SHORE FISHES OF GALAPAGOS ISLANDS 413 



The color of the different specimens varies considerably but they ap- 

 pear to be all I species. Two specimens, when fresh, were colored 

 as follows : (i) above dusky, sides stone gray spotted with blackish ; 

 belly white; lips faint pinkish; iris golden; pectoral yellow-olive; 

 caudal bluish-dusky ; dorsal dark like back ; anal pinkish-white; (3)

149. TETRAODON SETOSUS (Smith). 



Tetraodon setosus Smith, Bull. Cal. Acad. Sci., 11, 6, Nov. 13, 1886, Mexico. 

 Ovoides setosus, Jordan & Evermann, Fishes North and Mid. Amer., 11, 

 1739, 1898; ibid., Check-hst, 426. 



Range. — West coast of Mexico ; Revillagigedo, Clipperton, Cocos 

 and Galapagos islands. 



We have 7 specimens of an Ovoides which differ somewhat from 

 one another, but all appear to be O. setosus. One is from Seymour 

 Island of the Galapagos Archipelago, and the others from Clipperton 

 and Cocos islands. 



Head 3 in length (not 4 as in Jordan and Evermann). The specimen 

 from Seymour is almost smooth, the skin having inconspicuous asper- 

 ities, and is larger than the others, being 250 mm. in length. Some of 

 the others have the ventral surface thickly covered with small, short, 

 stiff setce, while still others have almost the entire body beset with setae 

 of this sort. 



The color is very variable ; the following are some of the varieties : 

 (Seymour specimen) above deep orange, back blackish, belly cream- 

 yellow, sides, top of head and snout spotted with black; lips grayish, 

 livid-spotted; fins inky-black with livid white spots; above eye spots 

 like those on fins; (Cocos specimen) above dark brown, grayer on 

 belly, fins same; anal, dorsal and pectoral light-tipped, all fins spotted 

 with white ; body covered with minute purplish spots. Another speci- 

 men is everywhere regularly and closely spotted with small round equal- 

 sized, white spots on a plain dark ground. Some are almost plain 

 dusky, the spots being obsolete. Still others are plain pale yellow with 

 a few (12 to 15) small black spots scattered over the body, mostly on the 

 dorsal surface.
