 base, by a pearly-white band. The anal fin is scarlet towards 

 the front and yellowish behind. The ventral fins are 

 hyaline with the outer rays golden. The pectoral fins are 

 reddish, with a small dark blue spot inside, at the base. 

 In each eye, the iris is a beautiful orange tint.

 in which the female has assumed the livery of the male, or 

 vice versa, are not uncommon. I have found this to be 



* I never yet saw a young " Blue " Groper that was blue, the ground 

 colour being always a reddish-brown.
