48 DR. J. G6. DE MAN ON THE PODOPHTHALMOUS 
The cephalothborax has precisely the same form ag that of 
Actumnus obesus, and is uniformly covered on its upper surface 
with short yellow hairs. The regions are quite indistinct, no 
trace of divisional lines being found; the upper surface is not 
uniformly covered with granules as in A. obesus, but only a few 
acute granules (15-20) are found on the antero-lateral regions, 
which resemble the six granules with which the antero-lateral 
margins are armed, but are much smaller. The front, the gastric, 
cardiac, and intestinal regions are not covered with granules. 
The frontal margin is divided by a small median incision in 
two almost straight lobes, and passes laterally continuously inte 
the upper orbital margin, not being separated by a cleft from 
the internal orbital angles. The frontal or inner part of the 
upper margin of the orbits makes nearly right angles both 
with the frontal and the external, somewhat granular portion 
of the upper orbital margin. The external angle of the orbits 
is formed by a small, acute, spinuliform granule. The antero- 
lateral margins are about as long as the postero-lateral, which 
are smooth and concave; they are armed with six small, acute, 
spinuliform granules, which are arranged in three groups, two 
in each. The inferior margin of the orbits is minutely granular, 
and presents a small triangular hiatus close to the external 
orbital angle. The pterygostomian regions are glabrous and 
nearly quite smooth, presenting only some minute granules near 
the inferior margin of the orbits. ‘Lhe outer surface of the 
maxillipeds, the sternum, and the lateral margins of the abdo- 
men are clothed with yellow hairs. 
The chelipedes are of unequal size, the right chelipede being | 
the larger in all our specimens. The anterior margin of the 
arm, which is very short, the antero-internal margin of the wrist, 
and the upper margin of the hand and of the mobile finger are 
clothed with a row of long yellow hairs. The upper surface of 
the wrist and the outer surface of the larger hand are covered 
with similar yellow hairs, disposed between the granules with 
which they are provided. The larger hand wholly resembles that 
of A. obesus, its outer surface being covered everywhere with acute 
granules, disposed irregularly, those of the middle of the outer 
surface being a little larger: than those of the upper; the 
under margin presents a longitudinal line of granules on the 
inner side, and is clothed with a row of long yellow hairs. The
