50 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
covered with 30-35 perliform granules; the granules of the gastric 
region are not so numerous anda little less prominent, and a 
few small granules are observed immediately behind and close to 
the arcuate line of granules which I have described above. When 
the upper surface is examined with a sufficiently strong magni- 
fying-glass it appears covered everywhere, anteriorly as well as 
posteriorly, with innumerable microscopic granules. A few short 
hairs are also sparsely distributed over the anterior half of the 
cephalothorax. The front, which is strongly deflected, measures 
about a third of the breadth of the cephalothorax. It is much 
advanced and divided by a small median, triangular incision 
into two rounded oblique lobes, the anterior margins of which 
are somewhat crenulate or uneven, and nearly continuous with 
the upper orbital margins, being separated from the internal 
angles of the orbits by a small and scarcely distinct cleft. The 
upper margin of the orbits is entire and covered with minute 
pearl-shaped granules, and the external angle of the orbits is very 
little prominent. The entire inferior margin of the orbits pre- 
sents, close to the external angle, and separated from it by a narrow 
fissure or hiatus, a dentiform lobe which projects a little more 
forward than the external angle of the orbit itself. The internal 
lobe of the inferior orbital margin is dentiform and obtuse. The 
internal orbital hiatus is occupied by the peduncle of the external 
antenna, the penultimate joint of which nearly reaches the front. 
The antero-latera] margins of the upper surface of the cephalo- 
thorax are scarcely longer than the postero-lateral, and are divided 
into five, little prominent, broad (=long) dentiform lobes, in- 
cluding the scarcely prominent external orbital angle. The third 
or middle lobe is the broadest (or longest) of all, the second and 
the fourth are a little broader (or longer) than the first (external 
angle of the orbits), the fourth being rather acute, and the last 
antero-lateral tooth is dentiform and also rather acute. The 
two last antero-lateral teeth are slightly carinate above, the carinz 
being minutely granular; the granular carina of the fifth tooth 
is directed backward and slightly inward, and terminates at the 
postero-external end of the curved line of granules, which de- 
fines the antero-lateral from the postero-lateral regions, ag igs 
described above. : 
The inflected sides of the carapace, as the pterygostomian, 
subhepatic, and subbranchial regions, are nearly quite smooth; the
