tolerably strong, acute tooth at the far end of posterior margin ; 

 propodite twice as long as the carpus, 8,4-times longer than wide 

 with 15 small spiuules; dactylus oue sixth of the propodite, the 

 ventral hook almost as thick as the other and perpendicular to 

 the inferior margin. Leugth of this male 21 m.m. 



In the male long 15 m.m. from Station 91 the larger chela 

 resembles that of Syn, Stimpsonii and the 3rd — 5th legs are of 

 a somewhat stouter shape, but the ventral hook of the dactyli is 

 also perpendicular to the inferior margin. 



In the young specimen long 11 m.m. from Station 305 the 

 dactyli are as in Sijn. Stimpsonii., but the scaphocerite is as in 

 the male from Station 213, as also the arrangement of the spinules 

 on the telson.

Station 65a. Very near Station 65 (Lat. 7° O' S., long. 120° 



34'. 5 E). Depth changed rapidly during haul, diminishing 



from 400 M. to 120 M. 



Station 260. Lat. 5° 36'. 5 S., long. 132° 55'. 2 E. — 2,8 miles 



N., 63° W. from the North point of Nuhu Jaan, Kei-islands.

Station 289. Lat. 9° O'. 3 S., long. 126° 24'. 5 E. Depth 112 M. 



A new species of small size of the Comatularum group. Frontal 

 regiou as in the other species of this group, rostrum hardly longer 

 than broad at its base, reaching to the middle or to the distal 

 third or fourth part of 2nd antennular article, supraorbital spines 

 short, one fourth of the rostrum. Telson 4 — 4,5-times longer than 

 the width of posterior margin, greatest width 8-times the width 

 of posterior margin ; anterior pair of spinules twice as far distant 

 from the posterior margin as from the base, posterior pair midway 

 between the posterior margin and the anterior pair or somewhat 

 nearer to the latter. 



Antennal and antennular peduucles as in Syn, Stimpsonii (Archiv 

 f. Naturg. 53, 1888, Taf. XXII, Fig. 3), but the stylocerite reaches 

 only to the middle of visible part of Ist antennular article and the
