Dredged in 100 fathoms 90 miles west of Eucla, 4 ; in 

 75 to 120 fathoms 120 miles west of Eucla, 1 ; in 95 fathoms 

 90 miles west of Eucla, 3. All were well coronated, with 

 moderately exserted spires and with more or less marked axial 

 plicae on the inflation of the body- whorl, a little below the 

 coronation. The colour when fresh was a pink-flesh tint, 

 with a blackish-purple on the varix of the canal, and about 

 seven blotches of black-purple on the outside of the recurved 

 labrum, fading away towards the dorsum as vanishing spiral 

 flames. Some have two spiral bands of orange blotches on the 

 body- whorl. 



One quite fresh shell was taken in 140 fathoms, 34 mm. 

 22*5 mm., without angle or tubercles or plicae, with a thick- 

 ened reflected lip, with seven purplish-black spots on it, a 

 micromorph of the variety found to the east of Bass Straits.
