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, Lamellibran- 
chiata, and Gasteropoda. 
In the following list of species found at Balin, the zones to which 
the species belong are indicated by abbreviations as follows :—
