LOMPOQUIA 49 



The species is named for Dr. Harry Hagar, long interested in the 

 palaeontology of Southern California, associated with Dr. Gilbert in 

 the discovery and exploration of the fossil beds of Rancho La Brea, 

 where many extinct mammals were found buried in asphalt; these 

 described by Dr. John C. Merriam.

Type (No. CXXXIX) from Lompoc, Mr. Edward J. Porteous. A 

 specimen, of which about six and a quarter inches from the snout to the 

 end of dorsal is preserved. 



The form is slender, perch-like in general appearance. The head 

 (2 l / 2 inches long) is 2 3 / 7 times in length to end of dorsal fin and a little 

 greater than depth of body at front of dorsal fin. The head is not well 

 preserved, its bones apparently all entire and apparently somewhat cavern- 

 ous ; profile above not depressed ; the nuchal region low ; the line from 

 the bluntish snout to the dorsal nearly straight. The mouth seems rather 

 short, its cleft about three in head, but the lower jaw is strong and as 

 long as the upper. No teeth visible; preopercle with its posterior limb 

 upright. 



Pectoral fin short and rather narrow, inserted high, with about 

 eighteen slender rays, forming an angle below, the part preserved about 

 four in head. Ventrals inserted well behind pectoral, at a distance nearly 

 equal to their own length ; the rays I, 5, the length about equal to that of 

 pectoral. 



Spinous dorsal inserted opposite ventral, the first part of slender 

 spines, the second part apparently distinct, of rather strong rays; the 

 dorsal covering eleven vertebrae. 



Anal fin mostly obliterated, the insertion opposite that of the soft 

 dorsal. 



Twenty vertebras shown, twelve belonging to the abdominal region, 

 the total number probably twenty-six to thirty. Vertebrae rather small, 

 slender and longer than deep, the centrum deeply fluted with three or 

 four ridges on either side. Neural and haemal spines rather small, turned 

 backward and not strongly curved. 



Traces of small scales on the head. 



This fish is evidently one of the PERCOIDEI, and on the whole it 

 seems most likely to be one of the SCLENID.E. Its salient features are 

 the posterior insertion of the ventrals, the entire and probably cavernous 

 bones of the head, and the fluted vertebras.
