maxillipeds (Fig. 7/) is 6-times as long as wide, its inner margin is thickly beset with setae, 

 while short setae are implanted on the outer; there are two longer setae at the distal end that 

 measure about one-third the length of the joint. 



Both in the adult male and the ova-bearing female the lower margin of the palm of the 

 i^' pair of legs (Fig. 7;') is armed with 4, rarely 3, spines, while the upper is unarmed; in the adult 

 male the palm is 1,4 mm. long and 0,56 mm. broad, in the ova-bearing female 1,3 mm. long 

 and 0,54 mm. broad, the palm being almost 3-times as long as broad, as I already indicated 

 in my work of 1902. In both sexes the outer margin of the dactylus bears 4 or 5 spines, like 

 in Lept. serratoi'di/a. Both in the male and in the female the carpus is i mm. long and 

 0,56 mm. thick distally, nearly twice as long as thick; it is armed on the middle of the lower 

 margin with 2 spines and at the distal end with 2 or 3, one of which is a little larger than the 

 two preceding, while the two other spines are successively smaller. Merus, both in the male 

 and in the female, 2Yo-times as long as the carpus and 4-times as long as wide; its lower 

 margin is armed in the male with 4, in the female with 5 spines, both the upper and the lower 

 margin are setiferous and there are 5 or 6 setae at the far end of the upper. Ischium almost 

 just as long as the merus, also about 4-times as long as wide, slightly narrowing towards the 

 proximal extremity, setiferous, but not armed with spines, except one at the distal end of the 

 upper margin. Basipodite setiferous along the lower margin, with a single spine at the distal 

 extremity. Exopodite just reaching beyond the far end of the merus. 



The legs of the 2°'' pair (Fig. "jt) show the same form and relative measurements as those 

 of the 1^', but they are a little longer and a lit tie more spiniferous. Dactylus with 5 or 6 spines. 

 The carpus is armed with 4 or 5 spines on the lower side of the distal margin in both sexes and 

 with 3 or 4 spines on the lower margin. The lower margin of the merus does not carry 4 or 

 5 spines, but in the male 7 and in the female even 9 and one observes moreover on the distal 

 margin of this joint in the male one, in the female two small spines, and behind them on the 

 outer surface 2 small spinules. There are 3 spines near the lower margin of the ischium and 

 one observes on the basipodite, besides a spine at the distal end, still two on the proximal 

 half of the lower margin. The exopodite, finally, is a little shorter than the ischium. 



The peraeopods of the 3"^ pair of the adult male agree with my description of 1902, 

 except in the following. The dactylus is not precisely as long as the propodus, but one-sixth 

 longer and 1 2-times as long as wide in the mjddle. The propodus is armed along its lower 

 margin with 5 slender spiniform setae that sljghtly increase in length distally and with 2 at the 

 far end, of which the longer measures three-fifths the length of the propodus. The ischium that 

 slightly widens distally. is just as long as the merus, 4-times as long as wide at the far end 

 and armed along the lower border with 4 short spines, while long setae stand on the upper. 

 On the lower border of the basipodite 3 slender spines are implanted and the exopodite is a 

 little shorter than the ischium. The 3''' legs of the female (Fig. jii) agree with those of the 

 male, but the propodus is almost twice as long as the carpus and furnished with 6 or 7 spiniform 

 setae along the lower margin, besides the two at the distal extremity; the dactylus is sometimes 

 nearly just as long as the propodus, but is also 1 2-times as long as wide in the middle. 

 Exopodite just as long as the ischium.
