The Melampi are strictly amphibious, some of them living 

 in clear salt water, at about the depth of a fathom, while 

 others are inhabitants of Mangrove-swamps and the muddy 

 banks near the mouths of rivers. West Columbia, the 

 Sandwich Islands, and the West Indies appear to harbour 

 numerous species of this genus, which, however, is likewise 

 represented in Africa, Madagascar, the Philippines, South 

 America, and New Zealand.
