HELLER AND SNODGRASS 



light, barred with blackish ; spinous dorsal dark like back but be'- 

 coming lighter at tip; venlrals and pectorals light without darker 

 markings; anal fin dusky. 



All the specimens agree in proportions and coloration with the 

 type. The fins in most of the specimens are in poor condition. 



Allied to G. zebra^ which species it resembles in proportions, shape 

 and fin characters. This species apparently is marked with light 

 stripes where G. zebra^ possesses dark ones, the darker median stripes 

 in the light areas'being represented by the darker median stripe in the 

 dark stripes of the latter. The light stripes do not form reticulations 

 below the eye as do the dark stripes on G. zebra. The species differs 

 further in the more rounded dorsal profile of the head (which, in G. 

 zebra is considerably angulated and projecting before the eyes), in the 

 lower spinous dorsal, the shorter snout, the spotted head, and dark 

 barred dorsal and caudal fins. 



In the collection are specimens from Albemarle (Tagus Cove),Nar- 

 boro and Seymour Islands.
