Messrs. Waagen and Jahn devote two pages and seven figures of the ponderous tome 

 above cited to a fragment from the White limestone, stage F 2 , of Koneprus, Bohemia. It 

 was originally labeled by Barrande Lecanocrinus bohemicus, but Waagen and Jahn incline to 

 refer it with doubt to Ichthyocrinus, in which they are clearly justified. Enough remains of 

 the specimen to indicate its generic affinities, and that it belongs to a species with a low ovoid 

 crown, probably small basals, and perhaps ornamented surface ; it belongs to the type of 

 species like /. gotlandicus or /. corbis, and is of interest chiefly to show the occurrence of the 

 genus in Bohemia. 



Type. In the Collection Barrande, Prague, Bohemia. 



H orison and locality. Lower Devonian, stage F 2 (perhaps = Helderbergian) Koneprus, 

 Bohemia.
