ay FISHES OF SINALOA. 409 
between preopercle and base of caudal. Teeth strong, 
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.
