the head and the belly of a fine orange yellow ; on the snout 
there are two white longitudinal stripes, edged with black, one 
placed laterally, and extending over the entire length ; and the 
other on the upper part, and only on the second half of the 
snout ; on the head there are also two similar stripes, one arched 
and extending from the posterior edge of the eye to the end of 
the operculum, on the upper part of the head, and the other 
similar but broader, and almost straight, extending on the side, 
in continuation to the one of the snout ; the upper one extends 
on the back to the end of the trunk ; below are numerous, very 
small, rounded white spots, surrounded by a black circle (they are 
more visible on the dried than on the living specimens) ; the 
dorsal has a greenish tinge ; the eye is white, with a green mark 
on its upper edge. 
I have only seen one specimen, in the month of September, 
it was eight and a-half inches long. 
Not A. — I believe this to be the Semistriatus of Kaup ; but the 
snout seems considerably longer. 
UEOCAMPTJS. 
Formed by Dr. Grunther on the following characters : — “ Body 
elongate, compressed, with distinct longitudinal ridges ; the 
upper edge of the trunk continuous with that of the tail j 
lateral line continuous with the lower caudal edge ; tail elongate, 
quadrangular, tapering ; pectoral and caudal fins developed ; the 
dorsal is placed entirely on the tail, at a great distance behind 
the vent.” 
The only sort known is from Manchuria, but the Australian fish 
I here describe appears to me to belong to this genus. 
TJEOCAMPUS CAEINIliOSTEIS. 
8nout turned rather upwards, very short, being contained 
once and a-half in the diameter of the eye, and nearly three times 
in the length of the head ; it is not abruptly separated from the 
forehead, and goes slanting to its extremity ; the supraorbital 
ridges are very strong, and sometimes converge in front to form 
the medium ridge of the snout ; in other specimens there is 
between them a rounded sharp ridge ; there is a short spine at 
the anterior angle of the eye ; the eyes are very prominent ;
