This and the preceding species have been united into one by some authors ; but we 
entertain doubts as to the propriety of doing so. All the specimens with three 
ocellated spots on each side (P. hexophthalma) have about ten narrow oblique brown 
lines radiating from the lower part of the eye, over the opercles, whilst the specimens 
with six or seven ocelli on each side (P. polyophthalma) have the sides of the head 
dotted. Unfortunately the internal organs of our specimens are not sufficiently well 
preserved to enable us to determine the sexes, so as to ascertain whether the differences 
between them are sexual.
