IX.—Note on the Deciduous Septa of Ascoceras Murchisoni, Barrande

Published online by Cambridge University Press:  01 May 2009

Extract

An interesting paper has lately been contributed to this Magazine (December, 1888, p. 532), by Dr. Gustav Lindström, of Stockholm, in which he announced his discovery of the earlier, or Nautilus stage, as he termed it, in several specimens of Ascoceras from the Silurian of the Island of Gothland. I find, however, in looking over the supplementary volume of the Syst. Sil. du centre de la Bohême,3 that Dr. Lindström's discovery has been anticipated by M. Barrande, who observed and described two of the normal chambers (Nautilus stage, of Lindström) attached to a specimen of Ascoceras Murchisoni from the Silurian strata (Étage E) of Karlstein in Bohemia.
