 much smaller size than any other species of Mycteroperca. 

 It is in many ways an aberrant form, showing affinities 

 With Iipinephel us. The anal fin is short, as in E^ine- 

 phelus, while the general appearance and coloration is 

 that of Mycteroperca. The structure of the skull shows 

 that its affinities are with the latter.
