two followino- taken together, 3 rd article one-third longer than 2 nd , 2 nd one-third longer than 

 thick. Stylocerite acuminate, a little shorter than the eyestalks. The eyepeduncles reach to the 

 distal sixth of basal article, their proximal half appears a little wider than the distal half and 

 the distance between the orbital margin and their distal extremity is almost 3-times as long 

 as their greatest width ; only a small spot of blackish pigment is visible on the outer side of 

 the cornea. The scaphocerite (Fig. 3 f) is 1,62 mm. long, about one-third of the length of the 

 carapace, it is nearly 3-times as long as wide and narrows rather little distally; the outer margin 

 is straight and the terminal spine, that projects beyond the rounded extremity of the blade, is 

 o, 106 mm. long. 



The external maxillipeds reach almost to the distal end of the scaphocerite, the length 

 of the terminal joint is in proportion to that of the penultimate as 5:3. 



The peraeopods of the two first pairs extend by somewhat more than the fingers beyond 

 the antennal scales. Merus of i st pair, like the preceding joints, unarmed, carpus short, about 

 one and a half as long as thick, with a small obtuse tooth at the far end of the lower margin. 

 Chela 2,34 mm. long, fingers shorter than palm, proportion like 5:8; width of palm about 

 one-third its length. The 2 nd legs (Fig. 3^ — i) are armed with a spine at the far end of the 

 basipodite, with a spine near the distal third of the merus and with another at the far end 

 of the lower margin of the carpus, the latter twice as long as wide distally. Chela 2,6 mm. 

 long, fingers also shorter than palm, but the proportion is like 6:8; palm 4 1 / 2 -times as long 

 as wide, its greatest width at the proximal third. 



The measurements of the legs of the 3 ld pair (Fig. 3/, 3 /F) are: ischium long 0,64 mm., 

 merus 1,62 mm., carpus 0,2 mm., propodus 0,78 mm., dactylus 0,38 mm. The exopodite extends 

 to the 2 nd third or fourth of the merus. The measurements of the 4 th pair (Fig. 3/, j«) are: 

 ischium 0,22 mm., merus 0,22 mm., carpus 0,1 mm., propodus 0,23 mm.; there is a seta long 

 0,14 mm. at the distal end of the propodus and another, 0,06 mm. long, a little behind it. The 

 exopodite projects still a little beyond the terminal joint of the endopodite. 



The 5 th pair (Fig. 3/2, 30), finally, presents the following measurements : ischium 0,38 mm., 

 merus 0,9 mm., carpus 0,22 mm., propodus 0,7 mm., dactylus 0,2 mm. long. The dactylus is 

 3-times as long as broad and bears 6 or 7 setae at the distal end and along the distal half 

 of the lower margin ; these setae are, like in Pas. Sivado and Pas. propiuqua, armed along 

 their distal half with triangular teeth and near the extremity with barbed hooks. The exopodite 

 reaches but a short way beyond the ischium. 



This species appears closely allied to that from Stat. 141, for which, when indeed new, 

 the name of kilarzila is proposed (p. 14), but is nevertheless no doubt different. In the species 

 from Stat. 148 the post-frontal tooth has a different form, the upper margin of the 6* abdominal 

 somite ends in a small acute tooth, while the posterior extremity of the telson is very slightly 

 convex. Merus and carpus of the i st pair of legs have a stouter shape, the merus is quite 

 unarmed, while the merus of the 2 nd pair is only armed with one spine. The species from 

 Stat. 148 is also related to Pas. Sivado (Risso), but I do not believe that it may be regarded 

 as a young of it.
