occiput. A bluish band along th'e middle of the side of the tail, 

 terminating in a blackish spot at the root of the caudal fin.

The height of the body is contained thrice and a fourth in the total 

 length (without caudal), the length of the head thrice and two-thirds. 

 The upper profile is a little concave above the occiput. Snout not 

 shorter than the eye, the diameter of which is contained once and 

 two-thirds in the width of the interorbital space. Orbit without 

 adipose eyelids. Caudal lobes scarcely longer than the head. The 

 origin of the dorsal fin is a little nearer to the extremity of the snout 

 than to the root of the caudal, and corresponds to the fourteenth scale 

 of the lateral line ; its height is much less than the length of the head. 

 The pectoral terminates at some distance from the ventral, its length 

 being two-thirds of that of the head. The ventral does not extend 

 to the vent, and its base is below the middle of the dorsal. Belly 

 not keeled behind the ventrals. Silvery, vertical fins more or less 

 blackish ; a round black spot on the end of the lateral line.

6. Curimatus rutiloides.

 D. 10-11. A. 10. L.lat. 50-53. L. transv. -^p. 



The height of the body is one-third or somewhat less than one- 

 third of the total length (without caudal), the length of the head 

 two-sevenths. The upper profile is not concave. Eye with an ante- 

 rior and posterior lid. The pectoral does not quite extend to the 

 base of the ventral, nor does the ventral reach to the vent — the ventral 

 being rather shorter than the pectoral. Coloration uniform. (Kner.)

Note. — Charax no. 378, Gronov. Zoophyl. i. p. 123, is generally 

 quoted as a synonym of this species, but Gronow speaks of " squamae 

 minutissirnae," and therefore I consider it as identical with Curimatus 



* Valenciennes states in the formula of the fins A. 11, which is evidently an 

 error ; he has confounded it with the formula given for C. ciliatus, where he 

 puts A. 9 instead of A. 11.
