to Hindostan; Dormitator maculatus, the stout-hodied guavina- 
mapo of the West Indian regions, with the form of a small 
carp. Guavina guavina of Cuba is another species of this type, 
and numerous other species having separate ventrals are found 
in the East Indies, the West Indies, and in the islands of Poly- 
nesia. Some species, as Valenciennesia strigata of the East

Indies and Vireosa hane of Japan, are very gracefully colored. 
One genus, Eviota, is composed of numerous species, all minute, 
less than an inch in length. These abound in the crevices in 
coral-heads. LEviota epiphanes is found in Hawaii, the others 
farther south. Hypseleotris guntheri, of the rivers and springs 
of Polynesia, swims freely in the water, like a minnow, never 
hugging the bottom as usual among gobies.
