median sometimes appearing as two, extending from eye to tail; 
lower one extending from base of pectoral toward tail. The dark 
bands are separated by lighter, sometimes silvery ones, and are often 
broken into blotehes by a tendency toward cross-banding; distinct 
cross bands, however, are lacking except in rare cases. Belly and 
throat often bright yellow. The detail of color pattern is variable, 
but the general form is quite constant, much more so than in the 
preceding species; and the fine, variegated, silvery or other bright 
colored mottlings are always lacking, although young specimens may 
have bright silvery bands. 
Diagram A. Curves of Variation in Fin Rays of Gibbonsia 
elegans and Gibbonsia evides. 
A, B, C—Specimens collected at Monterey, California. 
Continuous lines Gibbonsia elegans, (curves plotted from 160 
specimens) ; broken lines Gibbonsia evides, (from 65 specimens). 
A. Rays of soft dorsal. 
B. Spines in spinous dorsal. 
C. Rays in anal. 
D,E,F. Variations in G. elegans.* 
Continuous lines Monterey specimens, (160) ; broken lines Laguna 
Beach and San Diego specimens, (190).

K. Spines in spinous dorsal. 
F. Rays in anal. 
G, H. I. Variation in G. evides. 
Continuous lines Monterey specimens (65); broken lines Laguna 
Beach and San Diego specimens, (30).

Numbers at the bottom from left to right indicate fin rays. Num- 
bers at the side from bottom to top indicate percentage. The curves 
are plotted on a percentage basis. Not all are drawn to the same 
scale, however, as may be seen. 
Example: In G. the continuous line shows that of the Monterey 
(northern) specimens, 3% have 8 rays, 63% have 9 rays and 
34% have 10 rays. The broken line shows that of the Laguna and 
San Diego (southern) specimens, 10% have 8 rays, 63% have 9 rays 
and 27% have 10 rays. 
Gibbonsia elegans may usually be distinguished from G. evides at 
a glance, by its rich colors, variegated markings, and the presence 
“Specimens from Laguna Beach and San Diego are almost identical, i. e., show almost 
identical variation curves, so are here combined to represent the southern specimens.
