108 Anniversary Address to the 
which, as yet, has given us no separate memoir on British 
fossil plants. 
The Amorphozoa come next. In 1843, 76 named forms 
were recorded. In 1853, the number is increased to 116. 
The increase is in a great measure due to the labours of Mr 
Toulmin Smith among the Ventriculide, which, notwith- 
standing the arguments of their investigator in advocacy of 
their Polyzoan, and consequently Molluscan origin, natural- 
ists are generally of accord to keep in their old place beside 
the Sponges. 
The Foraminifera, 82 of which are mentioned as named 
types in the list of 1843, have increased to 168, besides 
numerous indications of unpublished and, as yet, unnamed 
forms. The next ten years will probably triple the amount 
of named fossil species of these exquisite minims of creation. 
The additions are chiefly new identifications of British fossils, 
with species described by continental authors, especially by 
Alcide d’Orbigny and Reuss. The merit of determining 
these is, I believe, in great part due to our Assistant-secre- 
tary, Mr Rupert Jones, whose authority stands very high in 
all departments of microscopic paleozoology. Mr Jones 
himself is an addition to the list of British Palceontologists 
during the last ten years, and one we all welcome. The 
labours of Dr Williamson and Dr Carpenter have also done 
much towards clearing up our fossil Foraminifera; and the 
untiring exertions of Mr Harris, of Charing, though incon- 
Spicuous in print, have, I believe, been a chief source of fresh 
materials towards the history of our cretaceous species. 
In the first edition, the Zoophyta are combined with the 
Bryozoa. When the latter are eliminated there remain 183 
zoophytes, chiefly corals. This number has been prodi- 
giously added to within the last ten years, no fewer than 438 
species being enumerated in the new catalogue. The in- 
crease in this instance is due to an entirely new treatment 
of the subject. To Milne-Edwards and Jules Haime a large 
proportion of the additions are indebted for their place. Mr 
Lonsdale and Professor M‘Coy have also contributed exten- 
sively. |
