is only half as broad as the internal ridge. Lastly, two parallel, 
slightly oblique, elevated lines are seen near the third and the 
fourth antero-lateral teeth, the posterior of which is twice as broad 
as the anterior. Although I have described the upper surface as 
being smooth, I may, however, remark that it is minutely granular 
near the postero-lateral margins, which are but little longer than 
the antero-lateral. The distance between the third antero-lateral 
teeth is three times as great as the distance between the internal 
orbital angles. The front is somewhat declivous, and consists of 
two slightly oblique lobes, which are separated from one another 
by a small triangular incision ; these lobes are rather prominent 
-in the middle, and their minutely granular anterior margin is 
broadly emarginate towards the external angle, so as to consti- 
tute a small tooth at the external angle of each lobe. Each 
frontal lobe is marked above with a slightly arcuate, transverse, 
granular line, and is covered with some granules between this 
line and the anterior margin. The frontal lobes, which therefore 
somewhat resemble those of some species of Leptodius, are sepa- 
rated by a small notch from the little prominent, internal orbital 
angles. The orbits are transverse, being a little broader than 
long. The granular upper margin of the orbits is marked with 
two fissures on the external half; the granulated or minutely 
denticulated under margin presents a strong, rather obtuse, 
tooth at the internal angle, which is a little more prominent 
than the internal angle of the upper margin, projecting nearly 
as much forward as the small external teeth of the frontal 
lobes. The infraorbital margin is marked with a small trian- 
gular hiatus close to the little prominent external angle of the 
orbits. 
The antero-lateral margins are armed with four prominent teeth, 
including the external orbital angle. The first tooth is rather 
broad, and its external margin is slightly emarginate ; the second 
tooth much resembles the first, but it is a little narrower and 
more triangular; the third tooth is the most prominent of all, 
being triangular, rather acute, and directed obliquely forward ; 
the fourth tooth resembles the third, but is much smaller 
and much less prominent. The last two teeth are somewhat 
carinate and granular above, and the external margins of all the 
antero-lateral teeth are granular. 
The inflected sides of the cephalothorax are somewhat granular 
and hairy, but the pterygostomian regions do not present a
