Das Vierauge. 
Bloch ichth. t. 361 . 
The fish represented on the present plate is dis¬ 
tinguished by a highly remarkable particularity in 
its conformation ; the eyes appearing as if double. 
This however, on accurate dissection, is found to be 
owinor to an internal division of the cornea, in such 
a manner as to present the appearance of two pupils 
in each eye; a circumstance well explained in the 
work of Dr. Bloch. The A. tetropthalmus is a na¬ 
tive of the American seas, and measures about twelve 
inches in length.
