be distinct from the type. The distribution of the genera of the Paradiseidae does not give any clue to 

 explain the apparently arbitrary habitats of many of the species. The larger number of them are met with in 

 New Guinea, some restricted to it, while others are represented in the neighbouring islands and continent of Australia. 

 Besides New Guinea, only one island, or rather group, possesses a genus peculiar to itself — Gilolo and Batchian, 

 where Semioptera is found ; while Sericulus and Ptilonorhynchus are confined to Australia, the last being a form closely 

 allied to Chlamydodera, which, however, has its representative in the interior of New Guinea, apparently a straggler, 

 as our limited knowledge causes us to view it, because, with this single exception, all the species of this last-named 

 genus are found in Australia, which would therefore appear to be the division of the earth in which it was originally 

 produced. 



The following review exhibits more minutely the geographical distribution of the species. 



PARADISEA.
