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. 



I think this is most likely only a variety of P. tenuis, 

 Gaskoin.

Pritchard and Gatliff make C. dictua and C. vincta 

 synonyms of C. 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 (Van Diemen Land) is suggestive, its 

 size 13 mm., though larger than the majority of examples, is 

 equalled by some C . 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 Dictua form, with its oblique w/ider 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.
