length. The orbit is nearly circular, and its diameter (0.05) equals the 

 length of the snout (0.05) and the width of the interorbital area (0.05). 

 The snout projects far beyond the lower jaw, the extremity of which 

 just passes the vertical from the anterior margin of the orbit. The 

 maxillary is dilated above the mandibular joiut, rather tapering behind, 

 and extends to the gill-opening. The gill-rakers are fine, setiform, not 

 longer than the eye (0.05); about twenty-five on the lower branch of the 

 outer branchial arch. 



The origin of the dorsal fin is in front of the middle of the body (0.45 

 from the snout), and directly above the extremities of the ventrals. The 

 length of the first ray (0.06) is half that of the second (0.12), which 

 nearly equals the length of the base (0.11). The origin of the anal is 

 at the middle of the body (0.51 from the snout), and below the posterior 

 dorsal rays ; its greatest height (0.11) nearly equals that of the dorsal. 

 The length of the middle caudal rays (0.08) is two-fifths of that of the 

 outer rays (0.20). The length of the pectorals (0.11) equals the length 

 of the base of the dorsals (0.11), the extremities reaching to the origin 

 of the ventrals. Length of ventrals, 0.09 ; and their distance from 

 snout, 0.35. 



Color: — Back and sides brownish; belly white; a broad, clearly-defined 

 lateral band of silver as wide as the diameter of the orbit (0.05). 



Eadial formula:— D. 13-14, A. 23-24. Length, 2.G8 inches (O'^.GS).
