72 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
Immediately behind the external angles of the front, the 
smooth upper orbital margin presents a small short oblique crest 
and more outward two fissures; the external angle of the median 
lobe, situated between these two fissures, projects a little forward, 
though not forming a tooth. The under margin of the very large 
orbits also presents a fissure, and appears minutely denticulate 
between the latter and the large rounded internal lobe, which 
projects even more forward than the frontal teeth. 
Whilst the left antero-lateral margin of the carapace is pro- 
vided with nine teeth, the right presents only four between 
the external orbital angle and the terminal spine; these teeth 
evidently successively appear during the growth. The terminal 
spines are comparatively nearly as long as in Wept. rugosus, 
measuring about one third of the length of the cephalothorax ; 
they are directed transversely outward and slightly forward, 
whereas in VV. rugosus their direction is backward. The lateral 
angles of the posterior margin terminate each in a short acute 
spinule, directed outward and upward. The subhepatic regions 
of the carapace are a little hairy, and are fringed along the antero- 
lateral margins with longer hairs. 
As regards the shape of the female abdomen, I refer to the 
ficure of Neptunus gladiator published by de Haan (Fauna 
Japonica, pl.i. fig. 5), which wholly agrees with that of this 
SPeCles. 
The somewhat hairy anterior legs are comparatively as short 
as in Nept. rugosus, and the arms extend but little beyond the 
antero-lateral margins of the carapace, and do not reach to the 
point of the great terminal spine. The anterior margin of the 
arms bears three acute, somewhat curved spines, the median one 
of which is found exactly on the middle of the margin; the 
proximal spine is seen immediately behind the median spine, but 
the distance of the distal spine from the latter is somewhat 
greater. The posterior margin of the arms is provided with two 
spines, a larger spine at the distal end and a somewhat shorter 
one close behind it. The wrist is armed at its internal angle 
with a large acute spine, and a smaller one is found on the middle 
of its posterior margin. The hand is armed with two spines, one 
on the outer margin of the upper surface, close to the articulation 
with the wrist, the second a little beyond the middle of the in- 
ternal margin. A small dentiform tubercle, moreover, is found 
at the distal end of the outer margin, above the articulation of
