xvi PREFACE 



Sketches, but has most kindly furnished an 

 additional cut (p. 89) from an original sketch of 

 his own. 



In the production of all these, an effort has been 

 made to supply figures which are not only 

 appropriate to the text, but have the merit of 

 being accurate delineations of the species they 

 are intended to represent.
