200 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
the surface is very sparsely punctate. The posterior margin 
is rounded and defined, together with the lateral margins, by a 
continuous, minutely granulated line, the granules of which 
become less distinct anteriorly near the hepatic region. The 
inflected sides of the cephalothorax are quite smooth, pre- 
senting no trace of the thoracic sinus and no granules near the 
base of the chelipedes. 
The outer maxillipeds have the merus-joint a little shorter 
than the ischium-joint and acute at its distal extremity ; the 
exognath is broad, though scarcely broader in the middle than 
the anterior margin of the ischium-joint, with its outer margin a 
little arcuate and minutely granulate, and with an almost straight 
anterior margin. ‘The outer surfaces of the outer foot-jaws are 
minutely punctate. 
The male sternum is smooth in the middle, but granular 
laterally ; in the first joint, which borders the buccal cavity 
posteriorly, the granules are found near the articulation of the 
chelipedes, but separated from their bases by a smooth space. 
In the other joints, the granules are found on those portions which 
border the bases of the legs laterally. The male abdomen is 
smooth, and is quite similar to that of P. Perry, Miers (Trans. 
Linn. Soc. 1877, pl. xxxviil. fig. 21), being narrow and tri- 
angular, with straight margins ; the penultimate joint, however, 
which is scarcely shorter than the antepenultimate, is quite 
smooth, and has no tubercular prominence as in Pseudophilyra 
Perryi, Miers. The lateral margins of the cavity which includes 
the abdomen are also granular, as far as they lie on the first 
joint of the sternum. 
The chelipedes are slender, and similar to those of P. orbi- 
cularis, Bell, being twice as long as the length of the carapace. 
The arms are cylindrical, four times as long as broad, and covered 
on their upper surface with granules, partly arranged in longi- 
tudinal rows; but the distal third of the upper surface is 
nearly smooth, and bears only a few small granules near the 
anterior margin. The under surface of the arm is equally 
granular, the granules extending to near its distal end, but they 
are not arranged in longitudinal series. The wrist is smooth. 
The hands are quite similar to those of P. orbieularis, the palm 
being twice as long as broad, but the rounded inner (anterior 
or lower) margin is covered with small granules of unequal 
size and irregularly arranged. The remainder of the palm is
