placed not far from the orbital margin, at one-seventh of the distance between the latter 

 and the posterior margin of the carapace. The upper border is armed with i 7 teeth, the three 

 first stand on the carapace ami, though slightly increasing in length, are distinctly smaller than 

 the 4"', which is placed above the orbital margin; the two first are articulated and thus probably 

 movable and this is perhaps also the case with the y^ ; the 4"' to 8"' tooth are of eciual size, 

 placed at equal distances except the 8'i> which is a little farther distant from the 7"' than the 

 preceding and this 8"> tooth is placed near the middle of the antennal scale, just in front of the 

 antennular peduncle. The fi)llowing teeth become gradually smaller, the distance between the 

 8''^ and the 9"^ is a little longer than that between the 8''^ and the 7''' and the distance between 

 the 9"> and the 10"' is still a little longer, the longest distance of all, but from here the distances 

 become gradually shorter; the foremost tooth stands as far from the tip of the rostrum as from 

 the penultimate. The lower margin bears 10 or perha[>s 11 teeth that are much smaller than 

 the 4^'' — 8'^ tooth of the upper margin; the i*^' stands between the 8"^ and 9"' of the upper 

 margin, the 2"^ nearly midway between the 9"' and the 10"', the distances between the following 

 gradually diminish in length. The rostrum is narrow and tapers slightly to the tip. The rostrum 

 of the female resembles, as far as it is preserved, that of the male, but the distance between 

 the 8"^ and the 9"' tooth of the upper margin is the longest of all. 



Antennal spine reaching to the cornea of the forwardly stretched eyestalks, branchiostegal 

 spine very small, much smaller than the other; carapace for the rest quite smooth. 



Abdomen nearly as long as carapace and rostrum combined, 3-times as long as the 

 carapace; all the abdominal terga, even the telson, are rounded, smooth; posterior margin of 

 3''^ tergum slightly conve.x, 6'^ somite (4,5 mm.) of the male almost twice as long as the s'"" 

 (2,5 mm.), telson (6,75 mm.) one and a half as long as 6''^ somite, a little shorter than the 

 inner, but much shorter than the outer uropod. 



Cornea as broad nearly as the eyestalk is long, ocellus cjuite distinct, circular, almost 

 independent, only anteriorly in contact with the cornea. Antennular peduncle short, reaching 

 only along the proximal third part of the antennal scale, 3"^'' joint a little longer than 2'"'; outer 

 flagellum as long as the body, rostrum included, widened proximal part measuring about '/; the 

 entire length of the flagellum ; inner flagellum about four-fifths of the other. .Stylocerite acute, 

 as long- as basal antennular article. 



Antennal scale (7,8 mm.) almost as long as the carapace and almost half as long as 

 the rostrum, in the male; it is narrow, 5-times as long as wide pro.ximally and narrows distinctly 

 anteriorly ; outer margin straight, terminal spine as long as the tip of the blade. Antennal 

 peduncle reaching to the distal extremity of the 2"'' joint of the antemuilar peduncle; flagellum 

 one and a half as long as the entire length from apex of rostrum to tip of telson. 



The external maxillipeds reach b\- the terminal joint and one-fifth of the penultimate 

 beyond the antennal scale; exopodite reaching almost to the middle of the antepenultimate joint. 



The peraeopods of the i*^' pair reach by their terminal joint (propodus) beyond the apex 

 of the rostrum, by their terminal joint and the distal third of the carpus beyond the external 

 maxillipeds; carpus twice as long as the terminal joint, which seems to bear a rudimentary 

 chela at the far end, long about 7:o o^ ^^e propodus.
