EXPLANATION OF THE PLATES. 



Note. — Slight differences may be noted in places between the test and some of the 

 figures on the earlier plates. The specimens from which these drawings were made are no 

 longer accessible, and the descriptions are taken from others, which results in bringing 

 individual variations into prominence.
