30 FISHES OF NEW ZEALAND, 



Common in rivers and lakes. 



This species is exceedingly variable in the size of the eye, the size 

 and shape of the interorbital space, and in the colors, being sometimes 

 washed with yellow and sometimes entu'ely black. At first sight it 

 would appear that at least three sjiecies could be made out, but after a 

 careful examination of a large number of specimens from many parts of 

 the country, I can find no constant distinction between them, some 

 specimens exliibiting intermediate charactei*s, connecting others which 

 appear to be quite distinct. The proportion between the diameter of 

 the eye to the interorbital space varies from one to one half. Of Eleotris 

 radiata there appears to be no description ; it is said to have been taken 

 at the mouth of the river Thames,
