Family SCORP.ENILVE. 

 Genus Sebastodes Gill. 



42. Sebastodes rosce Eigenmann (Zoe, I, p. 16, 1890). 



Preopercle of a fish about a foot long. Three lower preoper- 



cular spines subequal and equally spaced, all directed downward 



and backward. Preopercle much heavier than in Sebastodes ro- 



saeeus, the nearest living species. Three pits leading into mucous 



canals, decreasing in size backward on anterior half of first spine. 



A large pit between first and second preopercular spine, another 

 between second and third, and two smaller ones on anterior half 



of second spine. ( Eigenmann.) 



Tertiary rocks at Port Harford. San Luis Obispo County. 



Family LUVARIM. 



43. Luvarus species (?). 



In the Los Angeles High School is a specimen of a large fossil 

 fish, thirty-four inches in length, so poorly preserved that only 

 the general form and the robust vertebra? are shown. 



It is apparently a scombroid fish, that is, one belonging to 

 some mackerel-like family. The genus Luvarus, of which a spe- 

 cies, Luvarus im-perialis Rafinesque, occurs on the coast of Cali- 

 fornia, is suggested by the character of the vertebra?. The speci- 

 men might, however, belong to any one of a dozen genera living 

 or extinct. 



The specimen was found by Mr. J. Z. Gilbert, teacher of 

 Zoology in the Los Angeles High School, and I am indebted to 

 him for the accompanying photograph. Mr. Gilbert states that 

 the specimen was found on the "Third Sea Beach," at about 

 2,000 feet from the lighthouse on Point Firmin, southwest of San 

 Pedro. There occur five moon-shaped sea beaches from the light- 

 house to the foot of the breakwater. The specimen was from a 

 rock, not in situ but near a ledge of similar structure and appear- 

 ance. The matrix is of a hard volcanic material overlying readily 

 cleavable sandstone. The specimen represents probably only 

 about one-half of the length of the animal when living. There 

 are twenty vertebra? plainly visible, each measuring one and one-
