Man's Hat, on the inner North Head of Port Jackson. The 

 squamately ribbed depressed species of Mr. Reeve and Mr. An^as, 

 are only the young and depressed species of aculeata of still xavy 

 young specimens. Many hundred species might be invented from 

 examples selected from the rocks all along the coast of New South 

 Wales

 Hob. — Outer Manly Beach, Newcastle, Port Stephens, Manning, 

 Macleay, and Narubuccra Rivers, Port Macquarie, Bellinger, 

 Clarence, and Richmond Rivers, found on all beaches near the 

 mouths of the above rivers and ports. Victoria and South 

 Australia. 



This very fine and well-known species was first described by 

 Philippi in the Proceedings of the Zoological Society of London, 

 1851, and well figured in 1852, by Philippi in Martini and 

 Chemnitz, second edition by Kiister ; then Reeve in 1855, gives 

 it a new name as Inci, species 89. At species 37, he finds 

 another large specimen in the Cumingian collection from South 

 Australia, and being a little more conical than the Incei of 

 Philippi, found on the east coast of Australia, Mr. Reeve, pen 

 in hand, describes, figures and names it Baconi, only, I believe, 

 to gratify Mr. Cuming. At species 130, in Reeve's Conch. 

 Icon., he also figures the small form under another name as fibula, 

 this is the most common form found on the beaches near the 

 Bellinger River Heads, on sandy mud, well up from the sea break. 

 The large specimens are found on the sand flats, close to the sea 

 break. The extensive series that I have from all the above 

 localities, convinces me that they are all of one species.
