34 FOSSIL FISHES OF LOMPOC 



base ; interhaemals small, except the second, which is much enlarged, bear- 

 ing the very long, curved second anal spine, the length of which is greater 

 than depth of body above it. 



Head large; body oblong; the back scarcely elevated; mouth rather 

 large, with sharp, even teeth ; vertebrae 24 or 25, small, deeper than long, 

 each with a median groove; neural and haemal spines moderate; inter- 

 neurals simple, straight, not much dilated, those under soft dorsal smaller ; 

 interhaemals, except the second, weak, oblique. Dorsal continuous, rather 

 low, deeply notched, the rays about XII, I, 13. The spines strong, the 

 longest spine not longer than those next to ft, and not double length of 

 next-to-last spine; last spine as long as soft rays, which taper rapidly 

 backward. Dorsal apparently XII, I, 3 or 4, I, 14 ; the soft rays not to be 

 counted; anal rays III, 7, the number uncertain. Caudal not forked; ven- 

 trals and pectorals detached and broken. 



No. 246. Body with broken head, 9 inches long. Vertebrae apparent- 

 ly 25'; depth about 5 ; head about 3 1 / 4 in length, bones all entire, neurals 

 and haemals meeting them at an angle, and mostly not so long. Second 

 interhaemals very long and strong; interneurals all simple, not at all ex- 

 panded at base, those behind quite slender. Dorsal spines XIII, the first 

 small one, third highest 1% in depth ; fin notched, the rays XII, I, 13 or 14. 

 Anal mostly lost, its second spine enlarged, its oblique interhsemal 4 depth 

 of body. Caudal truncate, mesially divided, the number of soft rays 

 about 16. This specimen is finely preserved. 



17. Rixator ineziae Jordan, new species. 

 (Plate XXII, fig. 2) 



Some of our specimens of RIXATOR seem to differ from the type. In 

 R. PORTEOUSI, the anal, as in SEBASTODES, is inserted posteriorly, its first 

 spine about under middle of soft dorsal, the second spine usually extend- 

 ing beyond the soft dorsal rays ; the body is slender, the depth at front 

 of anal about equal to longest dorsal spine. In the other form, which 

 I may call RIXATOR INEZLE, the anal is inserted about under front of soft 

 dorsal, as in nearly all the other SEBASTINE fishes, its long spine not ex- 

 tending beyond dorsal, and the depth of body at front of anal more than 

 longest dorsal spine, these spines rather higher than in R. PORTEOUSI. 



Type No. 45B, 7 l / 2 inches long, the body without head, the whole fish 

 about 9 inches, the counterpart, 45A, similar but fractured. Depth \% in 

 distance from front of anal to caudal ; about 3% in distance from snout to 

 base of caudal. Vertebrae 10 + 14 = 24, constricted, about as deep as 

 long, with a median groove ; neural and haemal spines moderate, straight ; 

 interneurals simple, slender, but apparently expanded at base. 



Dorsal fin continuous, XII, I, 14, deeply notched, the spines high, 

 slender, stiff; 13 present (12 in the duplicate), these much higher than
