JFirst annual Report 



sible to describe all the various shades and markings found in a 

 random series, but a few of the main color types are here given. 



Although the fishes vary in a rough way to correspond to the pool 

 in which they live, yet it is by no means true that they all agree in 

 any one place. The light and dark shades are almost uniformly 

 found in the pools corresponding, but in color pattern and brilliancy 

 of marking no particular correlation to surroundings holds consist- 

 ently. Especially is this true in pools with luxuriant algae and cor- 

 raline growths, where all sorts of color patterns are found inter- 

 mingled. No evidence of a so-called voluntary change of color by 

 individual specimens was observed. Change in surroundings seemed 

 to have no immediate effect on the color of any individual. 



Figure lOa. Clinocottus analis 



The general body color pattern of this species consists of five or 

 six dark bars extending down on the sides, and usually an irregular 

 dark area covering the upper part of the head. The fins, except 

 ventrals, are all barred with narrow, dark, transverse bands on the 

 rays. Below the body is variously speckled. In other respects there 

 is no uniformity in coloration. 



No. 1. Taken from a specimen three and one-half inches long. 

 General color dark ; bands on dorsum not conspicuous, faded out in a 

 few minutes. Ground color of under parts pale bluish green, broken 

 by numerous round silver spots. Dorsal fin with an apical row of 

 blood red spots on the membrane between the rays ; caudal salmon 

 color with an apical row of red spots like that of dorsal; pectoral 

 with a row of silver streaks on the base of rays, remainder streaked 

 with brown. Cheeks with numerous dots and stripes of salmon pink.
