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 

 arid 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. 



Nota. — I believe this to be the Semistriatus of Kaup ; but the 

 snout seems considerably longer. 



UKOCAMPTTS. 



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 ; 

 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. 



TTROCAMPUS CARINIKOSTRIS. 



Snout 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 ;
