OZYMANDIAS 37 



It is not certain that this specimen belongs to OZYMANDIAS, nor is it 

 clear in what family it should be placed. The vertebrae and interneural 

 structures agree very closely with those of the living genus OPHIODON 

 Girard (O. ELONGATUS), which now inhabits California waters. This is 

 the sole representative of its family among recent fishes. 



Family PLEURONECTID^ 



Evesthes J. Z. Gilbert (1910). 

 (Type: EVESTHES JORDANI Gilbert.) 



A genus of flounders, allied to HIPPOGLOSSINA Steindachner and 

 EOPSETTA Jordan and Goss, with fewer vertebras than HIPPOGLOSSOIDES 

 and smaller and more oblique mouth. 



Eyes normally on the right side ; mouth rather large and very oblique ; 

 body deep, compressed, the depth about half the length. Vertebrae 32 to 

 36, three of the anterior ones having very large, expanded neural spines 

 curved forwards ; dorsal rays slender, about 65 to 80 in number. Ventral 

 fins far behind eye ; hypural plate of many united slender neural and 

 haemal spines, its disk strongly striate. 



20. Evesthes jordani Gilbert. 

 (Plate XXIV) 



A fine example (No. 509), &y% inches long. Body short and deep, 

 with short body cavity and very large head. Head 2% in length ; depth 

 2 to base of caudal ; mouth very large, the jaws equal, straight, the max- 

 illary 1% in head; lower jaw with strong, sharp teeth subequal, well 

 spaced, seemingly in a single row. Vertebrae rather small, more elongate 

 posteriorly, the number 10 -f- 22 = 32 ; hypural plate strong ; anterior 

 neurals directed somewhat forward ; posterior more backward ; inter- 

 haemals all double, about as long as haemals, two to each haemal spine, and 

 attached to its tip. Vertebral column anteriorly bowed downward, more 

 than in type of E. JORDANI. Interhaemals slender, two to each neural, 

 as usual among flounders. 



Eyes probably on the left side, there being no trace of them in the im- 

 print, which is that of the right side ; dorsal fin beginning over the eye, 

 the fin low anteriorly, becoming higher behind. Body region very short, 

 21/0 in head, the anal beginning almost under front. 



This specimen is without doubt identical with EVESTHES JORDANI, de- 

 scribed some years since, from Lompoc, by Dr. J. Z. Gilbert. The genus 

 EVESTHES, as Mr. C. L. Hubbs has shown, is not far from the living genus 

 HIPPOGLOSSINA Steindachner of tropical America. The downward curv- 

 ing of the anterior vertebrae is characteristic of both.
