DISCOVERY REPORTS 



1 find that nearly all these characters are subject to considerable variation. The caudal 

 peduncle is from 4 to 7 times as long as deep ; the two dorsal fins are separated by from 



2 to 5 scales ; the series of small spines on the eyeball is present in all the specimens, 

 including the types of A. chiloensis; the diameter of the eye is 3 to 4J in the length of 

 the head ; the interorbital width is § to £ of the diameter of the eye ; the number and 

 size of the barbels varies exceedingly ; and the vent is sometimes opposite to the middle,

sometimes opposite to the posterior parts of the pelvic fins. The form and extent of the 

 spines on the head and body is also subject to some variation. There are nearly always 

 5 or 6 distinct dark cross-bars on the back, with other less definite dark markings on 

 the sides and on the nape; the pectoral fin has a broad dark cross-bar distally and 

 another across its base; the caudal has 2 similar bars and a narrow pale posterior 

 margin ; the dorsal fins are plain or irregularly marked with darker ; the anal is similar, 

 or sometimes with some vivid white patches ; the barbels are all pure white.

This species is closely related to C. pallidus (Vaillant) from Orange Bay, but the 

 latter is said to have only 20 rays in the pectoral fin, which is apparently not notched. 

 The type of C. pallidus is 42 mm. in total length.
