are distinctly modern. It may be, however, that the difference in con- 

 ditions of life kept the offshore fishes away from the sheltered archipelago 

 where the diatoms were piled up. 



The species here enumerated are the following (new names in 

 italics) : 



Family PHOLIDOPHORID^. 



1. ETRINGUS SCINTILLANS Jordan. Brown's Canon, Moore's Canon, 



Soledad Pass. 



2. Ganolytes cameo Jordan. Brown's Canon, Soledad Pass, Puente 



Valley. 



Family ROGENIID^. 



3. ROGENIO SOLITUDINIS Jordan. Soledad Pass, Moore's Canon. 



4. Rogenites BOWERSI (Jordan). Brown's Canon. 



Family COBITOPSID^. 



5. Rhomurus fulcratus Jordan. Soledad Pass, Brown's Canon. 



Family SCOMBRID^. 



6. Auxides sanctce-moniccz Jordan. Soledad Pass, Brown's Canon. - * 



Family LIPARID^. 



7. Bulbiceps raninus Jordan. Soledad Pass. 



Family PHOLIDOPHORID^. 



1. Etringus scintillans Jordan.

In my paper on the "Fossil Fishes of California," 2 a new genus of 

 fishes is described under the name of ETRINGUS. Renewed examination 

 of the original type (No. LIII, Stanford Collections, from Brown's 

 Canon) and of numerous variously imperfect specimens from the Miocene 

 of Brown's Canon, Soledad Pass, and Olinda necessitates certain changes 

 in the original account. The rather large thin scales, about 35 in a 

 longitudinal series, are covered with enamel (ganoine), and they are 

 without ornamentation except the thin concentric circuli. The ridge 

 along the side of the abdomen, taken for a lateral line in the original 

 description, is fallacious, apparently due to irregularities in the rock. 

 There is no evidence of a lateral line and no trace of ventral scutes. 

 Apparently none of the scales are especially deepened, and they are 

 nowhere arranged in hard and fast oblique rows, as is usually the case 

 in the related genus, PHOLIDOPHORUS. Vertebrae 14 -f- 23 = 37, well
