than in the specimen from Stat. 105, the merus is quite unarmed and the chela more swollen, 

 of the 2 nd pair the merus bears but one single spinule on its posterior border.

Stat. 141. August 5. i°o'.4S., 127° 25'. 3 E. Betvveen Batjan and the Obi Islands. From 1500 m. 

 to surface. 



I do not prosper in determining with certainty this specimen, which probably belongs to 

 a new species; on account of its small size it seems to be young. The proportion between the 

 leno-th of carapace and abdomen is the same as in Pas. kaiwiensis Rathb., the former being 

 ij'l mm. long, measured in the middle line, the latter 23^ mm., the entire length being 31 or 

 32 mm. Front broadly triangular, obtuse, resembling that of Pas. kahviensis (Fig. 6) and as little 

 prominent. There is no sinus between the rounded outer orbital angle and the likewise rounded 

 antennular prominence, while the two following sinuses are more shallow than in Pas. kahviensis, 

 so that the antero-lateral margin of the carapace shows a different appearance from that species. 

 The dorsal tooth is rather small, triangular, acute, though not spiniform as in Pas. kaiwiensis, 

 its upper margin is nearly straight and it does not reach to the level of the frontal prominence. 

 For the rest the carapace resembles that of Pas. kahviensis, being 3 3 / 4 mm. high at the level 

 of the branchial regions. 



The abdomen (Fig. 5 a) also agrees with that of Pas. kaiwiensis, except in the following. 

 The 6 th segment, 5,5 mm. long and 2,5 mm. broad, is al most twice as long as the 5 th 

 (2,9 mm.) and a little more than twice as long as broad, while in Pas. kaiwiensis 

 the proportion is like 5:3: the 6 th segment appears therefore narrower and the lower 

 margin ends posteriorly in a small spine. The telson is 3,8 mm. long, nearly two-thirds the 

 length of the 6 lh segment; the tip, 0,4 mm. broad, is hardly emarginate, still less than that 

 of Pas. kahviensis, and it is half as broad as the base of the telson, the upper surface of which 

 resembles that of Pas: kaiwiensis . Eyestalks like in this species, but the corneae pale brown. 



The antennular peduncle reaches three-fourths of the way along the antennal scale, 3 rd 

 joint one and a half as long as 2 nd ; stylocerite as in Pas. kahviensis. Antennal peduncle 

 reaching almost to the distal end of 2 nd antennular article, spine on basal joint like in Pas. 

 kahviensis. Scaphocerite (Fig. 5Ó) 3,6 mm. long, not yet half as long as the carapace, 

 comparatively wider than that of Pas. kahviensis, being 1,1 mm. broad, about 3-timës 

 as long as wide; the scaphocerite is also less narrowed distall y than in Pas. kahviensis 

 and the terminal spine is shorter, reaching hardly beyond the blade. 



The external maxillipeds extend to the distal extremity of the scaphocerite. The peraeopods 

 of the i st pair (Fig. 5c, $d) reach by the fingers and one-third of the palm, those of the 2 nd by 

 the fingers and almost half the palm beyond the antennal scale. Merus of the i st pair 3,45 mm. 

 long, 11-times as long as wide in the middle, where a small spinule is implanted; merus hardly 

 thickened at the distal end. Carpus one-fourth of the merus, twice as long as thick distally. 

 Chela 4,26 mm. long, nearly one-fourth longer than the merus, palm comparatively longer than 

 in Pas. kahviensis, one and a half as long as the fingers and 4-times as long as
