origin nearer mandible tip than caudal base by snout length. 
Anal well behind dorsal, last two rays little enlarged. Pec- 
toral (damaged) apparently reaches dorsal? Ventral inserted 
little nearer caudal base than eye front (damaged), reaches 
2/5 to anal. In alcohol brownish on back, sides and lower 
surface, with eye, pale brassy. Fins pale. 
Two from Callao, 125 to 223 mm. long (caudal broken). 
Although in poor condition they agree with Regan's account.5 
A third example, same data, 90 mm. long, is in very poor 
oreservation. 
In this connection we have examined a dried skin 352 
mn. long from Valparaiso, Chile, now in the Commercial 
Museum of Philadelphia. It shows: Head 3 =. depth 4; D. 4111, 
17; A. 1117, 15; scales 50 in lateral series to Caudal base; 
14 scales transversely at dorsal origin: snout 33 in head; 
eye 4; maxillary 2 2/5; interorbital 4 1/3. Maxillary reach- 
es pupil. Opercular striae strong. 
Clupea advena Philippi 6 is undoubtedly a synonym.
