Range : Southern Chili. 



I have seen no specimens of this species. The following is an abridgment of 

 Girard's description: 



Head 4; depth 3-4; D. 10; A. 14. Eye 3 in the length of the head; depth of 

 caudal peduncle 2.5 in the greatest depth. 



Snout short and rounded; eye rather large. Maxillary teeth very small and 

 few. Dorsal fin higher than long. Caudal forked. Anal nearly as deep as long. 

 Ventrals and pectorals slender. Scales proportionately very large, higher than 

 long. A silvery band along the middle of the flanks, margined above with black. 

 Fins unicolor, olivaceous. 



A small fish of a rather short appearance, in spite of the slenderness of the 

 peduncle of the tail. Dorsal and ventral fines equally arched. Body very much 

 compressed; mouth small and slightly oblique; maxillary extending to a vertical 

 line immediately in advance of the anterior rim of eye when the mouth is closed. 

 Dentary teeth much larger than those on the intermaxillaries. Their form is 

 flattened, dilated towards their upper edges, which are provided generally with 

 five subconical points, the middle one being the longest, giving them the appearance 

 of digits. 



Origin of dorsal nearer base of caudal than tip of snout; dorsal much higher 

 than long, its upper edge rounded or subconvex. The adipose is slender, nearer 

 to the base of the caudal than to the posterior edge of the dorsal and consequently
