INTRODUCTORY REMARKS, XUl 



But space will not permit me to enter into further details. Suf- 

 fice it to add that the two eastern islands of the archipelago, Lanza- 

 rote and Fuerte Ventura, seem to possess more of an African element 

 than the central and western ones — as is evinced by their very 

 peculiar fauna, which has a good deal in common with that of the 

 opj)osite coast of Morocco ; and they appear to me to bear about the 

 same relation to the remainder as, in the neighbouring Group, Porto 

 Santo does to Madeira proper. The entire Canarian Catalogue, how- 

 ever, is not more indicative of a southern latitude than is the case with 

 that of Madeii'a (at any rate not more so than would be naturally 

 anticipated were the slight additional distance to the south measured 

 over a continuous tract) — its general character being much what we 

 should a jpriorl expect to find on the southern Mediterranean limits ; 

 though at the same time there is, as in Madeira, so large an assort- 

 ment of purely endemic forms as perhaps to be suggestive rather 

 of a sejiarate " Atlantic province." 



Although only a portion of them have been described in this 

 volume, I believe that about 30 genera and 540 species have been 

 established by myself (partly in detached Papers, severally referred 

 to) amongst the Canarian Coleoptera here enumerated. Whatever 

 other forms there are (in addition to these) which it has fallen to 

 my lot to be the first to enunciate are found at Madeira likewise, and 

 were therefore published amongst the novelties of that Group.
