THE KILIMA-NJAP 0 EXPEDITION.\ 
equal portions by the zigzag cervical suture, which extends transversely 
across the carapace to the postero-lateral margins ; behind this a second 
transverse depression (not a suture) crosses the carapace behind the 
cardiac region. The postfrontal crest extends to the antero-lateral 
margins of the carapace, and is interrupted only by the meso-gastric 
suture, which bifurcates posteriorly (as usual in the genus); this crest 
is granulated near to the antero-lateral margins, which are defined by 
a distinctly granulated line; the lateral epibranchial teeth are not 
developed. On the hepatic and branchial regions are several faintly 
indicated lines, which extend inward for a short distance over the 
dorsal surface of the carapace from the lateral margins. The front is 
about one-third the width of the carapace, punctulated above, with its 
anterior margin sinuated, its antero-lateral angles obtuse and not pro¬ 
minent. The orbital margins are entire, and defined by a raised line, 
which is granulated except near to the front; the inferior orbital 
margin is regularly arcuate, not (as in T. perlata ) angulated near to 
the interior subocular lobe, which is not at all prominent; the tooth, 
also, at the exterior orbital angle is very little developed ; the parts of 
the carapace adjoining the antero-lateral angles of the buccal cavity 
are very distinctly granulated. The eye-peduncles are slender (for a 
species of this genus), and the eyes do not attain the exterior angle of 
the orbit. The exterior maxillipedes are formed as in T. perlata , 
having the ischium and merus of the endognath distally truncated, 
the merus rounded at its antero-external angle, and scarcely emarginate 
at its antero-internal angle. The chelipedes in the adult male are 
unequal, the right the larger ; in both the merus is armed with a 
series of spinules on the anterior margin, and with a somewhat longer 
spine near the distal extremity; the carpus with a spine followed by 
a smaller spinule on the inner margin; the palm is somewhat com¬ 
pressed and nearly smooth, rounded above; the dactyl and pollex are 
denticulated on the inner margins, and have between them, when 
closed, a rather narrow interspace ; the dactyl is slightly arcuated and 
as long as, or rather shorter than, the palm. The ambulatory legs are 
of moderate length, with the fourth to sixth joints compressed, and 
with the superior margins acute; the margins of the penultimate 
joints near to the distal extremity and the dactyli are armed with 
small spinuliform teeth, which on the dactyli are disposed in four 
longitudinal series.
