dextral, instead of sinistral, as described by Wright, the spire im- 

 mersed, forming a false umbilicus. Von Martens suggests that it is> 

 a distorted Turbo. Compare the sculpture with that of Turbo cor- 

 nutus.

This form I inadvertently placed in the synomymy of P. variegata 

 Lam. (p. 179). It seems to be quite distinct from that species. I 

 translate Philippi's description, which applies perfectly to the speci- 

 mens before me. 



" Shell ovate-oblong, conoid, very thin, very smooth and shining, 

 olivaceous, sometimes varied by narrow milk-white fiammules marked 

 with transverse red lines articulated with white dots ; aperture ovate, 

 longer than the spire. 



"The shell is long-oval, conoidal, thin, very smooth and very 

 shining. The whorls seven in number, are moderately convex The

 whorls are milk-white, and form a blunt apex. The aperature is 

 rather broadly ovate. The color is olive-brown, verging on red, 

 sometimes with narrow milk-white flammules, always with evenly 

 spaced red spiral lines, which are regularly interrupted by milk-
