South Australian Shells. 
S.A. NAT., VOL. XVI. 
Dec. 15 , 1934 
growth striae microscopic, sharp; body whorl subangulate at 
periphery; outer lip thin, acute, inside green, beautifully irides- 
cent; columella arcuate, not dentate, pearly edged; umbilico- 
columellar area vivid pea-green. Height 15, diam. 18 mm. 
Littoral, on short weeds in pools, not so common as the preceding,. 
Beachport to Port Lincoln. Not recorded from Western Austra- 
lia.. (Type locality — Gulf St. Vincent, South Australia). When 
very small the shells are umbilicate, and must not be confused 
with Austrocochlea concamerata Wood, which is constantly im- 
perforate. 
A. zeus Fischer 1874 (Trochus ) . ‘"The Dory Austrococh- 
lea. ” Imperforate, thick, obtuse; white with radiating flexuous- 
red lines; protoconch short, papillose, yellowish: whorls four to 
five, moderately convex, obliquely striate, spirally sulcate, suture 
impressed; last whorl ample, rounded, obsoletely angulated above, 
marginated at the suture; base convex; aperture circular, colu- 
mella subdentate at base; columellar callus thick, whitish-green; 
outer lip thick. Height 16, diam. 19 mm. Geraldton and Irwin 
River (Western Australia). We understand that this species 
was described by Fischer from several specimens of unknown 
origin, all of the same form and colour pattern. It appears to 
be closely allied to the South Australian A. adelaidae Philippi.

“COMBING THE SOUTHERN SEAS.” 
Written by the late Sir Joseph Cooke Yerco, M.D. (Lond.), 
F.R.C.S. (Eng.). 
(Edited by Bernard C. Cotton, Conchologist S.A. Museum) 
The book (now in press) describes the author’s unique 
adventures in dredging for Marine Specimens in Southern Aus 
tralian waters. Sir Joseph Yerco, 20 years Hon. Conchologist 
at the S.A. Museum, was the first to undertake extensive scien- 
tific investigations of our Southern Australian Seas. There are 
numerous illustrations, including colour plate, about 125 pen and 
ink drawing, and half-tones. A reprint of the rare, privately 
published “Catalogue of Marine Mollusca of South Australia” 
1908, is included. It is hoped the book will appear about 
December 17th. 
The price is 12/6, postage 7d., and orders may be placed
