are known to me. The distribution of Christmas Island Moths 

 seems to show very clearly that it has no connection with the- 

 Malayan sub-region, bnt is very intimately related to the Ceylonese 

 sub-region, with a less strong relationship to the Australasian fauna' 

 found in Queensland, J^ew Gianea, and the Pacific groups. In the 

 collection hardly any of the numerous species confined to the Malayan 

 sub-region occur ; and where there are closely allied species in the- 

 Ceylonese and Malayan faunas, it is the species of the former region 

 that occur in Christmas Island, not of the latter, and this holds with 

 regard to large conspicuous species whose distribution is well known, 

 and not only small and obscure species which might be supposed tO' 

 have been overlooked in the Malayan sub-region.
