P. harherinus superficially resembles macronemus but the dark spot 

 on the peduncle is much larger and located at the midbase of the 

 caudal fin rather than dorsolaterally on the caudal peduncle. The 

 characters given by Smith (Sea fishes of southern Africa, p. 229, 1949)

 last rays of the soft dorsal and anal fins, is completely erroneous for 

 this condition represents an age character in both species. His illu- 

 stration of macronemus (fig. 565), lacks detail and accuracy in the 

 size and location of the caudal spot.
