1 At page 398 of the ' Report on the Foraminifera ' collected during the voyage of the 

 ' Challenger,' &c., 1884, the genus Bulimina is stated to have had a geological range from the " Upper 

 Trias (Parker and Jones) " to the Tertiary and present times. This and similar statements ahout 

 other genera and species in the Report, and in memoirs and papers by other workers, including the 

 First Part of the Monograph of the Foraminifera of the Crag (page 48), is due to a mistake as to the 

 real locality of some " Blue Clay," supposed to have come from the alabaster pits at Chellaaton, 

 Derbyshire. See the paper by T. R. Jones and "W. K. Parker, " On some Fossil Foraminifera from 

 Chellaston, near Derby," ' Quart. Journ. Geol. Soc.,' vol. xvi, 1860, pages 452—458, pis. xix and sx. 



The "Triassic" age of these Foraminifera has always been doubted, and personal inquiries and 

 search were made without definite results ; but their unmistakable Liassic faeies, and the doubts 

 existing about the exactness of the workmen's statements, have led us to believe that this " blue clay " 

 came from some Lias in Leicestershire, having probably been inadvertently thrown in with the " red 

 clay " on its journey to Cubitt's works in London. 



In the ' Journal of the Northamptonshire Natural-History Society,' vol. vii, 1892, page 68, 

 Messrs. W. D. Crick and C. D. Sherborn referred to the probable Liassic character of the above- 

 mentioned blue clay. In the ' Annuaire geologique universel,' vol. ix, 1894, p. 922, the editor 

 observes, " This study permits of our fixing precisely tbe level of the ' blue clay of Chellaston,' which 

 has been attributed to the Trias, the fossils being undoubtedly those of the Upper Lias."
