young individuals, are not easily distinguishable from Stephanoceras bifurcatum, S. subfurcatum, &c. The author's general results are essentially identical with the conclusions arrived at by MM. Falloux and Waagen, but by no means in accordance with those to which Dr. Laube was led by the study of the Echinoderms, Lamellibranchiata, and Gasteropoda.
In the following list of species found at Balin, the zones to which the species belong are indicated by abbreviations as follows : —
Park. = zone of Stephanoceras Parkinsoni.
Fer. = zone of Stephanoceras ferrugineum (Fuller's Earth).
Asp. = zone of Oppelia aspidioides.
Macr. = zone of Stephanoceras macrocephalus.
Anc. = zone of Perisphinctes anceps.
Athl. = zone of Aspidoceras athleta.
Lamb. = zone of Amaltheus Lamberti.
