Sept. 20th , 1934. By Bernard C. Cotton and F. K. God;try. 
C. blandiana Crosse 1864 ( Thalotia ). “Bland’s Canthari- 
dus.” Elevated conical, imperforate, solid, rather thick; longitud¬ 
inal striae, rather pronounced, numerous, oblique; spiral lirae, pro¬ 
jecting, spotted, and as though articulated with white and a 
purplish-violet, darker than the rest of the shell, of which the 
foundation colour is violet-rose; suture not distinct; whorls seven, 
flat; protoconch of one and a half turns, smooth, shining, pur¬ 
plish-violet with a whitish border; adult whorls striate, with six 
spiral lirae; last whorl angulated, slightly descending, nearly flat 
beneath, decussated by spiral cinguli and oblique striae; aperture 
slightly oblique, subquadrate; interior nacreous and near the lip, 
wrinkled; umbilical tract slightly concave near the columella; 
columellar margin arcuate, wrinkled, with one strong fold: basal 
margin wrinkled; outer lip thickened, granulate within. Height 
18.S, diam. 14 mm. (Type locality—Gulf St. Vincent). A tablet 
in the British Museum is labelled “Thalotia blandiana Crosse, 
S. Aust., C. F. Angas” and on the back “Thalotia blandiana ]. 
de Co. XII, 1864, S. Aust. Type, 70. 10. 26, 142.” Vcrco makes 
the following notes: “This is something like 7'. veglecta Tate but 
is rather narrow and has six rows of tubercles on the penultimate 
whorl and slightly curved rctrocurrent axial striae, subdist.ant, 
one to each tubercle, 1 have not seen it from South Australia.” 
As Angas suggested (P.Z. Soc., 1865, p.l89) this is probablv a 
deep water form. Possibly of C. neglectus. A single specimen 
from St. Francis Island (35 fathoms) conforms fairly well with 
the original description. A further specimen mounted by Ad¬ 
cock as this species from Salt Creek, Gulf St. Vincent, corres¬ 
ponds except that it has 7 spiral lirae instead of 6 and measures 
20 x 15 mm. 
C. abnomrs Crosse 1864. “The Abnormal Cantharidus.” 
Shell imperforate, subelevated conical, thick, rather solid, buffish- 
tawny, ornamented with spiral series of little beads (white and 
brown articulated) alternating with obsolete striae; suture little 
impressed; whorls 6, convexo-plane, the apical 2 whitish, smooth, 
the following articulate-cingulate, the last slightly descending, 
subcompressed, obsoletely angular; base slightly convex and like 
the upper surface in colour; aperture a little oblique, subquadrate, 
lirate within; columellar margin subarcuate, uniplicate, basal and 
-outer margins thickened, rugose within. Height 15, diam. 10 mm. 
(Crosse). (Type locality—Gulf St. Vincent. South Australia). 
Although x\dcock and Vcrco listed this species we have never 
seen specimens. Vcrco writes in his MS. notes: “This species 
lias not been recognised by any collectors in South Australia.” 
According to the description it is very closely allied to Callios- 
terna zietzi Yerco 1905 and we should be disposed to regard it 
as probably the beach form of that species.
