Hab. 
This species may be distinguished from the P. perversa 
by its stouter and broader growth, and by the orange red 
colouring of the columella. It grows to a larger size and 
I am not aware that it is ever found reversed.

Tur Parapisp Pyruta. Shell ovately pyriform, thick, 
solid, abbreviated and umbilicated at the base; 
whorls angulated round the upper part, sometimes 
concave and conspicuously nodose, spirally grooved 
at the base and above the angle; whitish or bright 
orange-yellow, encircled in the young shell with 
numerous narrow purple-brown bands.

Few species exhibit a wider variation of growth than 
the present, some examples being rounded and smooth at 
the top (properly speaking, the base) whilst others are 
strongly noduled. The difference in the style of painting 
appears rather to indicate a difference in age ; not that every 
specimen in an early stage of growth exhibits the bright 
purple brown bands represented at Fig. 17 a, but all that 
have this character are found of lighter growth, and traces 
of it may be observed in the rich orange yellow specimens 
of maturer age. 
Lamarck notices the circumstance of this shell being 
vulgarly called ‘The Orange-mouth Pear’, Poire a bouche 
orangée; it was, however, originally called the ‘ Pear of 
Paradise’, Poire du Paradis, Oranjiemondige Paradyspeer, 
and I think Martini’s name above quoted should certainly 
be retained..
