2. CRENILABRTTS. 85 



This species may be easUy distinguished from its nearest ally, C. 

 quinq\t,emaeulatus, by the larger scales on the check, and by the 

 greater number of longitudinal series of scales above the lateral line. 

 The characters by which the two species have been distinguished 

 are constant in all the specimens examined ; the anterior spot on the 

 dorsal fin is the most distinct, whUst the others are paler and may 

 entirely disappear with age. The number of the anal rays has been 

 incorrectly given by Valenciennes.
