1002 MR, C. TATE REGAN ON 



a lateral series of short vertical bars ; usually a blackish spot 

 above origin of anal fin. 



c? . Dorsal origin nearly equidistant from eye and base of 

 caudal. Bars on side well marked ; lateral spot indistinct ; a 

 blackish streak behind first produced ray of anal. 



Here described from several specimens up to 75 mm. in total 

 length from Oaba,, including a male of 47 mm. extremely similar 

 to the type of G. torralhasi, and co-types of G.falcatus. The last 

 is a pale variety without the lateral spot, but structurally similar 

 to G. miinotatus \ the slight production of the vertical fins is 

 found in several specimens with the typical coloration.
