162 THE SHORE FISHES. 



the eyed side of head ctenoid, those of other side, when present, merely ciliated; 

 opercle and posterior and inferior borders of preopercle scaleless, except about 

 three rows on upper posterior edge of opercle; head everywhere on eyed side 

 thickly covered with fine pale ciUa; lower lip with a fringe of large cilia; Wind 

 side of head in front with low, strongly ciliated folds or flaps; numerous fine 

 cilia everywhere on the eyed side, anteriorly some of them black, more numerous 

 on the rays of the fins; on blind side cilia are not so numerous on body, groups 

 of them are arranged along the lateral line. 



Color on eyed side, dark gray, body crossed by faint, fine, hardly distin- 

 guishable dusky lines; vertical fins and caudal gradually darker toward margin, 

 with a narrow pale margin ; blind side of head and body white. 



This specimen agrees closely with A. mazatlanus, differing only in the form 

 of the caudal, which is slightly lunate. This character alone and in but one 

 specimen is scarcely sufficient to justify the description of a new species.

Plate 8, fig. 3. 



One specimen 1.62 inches long from Station 4640, Lat. 0°, 39.4' N.; Long. 

 88°, 11' W., taken at surface. This Station is near Galapagos Islands. We 

 provisionally identify the specimen with this species. The identification is not 

 at all certain and is made solely because the species has been recorded from the 

 Galapagos and because it agrees very well in vertical fin rays, the dorsal having 

 100 and anal 80 rays. 



It is a larval form without color-markings; the eye has apparently just
