sharply curved fold. Type — Height 7, diam. 1.8 mm. Rottnest 
Isand W.A, (Reg. No. D10626 S. Aust. Mus.) Beach, Gulf St. 
Vincent, Port Lincoln, also dredged Cape Borda 55 fathoms. Pre- 
viously mistaken for S. jonesiana Tate, a Pleistocene fossil from 
the Tintinara bore, which is without sculpture. S. unisulcata is 
larger, and the periphery less rounded. Examples vary in width 
of sutural channel and convexity of the whorls. 
S. jonesiana Tate 1898 {Odontostomia) . “Jones’ Syrnola''’ 
Narrowly pyramidal, shining; white; smooth; w'horls eight, of 
moderately rapid increase, flat; base regularly convex; suture 
linear, well defined; mouth pyriform, with a stout elevated fold 
at the origin of the columella, inner front angle of mouth slightly 
effuse and thickened with a slightly reflexed edge. Height 6.25, 
diam. 2 mm. Type, a Pleistocene fossil from the Tintinara bore. 
The species is broader than S. tincta but differs in; its longer 
mouth and the far-backward position of the columella-fold; in 
its apertural characters it resembles S, infrasulcata which is, 
however, a robust shell, and has a sculptured body whorl. The 
description is given here, but we have not seen recent S.A. speci- 
mens conforming with it. Recent specimens in the S.A. Mus. 
identified as this species, appear to be worn S. unisulcata (see 
above). 
S. elliottae sp. nov. PL I, fig. 7. “Eliott’s Syrnola.” El- 
ongate oval, rather solid, shining, polished, translucent; white, 
with one brown band immediately above the suture in the spire 
whorls, running round the body whorl to the middle of the outer 
lip; axial growth striae, very fine, numerous; protoconch globose, 
mammillate, sinistral, smooth, oblique, of two turns; adult whorls 
eight, flatly convex; suture impressed; mouth pyriform; outer 
lip simple, thin; inner lip reflexed; columella with one fold curv- 
ing uninterruptedly into the basal lip. Type — Height 8, diam. 
2.3 mm. King George Sound W.A. 22-28 fathoms. (Reg. No. 
DJ0627 S. Aust. Mus.), Also Gulf St. Vincent, 1 specimen. More 
solid than S. bifasciata Tenison-Woods, and more pupaeform in 
the early whorls, profile is curved instead of straight; the columel- 
la fold curves into the basal lip, while that of S. bifasciata is 
somewhat straight and vertical here, with a second rudimentary 
fold. Named after Mrs. E. C. Elliott, a foundation member of 
the Shell Club, 1925, afterwards the Malacological Society of 
South Australia, and a painstaking collector on many Queensland, 
New South Wales, Tasmanian and particularly South Australian 
beaches.
