SHORE FISHES OF GALAPAGOS ISLANDS 375 



We have 50 specimens taken at James, Tower, Banington and 

 Seymoui- islands of the Galapagos Archipelago and at Cocos Island. 

 The species was described by Valenciennes from specimens taken at 

 the Galapagos Islands and has since been taken at the Tres Marias 

 and Revillagigedo islands. 



We found the species very abundant at James, Seymour and Cocos, 

 but about Tagus Cove, Albemarle, where most species were numer- 

 ous, we saw only a very few and were not able to secure any 



specimens. 



80. LUTIANUS JORDANI (Gilbert). 



Neomcenis jordani Gilbert in Jordan & Evermann, Fishes North and Mid. 



Amer., 11, 1251, 1898, Panama. 

 Lutianus jordani, Gilbert & Starks, Mem. Cal. Acad. Sci., iv, 1904, 102. 



Range. — Panama, Cocos Island. 



Seventeen specimens from Cocos Island. They are about 230 mm. 

 in length. The vomerine teeth form a diamond-shaped patch of 

 which the posterior sides are considerably longer than the anterior. 



81. LUTIANUS ARGENTIVENTRIS (Peters). 



Mesoprion argentive?itris Peters, Berlin. Monatsbr. 1869, 704, Mazatlan. 

 Neomcenis argentivenfris, Jordan & Evermann, Fishes North & Mid. Amer., 



II, 1260, 1898. 

 Lutianus argentivenfris, Gilbert & Starks, Mem. Cal. Acad. Sci., iv, 1904,

Rajige. — Pacific coast of tropical America ; Cocos and Galapagos 

 islands. 



Six small specimens from Chatham, about 55 mm. long, have a dis- 

 tinct bright blue subocular band reaching from below anterior part of 

 eye almost to posterior angle of opercle, and a dark postocular band 

 reaching from eye as far as the beginning of lateral line. Specimens 

 in the Stanford University collection from Guaymas, 130 mm. long, 

 have the subocular band somewhat broken posteriorly while the upper 

 one is obsolete. In specimens up to this size the eye is on a line with 

 the snout and the angle of the opercle, but in specimens 400 mm. in 

 length, the eye is considerably above a line connecting these 2 

 points. The subocular band in specimens of this size is either absent 

 or apparently represented by a row of spots which bends downward in 

 front of the eye and extends forward toward the snout on a lower level.
