THE BIRDS OF SUMBA. 267 



Geo f f r O y u s tj in d a n ae 



after one of the indigenous names of the island of Sumba, 

 viz. Tjindana. If Salvadori had not bestowed specific rank 

 on G. floresianus and sumbavensis , I would have given 

 only a subspecific one to the Sumba-form, but in accor- 

 dance with those I call it simply G. tjindanae. Moreover 

 it would not be quite easy to place the subspecific forms 

 of these different islands in every case under the right species; 

 there would arise difficulties and, instead of creating clear- 

 ness, confusion would result. 



The differences of size, compared with Salvadori's mea- 

 surements in English inches (p. 403), are the following: 

 G. personatus: wing 5.6— 5.8 , tail 2.7—3, bill 0.8—0.9 

 G. tjindanae: „ 6.3 — 6.7, „ 3.5 , „ 1 — 1.05. 



The measurements of G. tjindanae in millimeters are: 



The future will prove , whether there are still other dif- 

 ferences between these two forms; I have now before me 

 only one specimen of personatus from Wetter to compare 

 with 3 from Sumba. 



I further wish to correct an error in my paper of 1881. 

 On page 767 it should be 



Bubulcus coromandus (Bodd.) 



instead of Herodias nigripes (T.). — Finally the following 

 remark : 



In the memoir of 1884, quoted above („Isis" p. 19), 

 I recurred to Merops ornatns Lath, from Sumba , calling 

 attention to a difference between Sumba-specimens and
