November, 1932 . Bernard 
C. Cotton and F. K. Godfrey. 
Loay Island, Bohol, sixty fathoms in clayey sand; macleayana, 
Long Bay, Tasmania). A small aclcular species with the ribs 
wide apart and the interstices plain. Distinguished by the very 
Slender, turreted, habit. 
T. beddomei Petterd 1884 (Chemnitzia) (-T. scalarina 
J>rarier 1894: = T. cremiHfera Tate 1892). “Beddome's Tur- 
boniHa."* Elongatcly turrctcd, shining; milky -white, opaque; 
axial ribs, small, the interstices equalling the ribs in width; 
ribs obsolete at base of last whorl; whorls eight rounded; 
suture very much impressed; mouth oval: outer lip 
thin. Height 5, diani. 1.5 mm. Ccncral, all round the South 
Australian coast, but not common, beach and down to 55 fathoms. 
(Type locality — North West Coast, Tasmania). Some taken 
alive are purple stained. 
T. brevis Pritchard & Gatliff 1900 “The Short Turbonilia.” 
Very small, pupaeform; white; axial riblets, fine, close, about 
sixteen to twenty, with fine spiral threads in the interstices, giving 
rise to a clathrate ornament; the sculpture not always well 
marked on the body whorl; protoconch sinistral, smooth, of one- 
and-a-half turns, with immersed tip; adult whorls four or five, 
flattish or slightly convex, very gradually increasing in size; 
suture is well and somewhat suddenly impressed, imparting to 
the whorls a rather more convex appearance at the suture; mouth 
oval; outer lip thin, and alter ascending descends slightly before 
joining the penultimate whorl Height 2, diam. ,75 mm. Beach — 
Port Willunga, Wauraltie, Streaky Bay, Fowler Bay, uncommon;, 
dredged — Gulf St. Vincent, Cape Borda down to 55 fathoms. 
(Type locality — Rhyll, Phillip Island, Western Port, Victoria, 
from shell sand dredged from about 4 fathoms). Appears most 
like T. scalarina Brazier a Sydney shell, but is apparently more 
robust for its size, of fewer whorls, with distinct ornament in the 
interstices, and with more numerous ribs which run straighter 
up the shell. Shells in the S.A, Museum identified as T. brevis 
indicate that the protoconch is usually nearly horizontal, but 
some, apparently the same species, have the protoconch immersed. 
T. hofmam Angas 1877 (= T. nitida Angas 1867, preocc) 
“Hofmanns Turbonilla.” Sharply tapering, lurreted, rather thin, 
■hining; white; axial ribs, prominent, rather broad, interstices 
smooth, narrow; ribs abruptly ceasing at the periphery of last 
\vhorl; whorls thirteen, slightly convex; sutures impressed; mouth 
small, subquadrate; outer lip thin, a little produced below; colu- 
mella straight. Height 10, diam. 2 mm. Beach, Harwicke Bay, 
not common. Dredged, Rapid Head, Yankalilla Bay, Gulf St. 
Vincent, Backstairs Pasage, Investigator Strait, Middleton, to
