ocellus at base of caudal iniinediately above lateral line; the indistinct clouded

Eight specimens, part of No. 05918, 1 to I2 inches long from Fakarava, 

 Paumotu Islands, M. C. Z. 29524 (4 specimens). 



Description of largest specimen : Dorsal VI, 11; anal 10; head 3.36 in body; 

 depth 2.61; depth of head in head .9; eye 4.75; maxillary reaching very 

 slightly, if any, beyond a line from front margin of orbit, not from the pupil; 

 body strongly compressed ; profile rounded. 



Colors, dark brown with lighter head and breast somewhat darker fins. 



These specimens have the general shape of G. atrangulatus but with a smaller 

 mouth; they also have the general shape of Giinther's figure in Fische der Siidsee

 they agree better with the description in Cuvier & Valenciennes of G. histrio 

 than with any other described species, excejjt that there are no tubercles on the 

 head; since, however, these specimens do not now agree in color, we provisionally 

 refer them to G. histrio.
