Some are uniformly light-brown, with a broad infra- 

 sutural band, well defined anteriorly, articulated blackish- 

 brown and white : the white areas may be the larger, or the 

 brown, or both may be very narrow and numerous, ^he 

 white areas may consist of white dots. In addition to the 

 infrasutural band there may be a very distinct narrow peri- 

 pheral articulated white-and-brown spiral line, its spots 

 varying much in length. The infrasutural white areas may 

 extend down to this line, the brown being of their usual 

 extent, or these may reach it as well. These areas may both 

 be continued from the suture obliquely to the extreme end of 

 the shell, and be united in a narrow brown area behind the 

 notch (P. xavieriana, T. Woods). In these last two variations 

 the brown may be more or less completely flecked with tiny 

 white dots. The shell may be uniformly light-brown, or very 

 light-brown or white, with a narrow brown-black line imme- 

 diately above the suture, and encircling the body-whorl, or 

 pure white. The shell may be very pale-brown, flecked all 

 over with white dots, and have two broad delicate purple 

 spiral bands, one just below the centre of the spire-whorls, the 

 other below the periphery of the body-whorl ; or there may 

 be an infrasutural narrow articulated band, then a light - 

 brown band, then the purple band, then a peripheral brown 

 band, then the basal purple band. This purple variety, 

 which is an exquisitely pretty shell, I call var. pur pur eo- 

 cincta. 



Taken along the whole of the South Australian coast- 

 line. Dredged alive in 9 and 12 fathoms Gulf St. Vincent; 

 15 fathoms Point Marsden ; dead in 17 fathoms Backstairs 

 Passage, several, and in 20 fathoms; in 25 fathoms Thorny 

 Passage, 2 fresh; in 40 fathoms off Beachport, 6 nearly 

 bleached ; none at greater depths. It is plainly a shallow- 

 water form.
