. 19, 20 and 21). The peduncles are longer than the rami, 

 obtusely ovate. At the inner lower front corner of each peduncle there are two short, 

 stout spines, fixed on a common rounded boutton-like desk; these spines are the
