almost straight, the terminal spine which is not curved inward and which al most reaches 

 to the tip of the carpocerite, exceeds by one-third of its length the rounded tip of 

 the well developed scale, which is hardly shorter than the antennular peduncle. Upper 

 spine of basicerite very small, 0,13 mm. long. 



The length of the telson equals 2,44-times the width of the posterior margin, proportion 

 between the width at base and that of the posterior margin 1,9. The spinules of the upper 

 surface are small, those of the posterior pair are 0,2 mm. long; the anterior pair is situated 

 just midway between the base and the posterior margin, almost as far distant from the lateral 

 margins as from the median line of the telson, proportion between the distances of both pairs 

 from the posterior margin 1,8. Posterior margin a little prominent, outer angles accented, but 

 not spinous, very short ; internal longer spinules about halt as long as the width of the 

 posterior margin. 



The merus of the larger cheliped is just as long as that of the smaller and in both 

 meri the upper margin terminates in a small, acute tooth ; the former is 2,1-times, the latter 

 2,3-times as long as wide. Measurements of the larger chela : fingers 1; total length 4,6; 

 height 1,6; this chela is 2,82-times longer than high and 2,46-times as long as the smaller 

 chela. Anterior margin of the palm terminating in a small, acute spine, which is slightly 

 directed downward. 



The small chela has, as proportions: fingers i; total length 2,44; height 0,81, this chela 

 being just 3-times longer than high ; palm unarmed, fingers tapering. Merus of second legs 

 5-times as long as wide. The first segment of the carpus is 4,6-times as long as thick and as 

 long as the sum of the four following; it is slightly longer than the chela, the fingers of which 

 are one-sixth longer than the palm ; the third segment appears a little larger than the second 

 or the fourth. 



The third legs show the following relative dimensions: merus 2,23; carpus i; propodus 2,05. 

 The merus is unarmed, 3,66-times longer than wide and 1,1-times longer than the propodus; 

 propodus 6-times longer than wide, slightly narrowing distally and armed with 6 spinules, that 

 are 0,15 — 0,22 mm. long. Measured from the base of the anterior margin to the extremity of 

 the ventral hook, the dactylus proves to measure one-fourth of the propodus and to be 3-times 

 as long as wide near the articulation, being of a rather slender form; the ventral hook which 

 makes a very obtuse angle with the posterior margin of the dactylus, is one and a half as 

 long as broad near the articulation, its posterior margin is straight, the anterior arcuate. The 

 dorsal hook is twice as long, but just as broad at its base as the other, a little more 

 than 3-times as long as wide at its base and presents therefore a more slender shape ; notch 

 between the two hooks rather sharp, acute. These legs are slightly setose. 



Ova not numerous, rather large, 0,95 mm. long. Length 15 mm. 



Rem ark s. Syn. h ui 'ulensis Cout. and Syn. tumidomanus (Paulson) differ from this species 

 by the carpocerite and the antennular peduncle being of a more slender form: the carpo- 

 cerite is namely 4-times longer than wide, whereas the median antennular article is one and a 

 half as long as wide at the apex. Paulson's species cliffers moreover by the clearly spinous, 

 postero-lateral angles of the telson.
