RALLIDAE 249 



palmeri of Laysan, an interesting little flightless form with a soft 

 chirping note, which the first discoverer caught with a hand-net, 

 makes its nest inider grass-tussocks. Closely allied to Porzana 

 is Crecisei's, a genus of a dozen species ranging from the United 

 States to tlie Galapagos, Chili, and Paraguay ; two at least of 

 them heing remarkable for building a spherical nest with a side 

 entrance in coarse herbage or low l:)ushes, while one is said to 

 make a sort of ladder to reach a platform before its porch.^ Liiii- 

 nocorux niger of the Ethiopian Eegion is a glossy black bird 

 with red feet and greenish bill, which walks upon the leaves of 

 water-lilies and such plants, like a Jacjana. 



Amanroriiis, inhabiting the Oriental Eegion and extending to 

 New Britain, links the foregoing genera to the Gallinnles. A. 

 phoenicura is a dark greyish bird with white under parts and 

 chestnut flanks, tlie other three species being duller. 



Trihonyx mortieri, the " Native Hen " of Victoria, South 

 Australia, and Tasmania, and T. ventralis of consideral)ly wider 

 range, are respectively ruddy- and olive-l:)rown forms, with blackish 

 tail and vent, slaty lower surface, and white flank-marks. They 

 appear at times in flocks, which arrive and depart with equal 

 suddenness, destroy the settlers' crops, strut about like fowls, and 

 in many respects resemlile Moor-Hens in habits, nests, and eggs. 

 The legs are unusually powerful. 



Gallinula extends over the greater part of both hemispheres, 

 and is represented in Europe, Asia, and Africa by our common 

 Moor-Hen {G. chloropus), dark olive-brown above and grey below, 

 with white lower tail-coverts, white flank-stripes, red frontal plate, 

 and scarlet garter on the tibia. G. gahatn of most of the New 

 World diflers in the posteriorly truncated shield, but G.sandvicensis 

 of the Sandwich Islands is barely separable. The smaller African 

 G. angulata, G. fenehrosa of Australia and New Guinea, and G. 

 frontata of the two last-named countries, the Moluccas and Borneo, 

 complete the group ; unless G. pyrrhorlioa of Madagascar and G. 

 flionTjsiana of St. Denys be accounted distinct from G. chloropus. 

 The flightless G. {Porphyriornis) nesiotis of Tristan da Cunha 

 and G. comeri of Gough Island have already been mentioned. 

 Gallicrex cinerea, the " Water-Cock " of the Indian Eegion, which 

 reaches Japan, is dull black, with lighter edges to the feathers 

 above, a yellow and red bill, and red frontal shield. A pinkish
