and at a considerable distance from the tail. The number of 
rays in the former has been counted as from five to seven, 
and those of the last-named fin one or two less. Mr. Thompson 
had counted only three, but he supposes the fin to have been 
injured. When viewed obliquely an obscure tabular process 
was observed in front of each eye; but this could not be 
discerned except when the fish was alive in the water; obviously, 
however, their absence ought not to be made a portion of the 
specific character. 
The colour of different examples varies considerably. Thus 
in one it was light brown, with a number of dots of cserulean 
blue between the eyes, and others of smaller size extending half 
way back to the tail; colour of the pectorals pale pink. No 
more than eight rays were counted in the tail; which is the 
more remarkable, as Mr. Thompson assigns to this organ twelve 
and thirteen, and Mr. Yarrell ten. The name of this species 
has been assigned to it from two remarkable and beautiful spots 
which adorn the sides, one on each, near the pectoral fin; but 
they frequently are not to be seen, without regard to the size 
of the fish; and I have never been able to perceive them in 
examples obtained close to the shore.
