432 MR. G. R. GRAY ON NEW BIRDS [DcC. 10, 



Ptilonopus roseipectus, G. R. Gr. 



Approaches the P. viridis, but is smaller and without the gre3'ish 

 white on the shoulder ; this colour is less extended ou the face, where 

 it is rather inclined to be of a bluish white. It has only a patch of 

 deep rose-colour on the breast, which appears to be wanting in the 

 female. The tips of the tail-feathers are without the bright-yellow 

 margins. 



Total length 7" 6'", bill from gape 8'", wings 4" 5'". 



Hab. Waigiou, Gagie, and Mysol. 



Henicophaps albifrons, G. R. Gr. (PI. XLIV.) 



Front white ; fuscous-rufous black, tinged with glossy green, on the 

 back and tertials ; greater wing-coverts with golden-coppery gloss ; 

 abdomen grey fuscous ; under tail-coverts rufous. 



Total length 13" 6'", bill from gape 1" 2i"', wings 7'". 



The bill is like that of Chalcophaps, but the apical portion occupies 

 rather more than half its length ; the basal part of culmen is flat- 

 tened and rather broad. 



Hab. Waigiou. 



Megapodius freycineti. 



Mr. "Wallace* refers to what he considers to he two species of this 

 genus, and states that their " bill and feet are different in size ; " but 

 the variations referred to seem to me to be only caused by the dif- 

 ference of age. 



Rallus plumbeiventris, G. R. Gr. 



Head, neck, and breast rufous ; back and wings olivaceous brown; 

 tail-coverts and tail black ; abdomen plumbeous. 



Total length 11" 3"', bill from gape 1" 9"', wings 7" 3"'. 

 Hab. jNIysol. 



Mr. Wallace has thus increased the Avifauna of New Guinea and 

 its neighbouring islands to upwards of three hundred species. 

 Amongst these his diligence has added some sixty-five new species to 

 our knowledge, many of which are not without interest to ornitho- 

 logical science. 



A table of specific names is added to this paper, as it will best ex- 

 emplify the distribution of the several species among the islands that 

 constitute the localities of the New-Guinean Avifauna ; it will also di- 

 stinguish those birds that at pr^rnt appear to be peculiar to one island. 



t in front of a specific name indicates those species, of the W^aigiou 

 and Mysol collections, of which this paper more especially treats. 



** before the name show the new species added to the New-Gui- 

 nean avifauna by Mr. Wallace. 



* in column records those species of author's which have been 

 given as inhabitants of the peculiar locality to which the column is 

 dedicated. 



** in column point out the localities of those species of which 

 Mr. Wallace had obtained specimens.
