specimen to Davidson convinces me that it really belongs to that group, and I 
believe that if this point had come to light at the time that he examined it he 
would probably have merged it with A. desquamata or A. reticularis.

pl. xi, figs. 11, 12. 
Remarks.—There are three fine specimens from Wolborough in the Museum of 
Practical Geology, two of which are Davidson’s figured examples. They show 
the characters of the species well, and prove that the English form, at all events, 
is certainly distinct from A. reticularis. There are two poor specimens from 
Wolborough in Mr. Vicary’s Collection, and one from Lummaton in my Collection, 
which shows a slight ventral sinus. 
Their similarity in general shape to Centronella Guerangeri, de Verneuil,' sp., 
may be noted.
