716. C. sueuri Cuv. & Val. 



This species appears to differ from the preceding in the increased num- 

 ber of tin rays. The elevated crest represented in DeKay's figure of his 

 " C. globiceps " is a character of very old individuals. " D. 64 ; A. 20." 

 ( Cuv. & Val.) " D. 63; A. 29." (DeKay.) Atlantic coasts of the United 

 States; rare.
