are large numloers of duplicates stored in boxes, the great 
zoological groups of the period are represented, but the Crinoids, 
Trilobites, Brachiopods, and Fishes are particularly fine. 
The localities are mostly Yorkshire and Derbyshire, but 
other countries, especially Northumberland, Ireland, Scotland, 
and N. America are also well represented. There is a 
set of corals, mostly polished, from the Bristol limestone, 
and of crinoids some 300 very choice specimens, belonging 
to numerous species. These include six species of Woodocrinus 
— W. expansus, W. dichodacfyhis, W. macrodactijlus, W. 
goniodactylus, W, Jongidacfylus^ and W. fimhriatus, with the 
type specimens of each; also the beautiful figured type of 
Hydreionocrinus Woodianus. The or sea urchins, are 
represented by the Archceocidaris TJrii^ Melonites Etheridgii, and 
Falcechinus syohericus, the latter being the figured specimen. 
The Carboniferous Trilobites, of which there are 95 speci¬ 
mens, belonging to the genera, Phillipsia, Griffithides^ and 
Brachymetopus, also form a valuable part of the carboniferous 
series. The Brachiopods are extremely choice, numbering over 
1,200 selected specimens, and including 7 figmed types drawn 
and described by Mr. Davidson in the monographs of the 
Palteontographical Society. 
The remaining groups of the Mollusca are also well repre¬ 
sented, there being many choice specimens. 
In the Coal Measure group the land Flora is very fully and 
beautifully illustrated by some 220 specimens of Ferns, Tree 
Ferns, Equiscta, and Lycopods^ found in the coal shales and 
sandstones of Yorkshire, Durham, Newcastle, Edinburgh, 
Somerset, and elsewhere. From Ireland we have large fronds 
of the noble fern Adiantites Ilihernicus out of the Kiltorcan 
sandstone. 
Of the Fishes of the coal period there are 90 specimens, 
including some very fine GyracantJms and BleuracantJnis^ and 
the figured type of AmpJiicentruni granulosum; also good 
examples of Ilegalichthys. 
5. The Permian rocks are far from being so prolific of 
organic remains as the carboniferous, but Mr. Wood’s collection 
of their fossil contents is unusually rich and complete. They
