tnuch more spinulose than in the o ld er specimens already described, especially on 

 the regions posterior to the cervical groove. Just in front of this groove the gastric 

 region bears posteriorly several small spinules, that do no more occur in the older specimens 

 and two of which are placed in the meclian line ; the rest of the gastric region and the hepatic 

 area are like in the adult. Eighteen or 19 very small spinules stand on the cardiac region 

 betvveen the submedian doublé row of larger spines, traces of these 18 or 19 spinules are still 

 visible in the male from Sinabang-Bay, but they are fully wanting in the old male from Ternate, 

 in which even the 3 larger spines on either side of the middle are much worn off, especially 

 the 2 posterior pairs. The pale-coloured, longitudinal band that extends from the base of the 

 antennal peduncle to the postero-lateral angle of the carapace, bears 16 or 17 generally small 

 spinules, of which in the male from Sinabang-Bay only traces are visible, while this band is 

 almost fully smooth in the male from Ternate. The rest of the branchial region and the 

 intestinal region appear also much more spinulose. The 2 nd abdominal tergum bears, immediately 

 in front of the posterior blue band, a shallow, trans verse groove, which is everywhere 

 covered with short hairs ; this furrow is interrupted in the middle and each half narrows 

 somewhat laterally. A faint tracé of a similar groove, already glabrous however, exists on the 

 3 ld tergum, but on the following somite it has already fully disappeared. 



The antennular tergum carries 4 slender, acuminate spines, that stand in a quadrangle, 

 those of the posterior pair are little shorter than the anterior. The internal antennae are 220 

 mm. long, the peduncle that measures 62 mm., is little longer than the carapace; the shorter 

 flagellum measures 100 mm. The peduncle extends by its terminal joint beyond the distal 

 end of that of the outer antennae. 



The small flagellum of the exopodite of the 2 nd pair of maxillipeds is 2 l / i mm. long 

 and almost 3-times as long as broad, not articulate, fringed with hair and it reaches barely 

 beyond the distal end of the merus-joint. 



Like in the two preceding specimens the external angle of the upper surface of the 

 coxa is armed, in the legs of the 5 th pair, with a short acute spin e, instead of it 011e 

 observes in the male of Panul. ornatus (Fabr.) from Stat. 71 an obtuse prominence. 



The larger female from Stat. 301 is 120 mm. long, the colour has been apparently 

 typical, but has changed and faded away still more than in the preceding specimen. The 

 carapace appears as much spinose as in the female from Stat. 131. The 2 nd and the 3" 1 

 abdominal terga bear each a shallow, transver se groove coverecl with hair 

 and interrupted in the middle; the interruption is twice as broad on the 3 ld somite as 

 on the 2 nd and the groove of the 3 rd somite is only half as long as that of the 2 nd . The 

 flagellum of the exopodite of the 2 nd maxillipeds is not yet one millimeter long and barely 

 reaches the distal end of the merus-joint. Spine on the coxa of the 5 th legs well developed, 

 the legs of the 3 rd pair are the longest. The abdominal appendages agree with those of the 

 preceding specimens. The exopoclites are beautifully wine-red coloured on their distal half and 

 are traversed in the middle by 3 yellow lines, of which the middle one extends to the end of 

 the plate, the two others are shorter. 



The other female from this Station is 65 mm. long, the necks on the upper surface of
