others. The caudal is long, rounded, and formed of fourteen 
long rays and of several others on each side almost as long ; the 
anal is as high as the body, of one spine and ten rays ; pectorals 
two-thirds as long as the head, and of eighteen rays. 
The body is of a light olive green, with the lower parts of a 
blueish white ; the head almost entirely black in the adult ; the 
edge of the scales is rather obscure ; the dorsals are generally 
green ; the first has sometimes two series of reddish spots, and 
sometimes it is white, with two longitudinal broad bands, more 
or less carmine, the coloured part being covered with very minute 
black dots. The second dorsal has three or four longitudinal 
series of red dots, which sometimes unite, and form longitudinal 
bands. The caudal has numerous transverse series of small, red 
spots ; the ventrals and anal white ; eye gilt. 
The young specimens have the head less inflated. 
This fish is very common in the lower Yarra ; they are very 
voracious, and have often in their broad mouth, and partly digested, 
fishes as large as themselves, and generally of their own species. 
Sometimes pieces of wood are found in the same way, and held 
fast by their teeth. 
Mr. Krefft has described, in the “ Proceedings of the Zoolo- 
gicial Society,” ISGd, p. 183, four Australian sorts of Eleotris, 
one of which (E. Grandice-ps) may he this. There is one ray less 
at the second dorsal and at the anal, but this may depend on the 
different ways of counting the last one. It is from the Clarence 
River. The principal reason for not uniting my sort with his 
is, that he says, — that the pectorals attain the base of the anal ; 
while in my specimens they do not.
