to run in a more oblique manner, the turn at the anterior inferior 
angle thus becoming more obtuse. On the narrow ventral 
scales this obliquity of the ridges is much more marked. The 
enlarged scales anterior to the anal fin have a very character- 
istic sculpture, the ridges running inwards and backwards to 
meet one another up the central axis of the scale. No fins are 
shown, but certain scattered fin rays would point to the fact 
that they were distantly articulated. 
Remarks. — From the general character of the scales — they 
being " large and thin " — also from the general resemblance 
of their sculpture to that of JR. fusiformis Traq., I place the fish 
in the above genus. As regards specific distinction, although 
in scale sculpture this sj)ecies somewhat resembles that of 
R. fusijormis Traq.. still in comparing the two the distinction 
is at once apparent. On account of the " handsome " character 
of scale sculpture, the specific nomen elegans " is proposed.

Description. — Length about 15 cm. 
The head bones are ornamented with well-marked, slightly 
undulating ridges which frequently branch ; on the opercular 
bones they run more or less obliquel}^ across the bones : on the 
maxilla the sculpture is very characteristic, viz., the ridges run 
for some distance parallel with the upper margin of the bone ; 
they then turn downwards and run with frequent branching 
towards the dentary margin where they become very numerous, 
and some being divided transversely, there is here an appearance 
of tuberculation ; on the mandible the ridges run obUquely 
upwards and forwards to cut the dentary margin at an acute 
angle. On the bones of the shoulder girdle the ridges run in 
a direction more or less parallel to the long axes of the bones. 
The scales are of moderate size ; those of the flank are higher 
than broad ; posteriorily they become more oblique and equi- 
lateral ; whilst towards the dorsal and ventral surfaces they are
