370 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [28] 
This species is not rare about Mazatlan. The specific name (Gavi0s; 
ov Aor) is intended to allude to the yellow color of its lips and gums. It 
is closely related to Cestreus albus, a species which seems to replace it 
farther south.

Habitat—Pacific coast of tropical America; Panama. 
This species is not rare at Panama. Like the others of the genus, it 
isa food-fish of importance. Specimens from Panama are in the museum 
at Cambridge.

Habitat.—Pacifie coast of tropical America; Panama to Peru. 
This species is not rare about Panama, where specimens were obtained 
by Professor Gilbert. A specimen collected by Prof. Alexander A gas- 
siz, at Panama, is in the museum at Cambridge.

Ololithus californiensis Steindachner, Ichthyol. Beitr., ili, 31,1875 (Lower California). 
Habitat.—Coast of California, north to San Francisco. 
This species is one of the largest in size of the Sciznoid fishes, reach- 
ing a weight of 60 to 70 pounds. Its flesh is more firm than that of 
most of the other species of Cestreus, but its quality is searcely less 
delicate than that of the weak-fish. 
The young fishes are somewhat different in color from the adult, being 
marked by two or three distinct dusky cross-bars on the back and sides. 
These young fishes are often taken by fishermen to be a distinct species, 
and called sea-trout. Such specimens have been described by Dr. 
Steindachner under the name of Otolithus californiensis. Typical exam- 
ples of this nominal species, from San Diego, are in the museum at Cam- 
bridge.
