REPORT ON THE REPTILES 



COLLECTED RY THE LATE L. FeA IX WEST AFRICA 

 IJY G, A. nOULEXGER, F. R. S. 



The collection of Reptiles made l)y Fea is c[uite as important, 

 and naturally much more numerous in species, than that of Batra- 

 chians, on which I have reported above. It consists of 610 spe- 

 cimens, representing 108 species, 13 of which are described as 

 new. One of the three new Amphisbaenids is so aberrant a 

 form as to justify the establishment of a new genus. 



The study of this collection again brings out the extreme si- 

 milarity of the fauna of Fernando Po, especially at considerable 

 altitudes, with that of the Cameroon Mountains and the differen- 

 tiation of the species living on the islands of the Gulf of Guinea 

 (S. Thomé, Prince's Anno Bon) from those of the mainland 

 from which they have clearly been derived. Thus, apart from the 

 almost cosmopolitan Hemidactylus mabuia, only four species, viz. 

 Sternothaerus derbianus (fide Bocage), Mabuia maculilabris. 

 Naia nielanoleuca, and Dendraspis vii^idis, are identical with 

 continental forms, whilst the lo others must be regarded as au- 

 tochtonous.
