R. DOUGLAS LAURIE—BRACHYURA. 453 
fairly long scattered setse, which do not, however, hide the armature beneath 
them. ‘The lower and posterior surfaces of the meropodite are granular, the 
anterior surface is smooth, the upper border bears a row of about seven long 
sharp teeth. The carpopodite has a double row of teeth on its dorsal border 
and a third row on the upper part of the posterior surface. The anterior and 
posterior rows of teeth are continued along the propodite, the posterior one 
being brought up to a higher level; the middle row is continued halfway 
along the propodite in the 1st, not so far in the 2nd,a single tooth in the 3rd, 
and not at all in the 4th walking-leg. The teeth are continued along the 
upper edge of the dactylopodite. There are a few small teeth distally on the 
lower border of the meropodite, a single distally directed sharp tooth on 
the distal end of the lower border of the propodite, and two rows of small 
teeth on the lower border of the dactylopodite, terminating in a pair of larger 
ones at the base of the brown claw. 
The abdominal terga are in both sexes smooth for the most part, with a few 
sete along the lines of articulation of the segments. The margin of the 
abdomen is fringed inconspicuously with short sete in the ¢, and in the 9 
with conspicuous long sete. The abdomen is 7-segmented in the ? and 
o-segmented in the 3. 
Colours in spirit whitish, with the anterior portion of the carapace and the 
meri and carpi of the chelipeds a faint orange-red, the same colour much 
deeper on the hands and also on the exposed surface of the external maxilli- 
pedes ; fingers chocolate-brown with white tips, the colour of the fixed 
finger extends a short but quite evident distance along the lower border and 
both surfaces of the hands. 
Remarks. The smaller specimens differ from the larger ones as follows :— 
(1) The armature is sharper: thus the granulation of the carapace and 
chelipeds is crisp, and the tubercles of the chelipeds are dentiform, the two 
at the inner angle of the wrist in particular are stout curved spines. 
(2) The areolee are less distinct. 
(3) The antero-lateral lobes tend to be spiniform and procurved (see 
Table, p. 454). 
(4) In the young ¢ the chelee show less differentiation from each other 
and from the ? type, and in the young ? the abdomen is fringed with short 
inconspicuous set only. 
Apart from the above changes, associated with growth, there appears to be 
considerable variation in the distinctness of the granulation and areolation of 
the carapace, this being most pronounced in specimens 206 and 212. 
The following table illustrates certain growth-changes, together with some 
characters of the genus Chlorodopsis, and also shows that either cheliped may 
be the larger in the present species :—
