anterior third of that portion of the ridge traversing the finger is 
smooth. The under surface of the hand is smooth ; between the ridges 
there are scattered granules and small squamiform tubercles and some 
slight pubescence ; above the low, squamiform ridges either side of 
qhe palm and on its upper surface are a number of low, squamiform 
tubercles, more or less concealed by the thicker pubescence here, some 
are a little more conical than others and raised a little above the pubes- 
cence. The armature and ornamentation of the hands seems to be 
about as described for T. alcocki and, in general, not so very unlike 
the somewhat sketchy drawing of T. gardineri, although in the latter 
species, in place of the anterior conical tubercle on the outer margin 
of the upper surface of the palm, a spine as strong as the one behind 
it or opposed to it on the inner margin is shown. 
The movable finger, measured in a chord from tip to the middorsal 
point of the anterior border of the palm, exceeds, by about 2/7 of its 
length, the dorsal length of the palm measured back from the same 
point. The two chelae are about of the same size and have their fingers 
more or less of the same length : the right movable finger is very 
slightly the shorter. De Alan states that the fingers of T. alcocki are 
shorter than the palm ; in T. gardineri, as drawn, the movable fingers, 
at least, in the given dorsal view are longer than the upper margin 
of the palm, while in the figure presenting the outer face of the 
chela the finger is shorter than the dorsal length of the palm ; as this 
figure has been especially drawn to show the character of the chela, 
it undoubtedly portrays the correct relation of finger to palm. 
The carpus of the cheliped has a long, strong spine at the inner 
angle about twice the length of the palmar spine at the carpal articu- 
lation. There is a curved crenulate line back of this spine ; upper 
surface of carpus granulate or low tuberculate ; there are three spines 
toward the outer side of the carpus, the inner of these is the sharper, 
the next or middle one the larger, more produced, and subacute, the 
outer one is blunter, low, and more or less conical, a low ridge runs 
back from the first and third of these spines ; the ridge behind the 
first of the three spines is fine-crenulate, the other ridge behind the 
third spine is apparently finely and almost obscurely denticulate. 
The merus of the cheliped has three spines on the anterior border, 
the distalmost is the larger and placed at a lower level than the others, 
the proximal the smallest ; there are several small denticles or tubercu- 
liform teeth before the proximal spine, one between it and the second 
spine, and two or three, little larger than granules, bunched between 
the second and third : the anterodistal angle of the merus forms a
