EXPLANATION OF THE PLATES. 



A reference is given after each figure to a certain page of the text. In the case of 

 figures which illustrate entire specimens, the reference given is usually to the page in the 

 systematic part of the Eeport on which the species is first described. But with those 

 figures which represent structural details, reference is given to the page containing the 

 explanation which the figure was designed to illustrate. This is sometimes in the 

 morphological and sometimes in the systematic part of the Eeport. In a few cases there 

 is no special reference to a figure in the text ; and the number of the page following its 

 explanation is either that of the specific diagnosis, or that of a page containing a 

 description of structural peculiarities which is more or less illustrated by the figure in 

 question.
