Abstract
The present note relates to two specimens. One was obtained by Mr. G. E. Dibley, F.G.S., from the Micrazter cor-anguinum zone of the Chalk at Gravesend, and now forms part of the British Museum collection (register number C. 10576); the other is in the collection of Dr. H. P. Blackmore, F.G.S., of Salisbury (to whom I am indebted for the loan of the fossil), and was obtained from West Harnham, near Salisbury, at the base of the zone of Actinocamax quadratus. Being the more nearly perfect, the Salisbuiy specimen is described first.
