N. B. — The preparation of plates for this Bulletin was in some respedls 

 an after-thought; in fact they were not completed until most of the press 

 work was done ; hence no reference to them will be found in the text. 

 Their number is however so small that little or no inconvenience will be 

 experienced from this omission. — Ed.
