The former are represented in British waters by four species, one of which, the Miller's-thumb, inhabits fresh-water. The . , marine species include the Sea- scorpion and Father-lasher. The Bull-heads on the Indian and Australian coasts are represented by the closely allied Flat-heads, or Crocodile- fishes, in which the head, as its name implies, is much depressed, and fully armed with spines, which are highly poisonous, and cause a violent irritation. These fishes live in shallow water, lying on the bottom, with which their colours harmonize so com- pletely that they are practically invisible.
