 sharp, unequal in both jaws: small teeth in patches on 

 palate and tongue. Maxillary pointed behind, reaching 

 middle of eye. 



Color bright silvery, bluish above ; a very distinct black 

 spot at shoulder on level of eye, two-thirds diameter of 

 eye; chin and nose black. Fins all pale, with no yellow; 

 a trace of a broad diffuse, lateral streak of silvery, most 

 distinct in young. Upper ray of pectoral dusky, some 

 pale olive spots on back, very faint. 



Very many specimens taken, the longest 5^ inches in 



length. 



Family ENGRAULIDID^. 



44. Stolephorus miarchus Jordan & Gilbert. 

 Obtained by Dr. Gilbert in the open water about Ma- 



zatlan; not found by us. These translucent type speci- 

 ments are apparently immature, but the small number of 

 anal rays would indicate that it is a species distinct from 

 any other now known. 



The immature or larval specimens obtained by us in 

 the open sea have the fin-rays of Stolephorus ischanus 

 and must belong to that species. 



45. Stolephorus exiguus Jordan & Gilbert. 

 Originally found by Dr. Gilbert in the Astillero at Ma- 



zatlan; not seen by us. 



46. Stolephorus curtus Jordan & Gilbert. 



Rather common in the Astillero at Mazatlan, where it 

 was originally found by Dr. Gilbert. Numerous speci- 

 mens taken by us. 



47. Stolephorus ischanus Jordan & Gilbert. 



Very common in the Astillero at Mazatlan, where it 

 was originally found by Dr. Gilbert. Many specimens 

 obtained.
