else compiled from the numerous books and magazines 

 referring to the subject by German and French as well 

 as English authors. References will be given in each 

 case where a fuller description may be found in English 

 periodicals. 



The study of local fauna, even of such a puny 

 character as that with which the present work deals, 

 cannot be without interest even to the most casual

 the attempt may be, must always be welcomed and 

 encouraged by every scientific enthusiast. 



In conclusion I beg to offer my best thanks to
