Obs. A specimen of thi.s species, with a portion of the body-whorl wanting, was 
presented to the British Museum by the late Mr. R. Daintree, and was said to have 
been collected in “ Australia.” The section Placostyliis has not hitherto been observed on 
the Australian Continent, although known from many of the Pacific Islands, and the fossil 
must therefore remain doubtfully associated with its former fauna. An error may 
have been committed, but as Mr. Daintree was known to be a careful collector and keen 
observer, the species is pro-visionally included amongst the latter. The specimen retains 
the coarsely rugate appearance of B. Jibrattis, and is preserved in a fine ochre-yellow 
sandy matrix.

Obs. The late Mr. Gerard Krefft appears to have been the first to call attention 
to the fossil remains of this very remarkable genus. In a short communication 
forwarded to “ Nature” he recorded the discovery of the left upper dental plate of a 
Ceratodus, to which he applied the name C. Palmeri, on the grounds that the tooth 
was larger than the corresponding one in G. Porsteri, the enamel coarser, and the surface 
more undulated. 
The single tooth acquired by Mr. Krefft has since been supplemented by others 
obtained for the Queensland Museum, consisting of four pterygopalatine plates and 
five mandibulary. Of these teeth Mr. De Vis states — “ We can perceive an approximate 
similarity in their leading features, which enables us to avoid the error of considering 
them all of different species, and leads us to regard them as not only one, but one with 
the living G. Forsteri."
