an indication of white at its head. In the arrangement of 

 the feathers on the lower fore-neck it agrees fully with 

 the preceding specimen. The same does our third adult 

 specimen, the above-named of the missonary-union. The 

 latter one, however, is smaller than the two others, meas- 

 uring: total length about 1250mm.,tarso-metatarsus 250 mm. 

 The type measures: t.l. about 1350 mm., tarso-met. 300 

 and the Hattam-specimen t.l. about 1330, tarso-met. 300.

An adult specimen. — This bird agrees perfectly with 

 examples from the Moluccas. We have of this form an old 

 female and two pulli from Halmahera collected by Bern- 

 stein, 4 specimens from Ternate by Bernstein, 5 from 

 Ternate by von Rosenberg, 2 from Ternate by van Mus- 

 schenbroek, 1 from Tidore by von Rosenberg, 4 specimens 

 from Misool by Hoedt, 2 from Amboina by Hoedt and 1 

 from Ceram presented by van Musschenbroek. The Ceram 

 bird, collected 19 October 1873, has the breast light ashy 

 grey, as has also a specimen from Ternate, dated 2 February 

 1875; another one from Ternate, collected 4 June 1874 

 and presented in 1878 by van Musschenbroek, has the breast 

 light slaty grey, while the abdomen is nearly quite white. 

 The three latter ones are young birds. The adult birds 

 have the breast and the abdomen slate grey, the abdomen 

 with a slight brown tinge passing into the rufous colour 

 of the vent and undertailcoverts. The bills of young birds 

 are of a light colour, missing however the strong yellow 

 greenish tinge of those of the adult ones. Salvadori's 

 supposition, that Schlegel's Gallinula Frankii should be 

 the young of this species is not right. The former is in- 

 deed another good species of the genus Amaurornis, quite
