Shell elongately conical, rather plum]), spire conical not quite as long 
as aperture, whorls rather llattoned, sutures lightly impressed, last whorl 
two-thirds the length of the shell, mouth oval, elongate, lip Ihin, cohunella 
straight, reflected, hiding, but not closing, a de(i> narrow umbilicus. 
The coloralion is commonly unicolor, i)ah‘ fawn, sometimes with a sub- 
sutural reddish band and red longitudinal streaks bul never with a red cir- 
eumbilical patch. Dead shells are white as the coloration lies in a very fine 
periostraeum. 
The apex is rather flattened, of two whorls, the sculpture of fine punc- 
tuation or thimbling as it is sometimes termed, this being coarser than that 
of the Swan River bulla; the adidt sculiiture consists of radial growth lines, 
irregular and wavy, becoming less marked on the last whorl. On the early 
whorls there is a faint concentric sculpture also seen but this is never notable 
and usually vanishes early. Length 26 mm., breadth 15.5 mm. This de- 
scription is drawn up from apecimens from the type locality, where a groat 
deal of colour variation is not seen. As related below, many shells have hee.i 
regarded as answering to the original nominations, hut as now restricted the 
above apjtlies exactly. 
The confusion in connection with the common King George’s Sound 
shell has lasted since its discovery. A similar shell was found in the Perth 
district, and another not a great deal unlike at Shark Bay. Api)arently 
Ferussac distinguished these, and Lamarck confused them, and then Q'uoy
