EXPLANATION OF PLATES. 



The figures on the followiiio- phites were prepared by tracing- from 

 photographs as is shown in some eases by a lack of ))lhitei'al synmietry 

 due to the angle at which the photograph was taken. In this way 

 accuiacy of outline and in the relation and proportion of the parts was 

 assured, while at the same time other and non-essential features could 

 be omitted, gfiving- the figures the character of diagrams. 



The plates are ))y the author.
