41S 



were liere larger, darker, and more crowded tlian elsewhere, and situated in several strata. The 

 under sides of the arms and fins were colored like tlie body, except that the spots were smaller 

 and much less numerous. 'J'he suckers were pure white. The eyes were dark, blueblack, 

 surrounded by an iridescent border. — The colors change constantly, when living or recently 

 dead, l)y nieans of the continual contraction and dilation of the chromatophores. The different 

 tints pass over the surface like bhishes.« 



»In specimens recently preserved in alcohol the same pattern of coloration is usiially 

 visible. The dark dorsal band on the body and head, and the dark patches above the eyes, 

 as well as smaller dark patches in front of the eyes, can be plainly seen. In the darker parts 

 the chromatophores are much crowded, and have a purplish brown color, varying to chocolate 

 -brown in specimens longer preserved. On other parts of the body the chromatophores are 

 more scattered and usually reddish brown in color, with a circular or elliptical outline; when 

 expanded, the larger ones are about 1 mm in diameter. The under surfaces of tlie fins, siphon, 

 head, and arms have fewer and smaller spots, and are, therefore, lighter colored, and appear 

 nearly white when these spots are contracted.«
