IV. Esox Ohioensis.— Kirtland, 



From a very perfect stucco cast and a dessicaled head of 

 a specimen taken in the Mahoning, a tributary oJ tlie Ohio 

 river, it is evident that this species is distinct from any of 

 the preceding. Its contour is more regular oval and ellip- 

 tical than that of the E. estor and less regular than 

 that of the E. nohilis. The head is rather small, fusiform 

 and attenuated, and its vertical measurement through the 

 eye proportionably less than in any other species. Caudal 

 fin emarginate and falcate more acutely than the Estor. 

 The color of the back, greenish brown ; sides lighter, but 

 shaded with brown; underneath white. 



Total length 30 inches; head 7|; vertical line through 

 the eye, from frontal surface to bottom of lower jaw, 2| 

 inches. This species sometimes attains 31^ pounds weight.
