process of its posterior border is more acute; mesially it is devoid of hairs, but
laterally it is extremely hirsute. The anterior pleural lobe is distinct, but the interpleural
portion of the line that marks it off from the rest of the carapace is not
tuberculated as in T. edwardsi ; neither is the inflected portion of the carapace so
distinctly rugose nor so thickly covered with hairs. Of the chelipedes the right
exceeds the left in size in the only adult specimen in my possession; the outer, or
more strictly speaking the posterior face of the meropodites is smooth, devoid of
hairs, except towards the dorsal edge, which is densely covered with bundles of hairs
and but slightly rugose. The carpopodite is armed in the usual Way with a spine,
beneath which is a short bilobed spinule; its upper surface roughly punctate; an
impression is to be observed at its distal articular end, which is not more than
ordinarily thickened. The propodite is coarsely punctate, its lower border is longitudinally
concave, its prolongation is externally grooved, and so is the dactylopodite
with which it is in contact throughout its whole length. The ambulatory legs are
robust; the ridges of all their joints are thickly covered with bundles of hairs; the
penultimate joints are similar to those of Telphusa andersonia/na.

Carapace slightly broader than long, tumid, punctate, extremely convex in
every direction, with an areolation similar to that of the three last described species,
but the meso-gastric lobe is almost confluent anteriorly with the proto-gastric, and
this latter is marked by a short branch running off from the cervical suture at right
angles to i t ; the cardiac is separated from the posterior half of the branchial area;
the epi-gastric lobes are prominent, anteriorly wrinkled, and extend beyond the line
of the rest of post-frontal ridge; anterior branchial lobe and post-frontal crest
rugose; the latter is slightly indented by the cervical suture, and continuous from
the epi-gastric lobes to the minute epibranchial teeth; antero-lateral margins greatly
inclined with minutely denticulated crests; postero-lateral margin marked with
oblique wrinkles which assume a tubercular character as they pass forwards on to
the inflected portion of the carapace, and the posterior pleural lobes which, where
they form the peristoma, are completely covered with round, polished tubercles,
disposed in pairs; the anterior pleural lobe presents a few scattered tubercles, and
is cut off from the posterior pleural and from the inflected region of the carapace
by a beaded line. Front broad, deflexed, coarsely granulated, marked by the prolongation
forwards of the meso-gastric furrow. The epistoma presents the same
characters as that of Telphusa a/ndersomana, except that its anterior margin is
distinctly crenulated. The orbits and their external angles are crenated.
Chelipedes subequal; meropodites with their posterior faces and angles very
rugose; carpopodites, above rugose, armed internally with a short blunt tooth,
above and below which are some smooth tubercles; propodite externally convex and
rugose; internally, especially near the lower margin, above, and below tuberculated;
the upper margin of the dactylopodite is rounded, and presents a short row of
tubercles at its proximal end; the pincers are marked on every face with longitudinal
rows of puncta, and their arms can be almost completely apposed.

The carapace is much broader than long, the greatest breadth being measured
between the points of the last epibranchial tooth, extremely convex, smooth, punctate,
and perhaps finely granular under an ordinary lens; The branchial lobes are
greatly swollen and are not sub-dividied into anterior and posterior divisions; the
mesial crescentic portion of the cervical suture is distinctly marked and continued
nearly to the level of the last epibranchial tooth, where it ends to appear again
opposite the second tooth, whence it passes to the edge of the post-frontal crest,
which it but faintly indents. The post-frontal ridge is well marked, and, between
the point at which its edge is notched by the passage across it of the cervical suture
and the anterior epibranchial tooth, is crenulated; the cardiac lobe is marked off
from the branchial by two shallow almost linear depressions on each side of the
middle line, and in front from the uro-gastric by a line curving almost concentrically
with the convexity of the cervical suture. The epi-gastric lobes are slightly
wrinkled or foveate anteriorly, and advanced beyond the line of the post-frontal
crest as in Paratelphusa spinigera, and separated from one another by the meso-gastric
suture,. which rapidly bifurcates as it passes backwards, appearing as a short
Y-shaped impression on the carapace, the space intercepted between the arms of the
Y being the point of the narrow anterior prolongation of the meso-gastric lobe.
The antero-lateral margins are inclined and armed, not counting the blunt
extra-orbital tooth with its curved external margin, each with four acute, spiniform
epibranchial teeth, of which the most anterior is the largest; the rest are equal in
size to, and equidistant from, each other; from the last a short well-defined keel,
obscurely crenated on its inner edge, passes backwards and inwards on to the carapace,
which is marked with a few small straggling tubercles along the line of the
epibranchial spines. Front very broad, especially at base, punctate, finely granular
