in advance of the anterior margin of the eye. The teeth are 

 extremely small in both jaws, conical and arranged in se\eral 

 rows anteriorly. They are also present on the \omer, but the 

 palatines and tongue are smooth. 



The scales are of somewhat peculiar construction, consist- 

 ing of two distinct parts separated by a constriction at either 

 end. 



The anterior portion is finely striated vertically, and lies 

 flat upon the body. The posterior half is trilobed, and bears 

 only five or six crenulated lines ; it rises abruptly from the 

 other portion and curls over upon the following scale, so that 

 closed channels are formed beneath each transverse row. At 

 the bases of the dorsal and anal fins the scales are slightly 

 enlarged and rounded and armed with rows of denticulations. 

 From the throat to the ventral fins there are two rows of 

 angular scales defining a flattened ventral surface on 

 which all the scales have denticulated edges. Behind the 

 ventrals there is a deep groove, into which the fin can be 

 folded, but its edges are not provided with specially modified 

 scales. The lateral line is strongly arched anteriorly. A 

 large triangular patch of scales covers the cheek, but the 

 rest of the head is bare. The vent is situated somewhat in 

 advance of the middle of the ventral groove. 



The first dorsal fin commences vertically over a point mid- 

 way between the ventral and anal fins. The first spine is very 

 short, the second, third and fourth are subequal and slightly 

 longer than the eye. The rays of the second dorsal increase 

 regularly in length to a point behind the middle of the fin, 

 where they are a little shorter than the longest spine ; thence 

 they decrease evenly backwards. First anal spine very stout 

 and almost immovable and longer than the second, which is 

 minute. The rays similar in form to those of the dorsal. 

 Ventral spine strong, tlie longest rays not reaching to the anal 

 spine. Pectorals rounded, the third ray longer than the eye. 

 Caudal slightly emarginate, the outer rays almost twice as 

 long as the eye. 



Colour. — Silvery. First dorsal, ventrals and end of caudal 

 black. Iris golden. 



A very young specimen 39 mm. long differs only in having 

 a deeper and more angular body, the depth being 13 in the 

 length to the hypural. It is marked with large scattered 

 darker blotches, the most conspicuous of which are two at the 

 base of the anal fin. 



Compared with specimens of ('. ctustralis of the same size, 

 this species is at once distinguished by its much larger eye 

 and its short dorsal and ventral fins. In ('. australis these are
