a little shorter than eye, which is 31 to a little more than 4 times in 

 length of head ; interorbital width 2 J to 2| times in length of head ; 

 jaws equal in front ; mouth extending to below anterior margin or 

 anterior fourth of eye. Gill-rakers short, 8 on lower part of anterior 

 arch. 



Dorsal iii-iv 8-9 ; originating well behind middle of body, about 1^ 

 to 1| times as distant from occiput as from base of caudal. Pectoral 

 I to f length of head or of the distance from its base to ventral. 

 Ventral 6-rayed, about equally distant from end of snout and base of 

 caudal. Anal iv 8-9, originating below anterior third of dorsal. 

 Caudal rounded sub-truncate, continued anteriorly on caudal peduncle, 

 which is nearly twice as long as deep. 



Colour (of preserved spcjimens) brownish, minutely speckled with 

 dark specks and with faint dark bars on back and sides. 



Many specimens, ranging from 23-42 mm. in length, from George 

 River, Cape Province. 



This little fish closely resembles G. zebratiis, but the dorsal fin is 

 placed decidedly further back, and the anal rays are more in number. 

 It is not improbable that the three species described may on examina- 

 tion of more extensive collections prove to be merely varieties of one 

 species.
