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 RhaDiphoberyx -pozcilopus Gill 

 is the very young of this species. Rhamfihoberxx leuco- 

 ■pus, may be the young of Myripristis occidentalism which 

 has the ventrals plain. 



Family MULLID/E. 



76. Upenus grandisquamis Gill. Chivo. ( Ufienus tet- 

 raspilus Gunther.) 



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 life, sides with curved 

 light yellowish brown, cross bands most distinct on the 

 silvery lower parts. 



Family SCOMBRID/E. 



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.
