same, the only distinction being several dark stripes running obliquely from the 
back toward the central fins, which are not observable in the tunny. Its flesh is 
little used. 
The Dolphin ( Coryphcena hippurus ) is a frequent sight in tropical waters. 
It is about five feet in length, and has a yellowish body, with a black back, 
both body and back being spotted. It is often called the golden mackerel , and 
is not to be confounded with the cetacean dolphin. It is strikingly lustrous, 
but the iridescence of the

the water speedily under¬

The Thread Fish,

The Fly Shooter ( CJielmon rostratus ), found in Indian waters, is insecti¬ 
vorous, and as a bean-shooter rivals the most expert small boy. Upon discov¬ 
ering an insect it will shoot it with a drop of water ejected from its snout, and 
its precision of aim would put to the blush a Robin Hood of England. A species 
found in Java ( Toxotes jaculator) can shoot successfully at the distance of three
