Gko<;kapiiical Disti{if>ution. 



The Jacanas are pretty well distiibutetl throughout the globe, 

 and are represented in all its various zoogeographical divisions. 

 Commencing in the far East we find in the Australian Region 

 that the continent of Australia possesses but one species, the AI. 

 gallinacens^ procured in South Australia, at Port Essingtoii, 

 inQiieensland, and the north-eastern portion of New South Wales. 

 This species extends its range into New Guinea and Mysol of 

 the Papuan group of the Austro-Malayan Subregion, and is also 

 found in the Austro-Malayan islands Celebes ami Banda, though 

 perhaps the latter may be doubtful. The Oriental Region contains 

 two species, H. chirurgus and M. indicus^ the range of which 

 is very similar, extending through India, as understood, from 

 Caslunere, through Cochin-China and Siam of the Indo-Ciiinese 

 Subregion, into the Indo-Malay islands of Sumatra, Java and 

 Borneo, and H. chirurgus is also found in the Philippines. Cey- 

 lon also contains both species, and Formosa of the Oriental Region 

 possesses H. chirurgus. The Ethiopian Region contains three 

 species, M. africaiins^ M. albinucha, and A. capensis. The 

 first extends from Natal on the southeast coast, through the lake 

 regions to Zanzibar on the north, and across the southern portion 

 of the continent through Damara-Land to Senegal on the south- 

 west coast, xi. capeiisis is found from Algoa Bay, across the 

 southern portion of Africa, into Damara-Land. Madagascar 

 (Malayan Subregion) contains M. aj'ricamis and j\I. albiinicha.
