The toothing of the fingers is also different, the teeth being much smaller. The fixed finger carries a minute, conical tooth at one-tliird of its length from the articulation, and a smaller one behind it ; at two-fifths of its length from the articulation the dactylus carries a similar, small, acute tooth, and between it and the articulation four much smaller teeth, also sharp. The palm of both legs is somewhat marbled by darker flecks; the fingers are 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 5tli pair reach to the distal third part of the scales. The breadth of the meropodites of the 3rd pair (PI. XVIII. fig. 11) is little more than |r of their length, and that of the propodites little more than i 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 spinulose; the spinules show here a tendency 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 3rd legs, which are 0'36-0‘4 mm. long ; on the propodites 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 articulation 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 5tli one-fourth of their propodites. The ambulatory legs are a little hairy, especially the carpo- and propodites; the hairs, however, are short and fine. A tuft of hairs occurs at the distal end of the upper border of the propodites, and those of the 5th pair carry, moreover, a brush of hairs 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 antennfe. 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 6tli 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 half as far distant from the extremity of the rostrum as from the tip of the 2nd tooth of the lower border. |
