types both of latipinnis and retropinnis are adult males, that supposition 

 is not tenable. 



So far as is known to me, but one genuine specimen of C. latipinnisis 

 now known. It is the original type of Baird and Girard's description,

 well represented in the figure referred to. This specimen now lies before 

 me, and the comparisons above made were taken from it.
