50 DE. J. G. DE MAN ON THE PODOPHTHALMOUS 



covered with 30-35 perliform granules; the granules of the gastric 

 region are not so numerous and a 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 suflBciently 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. Tbe 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 

 antennae, the penultimate joint of which nearly reaches the front. 

 The antero-lateral margins of the upper surface of the cephalo- 

 thorax are scarcely longer than the postero- lateral, and are divided 

 into five, little prominent, broad (=loug) 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 carinse 

 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 p ester o-lateral regions, as is 

 described above. 



The inflected sides of the carapace, as the pterygostomian, 

 subhepatic, and subbranchial regions, are nearly quite smooth ; the
