a little in size distally, and are situated at unequal distances to near the tip. In the adult species 

 the lower margin is armed with 20 — 25 teeth, of which the first is situated near the distal 

 third of the antennal scale; these teeth are considerably larger than those of the upper 

 margin, especially the 10 or 12 proximal ones that are approximate, while the follovving that 

 reach to the tip, are placed at small though subequal distances from one another. 



Branchiocardiac groove distinct, not reaching to the posterior margin of the carapace 

 and running obliquely. 



Examined under a strong magnifying glass, both carapace and abdomen appear very 

 finely granular. Abdomen, telson included, 4-times as long as carapace. Third abdominal tergum 

 moderately prominent posteriorly. In the adult female the 6 th somite (7,75 mm.) is not yet 

 3-times as long as the 5 th (3 mm.), but in the male, in which these numbers are 6,75 mm. 

 and 2,25 mm., it is the case; in the male the 6 th somite is 2,5 mm. high proximally, in the 

 female 2,75 mm., the somite appearing in both specimens not yet 3-times as long as high. 

 Telson a little shorter than 6 th somite, slightly longer than the endopodite, but distinctly shorter 

 than the exopodite of the caudal fan; there are 4 pairs of dorsolateral spinules, besides those 

 at the tip, the i st or anterior pair, implanted just before the middle, is as far distant from the 

 2 nd as the 2 nd from the 4" 1 or posterior pair. 



Spine at the outer angle of the 2 nd joint of antennal peduncle rather long; antennal scale 

 long and narrow, tapering, as long as the carapace, measured dorsally, outer margin straight, 

 terminal spine reaching far beyond the truncate tip of the lamella. 



Peraeopods according with the original description. 



Parap. Zur Strasseni Balss is easily distinguished from the other species of the genus 

 by the shape and armature of the rostrum.

Stat. 251. Dec. 8. 5°28'.4S., i32°o'.2E. West of Kei-islands. 204 m. Bottom hard coral sand. 

 2 adult females, one of which with eggs, and 1 young specimen. 



The larger female which is not laden with eggs, is 126 mm. long from apex of rostrum 

 to tip of telson, the other measures 122 mm. and the young specimen 79 mm.; the rostrum 

 of the ova-bearing female, measured from the orbital margin to the apex, is 33 mm. long, the 

 carapace 20,75 mm., the abdomen 68,25 mm., in the two other specimens these numbers are, 

 in the same succession, 36 mm., 21 mm., 69 mm. and 23,75 mm., 13,25 mm., 42 mm. In 

 the two full-grown females the rostrum proves to be one and two-thirds as long as the carapace, 

 in the young specimen almost twice as long, and in the young specimens, collected by the
