"An extremely critical form. E. A. Smith considers it a variety 

 of P. porphyrostomus ; Layard, on account of the columellar fold, a 

 P. mariei. From the general form and peculiar coloration of the 

 parietal wall, I can only place it in the immediate vicinity of P. pseu- 

 docaledonicus" (Kobelt).
