The general tint a pale flesh colour with spots and patches 

 of carmine about the upper and under surface of the jaws, 

 around the eyes, on the top of the head, sides of the body 

 and abdomen. The description was taken from the largest 

 of five specimens, on three of which the spots behind the 

 eyes were conspicuous, but wanting in the other two. 



The appearance of the surface of the disk is shown in the 

 woodcuts of some of the more closely allied species, to assist 

 in determining specific distinction. 



The vignette below represents a man fishing for prawns on 

 a rocky coast. The fisherman deposits around him eight or 

 ten hoop-nets, each baited with a piece of stale fish : a large 

 bung by way of a buoy is attached to each hoop. The man, 

 with a long forked stick raises the nets in succession, by 

 putting the fork of the stick under the bung, and deposits 

 them again after examination.
