1905.] FROM CHRISTMAS ISLAND. 547 



The I'iglit leg (fig. 9) lesembles the one described (confer the 

 measurements), but the palm is a liitle less broad than the distal 

 end of the carpus, and the crowded spinules on the inner border 

 of the palm are decidedly larger than those on the outer border. 

 The toothing of the fingers is also different, the teeth being much 

 smaller. The fixed finger carries a minute, conical tooth at one- 

 third of its length from the articulation, and a smaller one behind 

 it ; at two-fifths of its length from the articulation the dactjdus 

 carries a similar, small, acute tooth, and between it and the arti- 

 culation four much smaller teeth, also sharp. The palm of both 

 legs is somewhat marbled by darker flecks ; the fingers ai'e bluish 

 on their lower side with yellow tips, whereas their pale yellow 

 upper surface is marked with three or four blue bands. 



The three following legs are also of a stouter shape than in the 

 typical specimens of Pal. lar. The 3rd pair reach to the end of 

 the antennal scales, the 4th are a little shorter, and the 5th pair 

 reach to the distal third pait of the scales. The breadth of the 

 meropodites of the 3rd pair (PI. XVllI. fig. 11) is little more 

 than \ of their length, and that of the propodites little more 

 than 1 of the length of these joints. The basal joints and the 

 meropodites are smooth above, but their lower surface is beset 

 with small spinules, a few of which occur also on their outer 

 surface. The carpopodites are on all sides covered with similar 

 spinules, and the propodites are still more spinidose ; the spinules 

 show here a temiency to be arranged in longitudinal rows. The 

 lower border of the propodites carries a row of larger spines, 9 or 

 10 on the propodites of the 3r;l legs, which ai'e 0-36 -0"4 mm. long ; 

 on the piopodites of the 5th pair these larger spines of the lower 

 border are 14 or 15 in number and become distally a little longer, 

 so that the last one near the articidation of the dactylus is 

 0"55 mm. long. The dactylopodites of the 3rd pair (fig. 11) 

 measure somewhat n. ore than one third, the shorter dactyli of the 

 5th one-fourth of their propodites. The ambulatory legs ai-e a 

 little haiiy, especially the carpo- and propodites ; the hairs, how- 

 ever, are short and fine. A tuft of hairs occurs at the distal end 

 of the upper border of the pi-opodites, and those of the 5th pair 

 carry, moreover, a brush of haii'S at the far end of the lower 

 border. 



The rostrum of the female (PI. XVIII. fig. 12) is slightly inclined 

 downward and reaches to the distal end of the peduncles of the 

 internal antennre. The upper border carries 9 teeth, the 3rd of 

 which is situated not before, but just above the frontal margin, 

 two standing also on the carapace ; the teeth, which reach to the 

 tip, are a little unequal, the 2nd and the 6th being longer than 

 the rest, and the foremost tooth is smaller than the preceding. 

 The lower edge carries 3 smaller teeth, the tip of the 3rd tooth, 

 which is situated just below the middle of the penultimate tooth 

 of the upper border, is once and a lialf as far distant from the 

 extremity of the rostrum as from the tip of the 2nd tooth of the 

 lower border.
