Abstract

The new genus Idosocrinus is proposed for a remarkable type of crinoid occurring in the Thornton Burn section of the Calciferous Sandstone Series (Lower Carboniferous) of East Lothian, and two species are recognized. In general habitus the new genus resembles Phanocrinus Kirk, but differs in the character of the left and right posterior primibrachs, which extend outward from the cup in the form of strongly developed spines. Two new specimens of Anemetocrinus wilsoni Wright are also figured.
