différer du Carpolithes umbonatus de Sternberg; quelques points de 
cette empreinte offraient des pores peu profonds semblables & ceux 
de certains des pays chauds.’ 
Professor Unger, in his ‘Chloris protogea—Beitriige zur Flora 
der Vorwelt,’ at p.cviii. in his ‘Index of Fossil Plants,’ mentions 
the Polyporites Bowmanni, Lind. and Hutt.; and at page xxix., 
under Ord. VI., Fungi, refers to Polyporites Bowmanni, under which 
genus he places, with a query, Carpolithes umbonatus of Sternberg, 
and gives the locality of Messrs. Lindley and Hutton’s specimen, ‘In 
Schists lithant, ad Wrexham, Angliz.’ 
The mistake having been copied into such works of high repute 
as those of M. Brongniart and Professor Unger, has induced me to 
make these few remarks. The plate in Messrs. Lindley and Hutton’s 
work bears such clear evidence of the specimens being undoubted 
scales of Rhizodus, that there will be no need to figure them again, 
a reference to their plate being quite sufficient. 
It is rather singular that so evident a mistake as this is, namely, 
of describing as belonging to the vegetable kingdom a fish-scale very 
commonly found in the Coal-measures, should have passed uncon- 
tradicted for so many years. The first discoverer of the specimens 
had great doubts as to the nature of the fossils; but these doubts 
appeared gradually to have grown less, and finally disappeared alto- 
gether, as other parties who knew less of the subject treated it.

IT. OBSERVATIONS ON ‘RECHERCHES SUR LES SQUALODONS,’ par P. J. 
VAN BENEDEN. 4to., 1865, pp. 85, Pl. L-IV. Bruxelles. 
By Prof. Owrn, F.R.S. 
N the 85th volume of the ‘Memoirs of the Royal Academy of 
Belgium,’ Prof. Van Beneden, under the above title, gives an 
account of most of the specimens of Zeuglodonts which have been 
discovered in Europe, commencing with the portion of jaw with 
teeth from the Miocene of Malta, figured by Scilla, in ‘La Vana 
Speculazione disingannata del Senso,’ 1670, tab. xii., fig. 1; on 
which Agassiz founded his genus ‘ Phocodon, in the ‘ Répertoire 
d’Anatomie et de Physiologie de Valentin, 1835.—2. The next 
European Zeuglodont in point of date is the fragment of jaw and 
teeth from the ‘grés marin’ at Léognan, near Bordeaux, described, 
as part of a gigantic reptile, allied to the Iguanodon, and also to the 
Sharks, by Dr. Grateloup, under the name of Squalodon (‘Actes de 
Académie des Sciences, Belles-lettres, et Arts de Bordeaux,’ 2™¢ 
année, 1840).—38. An atlas-vertebra, from the Miocene ‘ Faluns’ at 
Salles, noticed by J. Miiller in his account of the American Zeuglo- 
donts acquired by the Royal Museum at Berlin, in the ‘Transac- 
tions of the Royal Academy’ of that city, 1847, and ‘Ueber die
