INTRODUCTORY REMARKS. 



XXIX 



I have inserted in italics have been met with likewise, at Mogadore, 

 on the opposite coast of Africa; and I may state that the little 

 which has yet been brought to light from the sandy tracts along the 

 western shores of Morocco seems to have so much in common with 

 the species which characterize the lower districts in the eastern 

 islands of these Atlantic Groups that it is impossible not to regard 

 it as a portion of the same fauna*.
