817. Bhipidura rufiventris tianda subsp. nov. 



While in B. rufiventris rufiventris, pallidiceps, and assimilis the chest is pale 

 brownish grey and the white spots have a somewhat washed-out appearance, 

 not being in so sharp a contrast, in the new subspecies the chest is darker, more 

 slate-grey, and the white spots stand out bolder, in sharp contrast ; moreover, 

 the crown of the head is darker, more blackish, and the ear-coverts almost pure 

 black. The tips of the lateral rectrices are purer white. The dimensions are 

 the same. 



Type: c? ^^> Taam Island, in the Tiandu group, 25.vii.1899. Heinrich 

 Kiihn leg. No. 1,349. 



Of Bh. rufiv. tiandu I have now 12 specimens from Taam, Kilsuin, and Kur 

 in the Tiandu or Kur group, stretching from Tenimber to Ceram (Seran). I had 

 long ago noticed these differences, but the distribution seemed so very improbable, 

 as we have 21 specimens, indistinguishable, so far as I am able to make out, from 

 Add, near Great and from Little Key, as well as from Kisui and Teoor in the 

 Watubela group, north of the Tiandu Islands. But the difference of the new 

 subspecies is so striking that I cannot hesitate any longer, but herewith give it 

 a name. Perhaps the Tiandu group, for reasons unknown to us, has been peopled 

 with its birds in another way than the Watubela Islands.
