Ptilotis forresti, sp. n. 



Similar to Ptilotis sonora, but paler on the back and 

 under-surface, especially so on the rump, which is of a 

 light brown colour. The uropyg'ial region is noticeably 

 lighter than the rest of the back, which is not the case in 

 the typical P. sonora. Owing to the faintness of the stria- 

 tions on the breast and flanks, the underparts are not so 

 dusky : the abdomen and under tail-coverts are unmarked, 

 being of a dirty white colour, washed with isabelline. 

 Total length about 7 inches, culmen 0*8, wing 3'6, tail 3*7, 

 tarsus 1. 



In the large series of P. sonora at the British Museum 

 there is a single skin from the late Mr. Gould's collection 

 agreeing fairly well with the two birds from Alexandria. 

 The label unfortunately gives no locality other than 

 " Australia '" ; it bears the MS. note " light variety," 

 showing that Mr. Gould did not consider the specimen as 

 typical. 



MiRAFRA RUFESCENS, Sp. n. 



Resembles M, woodwardi in the fulvescent tone of its 

 plumage, but is everywhere paler. The brown centres to 

 the feathers of the back are less conspicuous than in the- 

 typical examples of M. woodwardi, while the striations on 

 the chest are almost obsolete. As this pale form is 

 distinctly rufous in the coloration of its plumage, it is 

 obviously separable from Mr. Hall's desert race, a greyish 

 form that he has raised to sub-specific rank under the 

 name of M. horsfieldi pallidus (Emu., Vol. III., p. 232). 



Mr. W. R. Ogilvie-Grant sent descriptions of the 

 following new forms of birds which had been collected 

 on the higher slopes of the eastern part of the Ruwenzori 

 Range, Central Africa, by the Ruwenzori Expedition : — 



Apalis AFFiNis, subsp. n. 



Ad. $ and ? . Most nearly allied to A. porphyrolcema, 

 Reichenow and Neumann, but with the throat-patch of a
