38 FOSSIL FISHES OF LOMPOC 



Another example (No.. 220), 7% inches long, lacking the dorsal re- 

 gion, evidently belongs also to EVESTHES JORDANI. The anal fin is better 

 preserved, having apparently 38 rays, caudal large, rounded, 1% in 

 head, of about eighteen rays. Pectoral inserted high, about 2^4 in head, 

 ventral and scales obliterated. 



A well-preserved example, No. 510, is 10y 2 inches long. In this 

 specimen the three expanded, curved neural spines shown in E. HOOVERI 

 are plainly evident, though less marked than in the latter species. These 

 show faintly in No. 509, but cannot be made out on the original type. 



The vertebral column in No. 510 is not at all decurved anteriorly. 

 Anal rays definitely 42 ; vertebrae 32. Pectoral rays 16. 



The hypural plate in this specimen is strongly striate, made up of 

 many coalescent slender neurals and hsemals. This structure is oblit- 

 erated in the original type of the species. 



Still another example, with head and thoracic region only (No. 296), 

 shows the complete pectoral fin of about 13 rays, 2*4 in head. Eleven 

 dorsal vertebras well arched. The body cavity very short, 2*4 in head ; 

 maxillary half head. The fish was about as large as the others the part 

 preserved six inches long. 



Another specimen (No. 33) shows part of the head with twenty-one 

 vertebra;, the insertion of the anal being about under the tenth, the fins, 

 interneurals and interhaemals being all lost. 



No. 276 is a fragment of the same species. 



21. Evesthes hooveri Jordan, new species. 

 (Plate XXVI) 



Type No. 512, 9*4 inches long, in a fine state of preservation. Body 

 deep, the head 2% in length, the depth 1%, the anterior profile even. 

 Head blunt, as deep as long ; mouth rather large, very oblique, the maxil- 

 lary extending to below eye, 2% in head, being much shorter than in 

 EVESTHES JORDANI. Orbit about equal to snout, 5 in head; the imprint 

 being on the left side of the fossil, the eye was on the right side of the 

 fish. Interorbital ridge narrow, a somewhat elevated ridge. Vertebral 

 column not bent downward anteriorly, the vertebrae 35 in number. 

 Three of the anterior neural spines much expanded, curved and bent 

 forward, all the others slender, needle-like; interneurals all short, thin, 

 hair-like, placed at angles with the neurals and much more numerous, 

 2 to 4 in each interspace. 



Haemals much longer than neurals, the first three or four expanded 

 and joined to form a curve or "pelvic bone" about the belly, extending to
