as bimaculata. Not only occur both forms, i.e. the one with the orange-rnsty 

 breast and the one with the wliite breast, on Morty Island, but also on Batjan and 

 Halmahera, and we iind every iiitergradation between the two. Moreover, exactly 

 the same variation occurs in the allied }tonarchn bern.-itcini on Obi.

 various rai«s of .1/. clinb/bcoceplialuti. The form niteiis was first described from 

 Batjan, wliere it is common : Wallace, Bernstein, Guillemard, Platen, Doherty. 

 Mr. Dumas obtained it also on Morty.

Though it has become customary to regard all the black and white " SkkIo- 

 provtiie" from the Moluccas to Australia as belonging to one form, this is obviously 

 wrong, if a large series is laid out and looked at. It strikes at once even the casual 

 observer that those from Australia have smaller bills, and such is indeed the case. 

 While I am not able to make any divisions between those from the Solomons, New 

 Britain, New Ireland, and New Guinea to the Moluccas, I must separate the 

 Australian form, which has to bear the name

{Rkipidiira motacilloides Vig. & Horsf., Trans. Linn. Soc. \v. p. 248. 182() : type 

 St. George R., Australia), as it differs constantly and strikingly by its smaller bill. 

 In general its dimensions are slightly less all round, but nothing is so evident and 

 constant as the smaller bill.

5:3. Muscicapula maculata westermanni iSharpe. 

 Two adult i/iale.'< were obtained on Batjan, between ;3U()0 and 700U ft. high, in 

 June and .July 1'.MI2, by Mr. Waterstradt. This species was hitherto only known to 

 "extend eastwards as far as Celebes. Its occurrence in the Moluccan Islands extends 

 its area considerably. It is doubtless only found on the high mountains.

Mr. John Waterstradt sent a large series of a Muscicapula, obtained on the 

 monutains of Batjan, between oOUU and 7000 ft. high. These birds at a glance 

 closely resemble the well-known M. hypcrythra, of which I have a large series for 

 comjiarisou, but dill'er as follows : The male has the throat and breast paler orange- 

 rulons, the abdomen distinctly more whitish, the tlauks darker, more olivaceous.
