on the top, and another below, at the lower jaw: there is a very broad black line, 
which runs between the belly fins and the back, and divides the body tranfverfely into 
two parts; and at the anterior part of this there is on each fide a narrow, crooked, 
tranfverfe line; there is, behind this black line, a broad, tranfverfe, white one, which 
again divides the body; and below this there is alfo another broad, tranfverfe, black 
line : about the beginning of the tail there is another white line; and, finally, the 
tail itfeif is variegated in the fame manner : there is, near the bafe, a broad, flraight, 
black line, and farther toward the extremity, a broad lunated one ; and, finally, the 
extremity of the tail itfeif is white. 
The back fin is very tall in the anterior part, but in the hinder part it is low; it has 
forty-fix rays, of which the feven anterior ones are prickly, but two of them much
