median sometimes appearing as two, extending from eye to tail ; 

 lower one extending from base of pectoral toward tail. The dark 

 hands are separated by lighter, sometimes silvery ones, and are often 

 broken into blotches 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.

A, B, C. Specimens collected at Monterey, California. 



Continuous lines Gibboiiftia elcgans, (curves plotted from 1(50 

 specimens); broken lines Gibbonsia rriWr.s, (from (55 specimens).

Continuous lines Monterey specimens, (!(>()) ; broken lines Laguna

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. 



Extuiipli' . In G. the continuous line shows that of the Monterey

 San Diego (southern) specimens, 10 '/ have 8 rays, 6.'5'/< have 9 rays 

 and 277' have 10 rays. 



Gibboitxin I'li'f/aiis 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.
