<}00 Christmas Island. 



Of the fourteen species of land-shells described, six are peculiar, 

 but allied forms are widely distributed in the neighbouring lands. 

 The same may be said of most of the other species, but two or 

 three are not known from the Indo-Malayan islands, and may have 

 reached the island from the eastward in the same way as some of 

 the mammals. 



WmQ species of butterflies are recorded, of which three are 

 peculiar, while another is a distinct variety of a Javanese species. 

 The others are Indo - Malayan, except two, which may be 

 Australian. 



Of the larger moths sixty-five species are described, ten of which 

 are peculiar. Of the remainder, most occur in the neighbouring 

 islands, but there is a considerable group of species found in 

 Ceylon, and another from the Austro-Malayan and Pacific islands. 

 Out of nine species of Microlepidoptera six are new, two of the 

 others belong to the Australian region, while the third is recorded 

 from Africa. 



Of the Hymenoptera nine out of eleven species are said to be 

 peculiar. All belong to widely distributed genera. 



The Coleoptera are represented by a much greater number of 

 species than any of the other orders of insects, eighty-four in all 

 being described, while ten others have been referred to their genera 

 only. Fifty-six species are said to be peculiar to the island, but 

 this remarkably high proportion (nearly 67 per cent.) is no doubt 

 due to the fact that the beetles of tfava are still incompletely 

 known. The remaining species are mostly either widely dis- 

 tributed forms or are Indo-Malayan. As in the case of the moths, 

 a few are identical with species from Ceylon. 



All the Homoptera are described as new. Several are related 

 to Austro-Malayan forms. Of the Hemiptera four out of six are 

 new, the remaining two are pelagic. The two new species of 

 Neuroptera belong to widely distributed genera, and the three 

 remaining species are common in the Oriental region. 



Of the Orthoptera twenty-two species are described, fourteen 

 being endemic, but nearly all belonging to widely distributed 

 genera. The remainder are either cosmopolitan, or at any rate 

 Oriental forms. 



Of three species of Chilopoda, one is PalDearctic (this was not 

 collected by me), the other two Oriental. Two out of three 

 species of Diplopoda are peculiar, the third being a cosmopolitan 

 form. Twelve species of Arachnids have been described, three 

 being new. The remainder, with the exception of one Australian 

 form, are Oriental, mostly occurring in the Indo-Malayan islands. 

 The land Crustacea are all widely distributed on the Indo-Pacific 

 coasts. 



Finally, of the four species of earth-worms two are peculiar, 

 one having allies in the Aru Islands and Ceylon, the other in 

 Sumatra. The otlier two species occur both in the Oriental and 

 Australian regions.
