Foraminifera. — Very little has hitherto been known of this 
beautiful class of Microzoa from the Carboniferous Limestone, and 
those I was fortunate enough to obtain from the north of England 
lead veins will throw considerable light upon them. This will 
especially apply to the genus Involutina, which until lately was 
only represented by a single living species, the I. liassica, Jones ; 
but two had since been figured by Terquem, the I. ^olymorj)ha and 
the I. silicea, from secondary beds. My series not only carries 
back the above secondary species to palaeozoic times, but associated 
with them are eight others ; so that under these peculiar conditions 
eleven species of this hitherto Httle known genus occur. Dentalina 
pauperata, D'Orb., a now living species, which has been traced 
back through tertiary, liassic, and Permian formations, not only 
in this series goes back to the Carboniferous Limestone, but I 
have been fortunate enough to discover a single specimen in the 
Wenlock shale, an evidence of a delicate microscopic shell having 
existed through a long series of ages to the present time. The 
Tinoporus levis, P. and J., another recent species, would pro- 
bably be included in the list, though it requires more examination ; 
added to which would be the recent species Textularia sagitata, 
De France, and also the genus Fusulina. Associated with the 
above were some nearly spherical bodies more or less drawn out at 
the two poles, as though they had formed portions of a monihform 
test. These were suggested by Mr. H. B. Brady, who had examined 
the series, to be the joints of a large Lituola, which he provisionally 
named L. gigantea, though the specimens were too limited for a
