552 The Bass and their Relatives 
In certain species that swim more freely in deep waters, these 
fins are naked. Among them is the Arnillo, Apsilus dentatus, 
a pretty brown fish of the West Indies, and its analogue in 
Hawaii, A psilus brighamt, red, with golden cross-bands. Aprion 
virescens, the Uku of Hawaii, is a large fish of a greenish color 
and elongate body, widely diffused throughout Polynesia and 
one of the best of food-fishes. A related species is the red 
voraz (Aprion macrophthalmus) of the West Indies. 
Most beautiful of all the group are the species of Etelis, 
with the dorsal fin deeply divided and the head flattened above. 
These live in rather deep water about rocky reefs and are fiery 
red in color. Best known is the Cuban species, Ftelzs oculatus, 
the cachucho of the markets. Equally abundant and equally

beautiful are Etelis carbunculus of Polynesia, Etelis evurus of 
Hawaii, and other species of the Pacific islands. 
Verilus sordidus, the black escolar of Cuba, has the form 
of Etelis, but the flesh is very soft and the color violet-black, 
indicating its life in very deep water. Numerous small silvery 
snappers living near the shore along the coast of western Mexico 
belong to the genera called Nenichthys, Xenistius, and Xenocys. 
Xemstius californiensis is the commonest of these species, 
Xenocys jessi@, the largest in size, with black lines like a striped 
bass. To the genus Dentex belongs a large snapper-like fish of
