the front margin is smooth. The tibia is shorter than half the femur, the front margin 

 smooth, the hinder margin armed with eight teeth. The carpus is longer than the tibia, 

 fully half as long as the femur, the front margin and the sides provided with some long 

 hairs, especially at the lower apex, the hind margin armed with nine larger and some few 

 smaller teeth. The metacarpus is somewhat shorter and considerably narrower than the carpus, 

 feebly bent, the front margin is smooth, the hind margin armed with about twenty-four 

 smaller teeth. The dactyl us is long, slender, almost straight, equalling more than a fifth of 

 the length of the metacarpus. The length of the leg is 21 mm. (spec. B.), or 22 mm. (spec. A.). 



The fourth pair (PI. Ill, fig. 10) equal about two thirds of the length of the fifth 

 pair, and are similar in shape to the third pair. The femur is almost as long as the 

 three following joints together, the front and inner margins are smooth, the hind margin 

 is armed with thirteen unequal teeth. The short genu has two teeth on the hinder margin. 

 The tibia is half as long as the femur, the hind margin with eleven teeth. The carpus 

 is a, little longer than the tibia, the hind margin with fourteen teeth; the joint is richly 

 provided with hairs at the lower apex. The metacarpus is narrow, feebly bent, some- 

 what longer than the carpus, the hind margin with about twenty-four small teeth; on the 

 sides of the joint there are four or five transversal rows of short hairs. The dactylus 

 as in the preceding pair. The length of the leg is 31 mm. (spec. B.), or 31,5 mm. (spec. A). 



The fifth pair (PI. Ill, fig. 11) are much longer than the pera^on and pleon together 

 (3: 2), and nearly -thrice as long the seventh pair. The femur is linear, narrow, almost 

 ten times as long as broad, and only a little broader than the tibia, serrated along the 

 front, hind, and inner margins, the number of teeth being eleven to fourteen along each 

 margin; the lower anterior corner is a little produced. The genu is short, with two teeth 

 on the front margin, and none on the hinder and inner margins. The tibia has fourteen 

 teeth along the front margin, five to six very small ones on the inner margin, and two 

 or three low teeth on the hind margin. The carpus is much longer than the tibia, and 

 only a little shorter than the femur, with twenty unequal teeth along the front margin, 

 the hinder and inner margins being almost smooth. The metacarpus is somewhat shorter 

 than the carpus, not distinctly prismatic; the front margin is provided with about fifty very 

 low and small teeth; the hinder side is totally smooth. The dactylus is feebly bent, 

 equalling about a tenth of the length of the metacarpus. The length of the whole leg- 

 is 46 mm. (spec. B.), or 50 mm. (spec. A.). 



The sixth pair (PI. Ill, fig. 12) are fully twice as long as the seventh pair. The 

 femur is a little shorter than the femur of the fifth pair, and less produced at the lower 

 anterior corner; it is twice as long as the femur of the seventh pair; the front margin is 

 provided with fourteen teeth, the ten uppermost being very small, the lowest, the produced 

 anterior corner, the largest; the hinder margin carries twenty-one strong teeth; the inner 

 margin is indistinctly denticulated. The genu has two strong teeth on the front margin, 

 none on the hinder and inner margins. The tibia is a little more than half as long as 

 the femur, with fifteen very unequal teeth along the front margin, and twelve along the 

 hinder margin; on the inner there are some few low teeth. The carpus is longer than 

 the tibia, armed along the front margin with twenty-three unequal teeth, some of them 

 very small; the hinder and inner margins are indistinctly denticulated. The metacarpus
