Holocanthus strigatus GILL, Proc. Acad. Nat. Sci. Phila. 1862, 243, Cape

Range. West coast of tropical America, Cocos and Galapagos 

 islands. 



We have 36 specimens from Tagus Cove and Elizabeth Bay, Albe- 

 marle, Duncan, Seymour, Harrington, Chatham and Bindloe islands 

 of the Galapagos Archipelago, and from Cocos Island. 



Depth about i^, much greater than given by Jordan and Evermann. 

 Valenciennes's figure is not nearly deep enough. The vertical stripe 

 on the side back of the pectoral is generally widest at the upper end, 

 not thickest in the middle and symmetrically tapering at each end, as 

 figured by Valenciennes. Young examples 90 mm. long, have the 

 soft dorsal and anal less attenuated than in the adults, the pectoral 

 very slightly wider, the depth about the same, while the stripe on the 

 side is not so much widened above. 



The young differ considerably in color from the adults. Vertical 

 bar back of shoulder light blue, body posterior to this bar hazel- 

 brown, crossed by narrow deep-blue vertical stripes one scale wide, 

 anterior to the shoulder bar body and head darker brown without the 

 stripes ; belly lighter brown ; throat dark bluish to base of pectoral ; 

 snout rufous, chin lighter ; iris golden-hazel ; a blue band from isthmus 

 to before eye, another free from first dorsal spine to spine of pre- 

 opercle; opercle blue-bordered; spinous dorsal orange, blue-tipped ; 

 base of soft dorsal colored like back, border blue except at tip where 

 blue is lacking ; pectoral light orange ; spine and first ray of ventral 

 orange, other rays yellow; anal rufous, striped with blue; caudal deep 

 orange, chrome-yellow stripe at base, posterior border of fin bluish.
