B. The flames may be wavy, with several curves in their 

 total length . 



C. With the axial flames there may be a white spiral 

 band beneath the suture, a peripheral spiral of white spots, 

 and a white spiral just above the revtlving lirse over the 

 canal. 



D. The flames may be absent and only the three white 

 spirals may remain. 



E. Or the lower two only. 



F. Or only that above the notch. 



G. Or the shell may be wholly white and unornamented. 

 A third series consists of shells of a cinnamon-brown 



tint, or bluish or purplish-white. It is squat in shape, with 

 convex-whorls slightly tumid below the suture, with a blackish- 

 purple apex. 



A. The body- whorl is ornamented throughout with three 

 spiral rows of arrow-heads directed forwards, and formed of 

 dark-brown rather close- set lines; the three rows are separ- 

 ated along two narrow spiral lines, one just above the peri- 

 phery and the other from the back part of the aperture. 



B. The arrow-head markings may be absent, the shell 

 being otherwise indistinguishable. 



A fourth series has two broad pale-pink spirals on the 

 body-whorl ; sometimes the upper one is broken up into large 

 square blotches. The upper band is defined below by a 

 narrow spiral line of white spots; these may be narrow, 

 transversely elongate, placed obliquely, with the anterior end 

 slightly higher than the posterior, or club-shaped, with the 

 wider end in front ; sometimes from the narrow end of these 

 clubs directed downwards and backwards, a narrow long 

 white spot may extend downwards and forwards. 



Taken on the beach all along the coast from Beachport 

 ■to St. Francis Island. Dredged in Gulf St. Vincent and 

 Spencer Gulf, many alive and dead ; in 40 fathoms off Beach- 

 port, 36, some alive ; 45 fathoms off Neptune Island, 1 

 poor; 55 fathoms off Cape Borda, 25 good, 2 poor; 90 

 fathoms off Cape Jaffa, 1 ; 110 fathoms off Beachport, 2 good, 

 37 poor ; 130 fathoms off Cape Jaffa, 15 very poor ; 150 

 fathoms off Beachport, 1 poor. This species extends out into 

 quite deep water.

 Shell small, solid, of five whorls, including a blunt pro- 

 toconch of two round smooth whorls ending abruptly. Suture 

 linear, distinct, ascending at the aperture. Spire-whorls con- 

 vex below the suture; the first two sloping towards the lower 

 suture j the third somewhat contracted. Body-whorl large
