‘two whorls a fifth small cord appears above the suture. The 
base is flatly rounded, with five flat low spiral cords. The 
‘aperture is squarely round, slightly effuse near the columella, 
> which is curved; inner lip, a broad glaze; outer lip simple, 
smooth inside, corrugated outside by the spirals, with a deep 
broad sinus well rounded at its depth between the two smaller 
‘cords; growth lines corresponding in outline with the outer 
lip constitute the only other sculpture. It has a pale-yellow- 
brown tint, with darker brown spirals between the cords, and 
sa broad brownish spiral over the middle of the base. 
Dim.—Length, 17 mm.; breadth, 6 mm. 
Locality.—Type in 110 fathoms off Beachport, with 11 
‘others good; in 150 fathoms, 8 poor; in 130 fathoms off Cape 
Jaffa, 9 good. 
It may reach 22°5 mm. in length. The suprasutural and 
infrasutural cords may each split in the later whorls at its upper 
part to form a small secondary spiral. 
Diagnosis.—Its alliance is with 7’. australis, Lam., from 
which, however, it differs in its more numerous and non- 
tuberculate spirals; from the Tasmanian variant, 7. granu- 
lifera, Tenison-Woods, it differs in the absence of nodulation, 
and the relative disposition of the ribs, and of numerous spiral 
threadlets. It is of interest to note that neither of these 
forms is found in South Australian waters, though taken at 
Western Port, Victoria, and in Tasmania abundantly.
