overlap of the wliorls sliows a false mai'gin to the suture. Colour 

 clear hazel. Whorls five, the upper very convex, the summit 

 rather protuberant, the body-whorl flattened. Surface very 

 smooth and glossy, in fresli specimens, but appears, in weathered 

 examples, especially on the penultimate whorl, to be finely, 

 obliquely striated. Aperture circular, lip thickened, canals pro- 

 tected by triangular tongues, as in P. strangei. Height, 6; 

 breadth, 3 mm. 



This species is like P. strangei, and may have been confused 

 with it. But it has a different geographical distribution, is 

 larger, broader in proportion, and less upright. For effective 

 contrast, the drawings of the two here gi\en are of the same 

 magnificatioji. 



Mr. Jackson found it associated witii P. robiista Cox, in 

 August, 1908, under leaves, on the ground, in the Bottle-tree- 

 scrub, west of Gladstone, Port Curtis.
