218. Cynoscion prsedatorius {Jordan d- Gilbert). 



Occasionally coming into the market in considerable numbers, reaching a 

 length of 75 to 110 cm. It is strongly distinguished from all other species of Cijnos- 

 cion by its more oblique mouth and heavier mandible. As this character seems to us 

 insufficient to warrant generic separation, we do not recognize the nominal genus 

 BuGCone based upon it. 



In twelve specimens, three have 18 dorsal rays, seven have 19 rays, one speci- 

 men has 20 rays, and one but 15. The last-mentioned seems normal in every way. 

 There is no distinct sheath at the base of the soft dorsal. The anal fin contains 2 

 spines (not 1, as described) and 9 rays. 



The scales above the lateral line increase in size posteriorly to below the mid- 

 dle of the soft dorsal, and decrease somewhat on the very slender caudal peduncle. 

 There are 65 to 70 oblique rows running downward and»i)ackward. The posterior 

 nostril is obovate in shape. 



219. Cynoscion squamipinnis (Gilnther). 



Not rare in the Bay of Panama. 



As stated by Steindachner, the scales along the lateral line are decidedly 

 larger than the others. There are 47 to 50 of these enlarged scales, and an equal 

 number of oblique rows of scales I'unning downward and backward above the lateral
