FRESH AND BRACKISH WATER FISHES.

So we see there is a great difference in the proportion 

 of these measurements in one and the other. In both ani- 

 mals the upper half of the body is dark, the lower half light 

 brown , along the sides 5 black dots and 2 or 3 on the 

 back; the vertical fins are dotted. 



Sub N°. 5174 we possess 133 ex. from the East Indian 

 Archipelago , determined by Bleeker as G. celebicus C. V. 

 (after Day , p. 289 , G. celebicus syn. with G. biocellatus 

 C. v., but after Giinther it is syn. with G. giuris , which 

 is also my opinion). One of them , A , with a total length 

 of 118 mM., has the caudal fin 29 mM., the 2-1 highest 

 dorsal ray, with short filament, IS'/g mM. and the height 

 of the body 16 mM. 



Bottle N". 5175 contains 25 ex. from the East Indian 

 Archipelago , determined by Bleeker as G. giuris C. V. 

 Among them I found a specimen , B , with the following 

 measurements: total length 117 mM., caudal fin 29 mM., 

 2<i highest dorsal ray, with long filament, 22 mM., height 

 of the body 14 mM. 



The width of the interorbital space in A is 5 mM., in 

 B 272 mM., that of the head in A 18 mM., in B 13 

 mM. The enlarged teeth in both jaws are in B greater 

 than in A. 



Bottle N". 5176 contains 45 ex., also from East Indian 

 waters and determined by Bleeker as G. catebus C. V. The 

 following are some measurements of large specimens :
