“Dredged in 7 fathoms, 1 alive; taken on Port Victor 
beach, typical; dredged in 9 fathoms, Port Lincoln, 1; and 
in Spencer Gulf, depth unrecorded, 3; taken on beach at 
Port MacDonnell, with an added peripheral narrow spiral 
line of white, dotted or continuous.

Pritchard and Gatliff make (. dictua and C. vincta 
synonyms of CU. nubeculata, though the locality of this species 
is unknown. Tate and May followed them, and for the sake 
of uniformity I have accepted the identity. I am, however, 
more disposed to think that C. saccharata, Reeve, might have 
priority; in publication it has priority in place in Conch. 
Icon., its locality (Yan Diemen Land) is suggestive, its 
size 13 mm., though larger than the majority of examples, is 
equalled by some CU. vincta, and it corresponds in description 
with the translucent pink or salmon-red varieties to which 
Pritchard and Gatliff refer. 
There are three typical colour varieties, if we exclude 
C. saccharata, Reeve, viz.:—the C. dictua form, the Vincta 
form, and a maculated form. 
The Dictwa form, with its oblique wider or narrower 
brown lines coalescing into long arrow-heads, may vary as 
follows :-—— : 
1. There may be a peripheral spiral of white spots. 
2. A peripheral spiral of articulated white-and-brown 
spots, and another infrasutural. 
3. An infrasutural spiral only of articulated white-and- 
brown spots.
