79 FISHES OF SINALOA. 451 
narrow, 34 width of eye. Interorbital area convex, its 
width 4% in head. Nostrils small, the posterior scarcely 
the larger, separated from the anterior by one diameter. 
Angle of preopercle scarcely salient, but provided with 
coarser teeth; a small sharp notch above it. Opercular 
spine flat and divided into about six teeth at the end. 
Gill-rakers moderate 9+-18. Scales moderate, scarcely 
ctenoid. Dorsal spines low, the outline of the spinous 
dorsal gently convex, the fourth spine longest, 3 in head. 
Soft dorsal high, its outline angular, the tenth ray pro- 
duced, 1% in head. Anal fin formed as in J/ycteroperca 
falcata, its seventh ray produced and falcate, 14 in head, 
its posterior outline concave. Caudal subtruncate, the 
outer rays slightly produced. Pectoral 134 in head. 
Color plain dark olivaceous, the edges of the fins 
scarcely darker ; no evident markings on body. 
115. Paralabrax maculatofasciatus (Steindachner). 
,CABRIMIAL PINTA: 
Rather common at Mazatlan. This is one of the very 
few northern species which extends its range thus far to 
the southward. It is found in some abundance about San 
Diego, and its center of distribution is probably between 
Mazatlan and San Diego, these two places being the lim- 
its of its range, so far as now known. 
116. Diplectrum radiale (Quoy & Gaimard). 
This small species is about a foot in length and is gen- 
erally common on the Coast. It is apparently not very 
abundant at Mazatlan, the few specimens seen by us be- 
ing all taken in the Astillero. 
Much cherry red on head and fins in life, sides salmon 
color, streaks on head greenish.
