EVESTHES JORDANI 

 A PRIMITIVE FLOUNDER 



FROM THE 



MIOCENE OF CALIFORNIA 



BY 



JAMES ZACCHAEUS GILBERT. 



INTRODUCTION. 



The specimen of fossil flounder here described as new was 

 obtained from the diatomaceous beds near Lompoc now being 

 commercially worked by the Magna Silica Company, of Los 

 Angeles, California ; and it was through the courtesy of George 

 B. Hanniman of that company that this specimen was obtained. 

 In these beds have been found several specimens of fishes, but 

 the most perfect is this one. This specimen is an imprint of 

 apparently a mature fish almost complete and very well defined. 



Preliminary notes with a plate were published in January, 

 1909, 1 but no name has hitherto been assigned. 



This species differs from all other flounders in the greater 

 development of the body-cavity, and from most of them in the 

 very large size of the mouth. The generic name Evesthes is 

 given because this flounder was a large-mouthed one and doubt- 

 less a voracious eater; and the specific name is proposed in honor 

 of Dr. David Starr Jordan, to whom I am much indebted for 

 his unstinted encouragement and valuable aid in the preparation
