55 FISHES OF SINALOA. 427 
dark. Ventral reddish, the spine and first soft ray whitish, 
the first ray dark red; when the fin is closed it seems 
reddish, edged with whitish or yellowish, and with a 
blackish line. The dark is fainter in larger specimens. 
It is not impossible that Aehamphoberyx pacilopus Gill 
is the very young of this species. /thamphoberyx leuco- 
pus may be the young of Myripristis occidentalis, which 
has the ventrals plain. 
Family MULLIDE. 
76. Upenus grandisquamis Gill. Cuivo. (Upenus tet- 
raspilus Giinther.) 
This small species, rarely exceeding a foot in length, is 
generally common in the harbor and estuary at Mazatlan, 
where it was found also by Dr. Gilbert. It seems to be 
everywhere common on the coast. 
Color evanescent, olive with two rows of light bluish 
green spots toward back, then a bronze band, then a blue 
streak on level of pupil; 2 or 3 yellowish streaks below 
it. Sides of head golden, with a light green streak for- 
ward from eye and some blue behind eye. A large black 
blotch below last dorsal spine. First dorsal reddish, 
clouded with dark. Second mesially black, edged with 
orange. Caudal and anal red. Ventral and pectoral pale. 
In alcohol much red appears. In lite, sides with curved 
light yellowish brown, cross bands most distinct on the 
silvery lower parts. 
Family SCOMBRIDEL. 
77. Germo alalunga (Gmelin). 
Recorded from near Mazatlan by Lay and Bennett; 
not seen by us, it being probably a migratory fish coming 
in the spring or fall.
