The Rev. H. A. Macpherson exhibited a nestling Duck, 

 whicli was the offspring of a female Anas hoscas and a male 

 Dafila acuta. 



The Hon. Walter Rothschild sent for exhibition the 

 type of a new Thrush, which he described as follows : — 



Geocichla dumasi, sp. n. 



This fine new species has been discovered on the Island of 

 Buru by Mr. Dumas, a companion of the late Mr. A. H. 

 Everett, and is perhaps nearest to G. dohertyi, from the 

 Lesser Sunda Islands, but is quite distinct. 



c^ ad. Whole upper surface bright olive-rufous brown, 

 ivith two tufts of creamy white feathers, one on each side of 

 che rump. Lesser upper wing-coverts like the back ; greater 

 upper wing-coverts black, with two rows of large round 

 white spots. Remiges blackish brown ; the outer webs of the 

 primaries with narrow, those of the secondaries with broad, 

 olive-rufous borders. All wing-feathers, except the outer

Mr. Ernst Hartert exhibited specimens of six new 

 species of birds from Buru. They had been collected by 

 Mr. Dumas, who had accompanied the late Mr. A. H. Everett 

 during his last expeditions. Mr. Hartert pointed out 

 that some of the forms were of great zoo-geographical 

 interest. The entire collection would be fully discussed in 

 ' Novitates Zoologicse.^ 



The new forms were described as follows : —
