Mr, Whitehead sends one example of theGuimaras Streaked 

 Bulbulj which Prof. Steere separated under the above name. 



I must say I find the Bulbuls allied to typical /. philip- 

 pensis extremely puzzling, and it is very difficult to know in 

 what way it is best to treat them. Prof. Steere regards the 

 birds from Luzon, Marinduque, Samar, Leyte, Eohol, and 

 Cebu as I. philippensis , while he separates those inhabiting 

 the islands of Panay, Guiraaras, and Negros under the name 

 of /. guimarasensis. Messrs. Bourns and Worcestei* \cf. Occ. 

 Pap. Minnesota Acad. Sci. i. no. i. p. 60 (1894)] are of 

 opinion tliat Prof. Steere is in error, and reunite the birds 

 from all these islands under the name of /. philippensis . On 

 the whole, however, I am in favour of following Prof. Steere, 

 for I find certain constant differences which appear sufficiently 

 important to justify the separation of /. ffuiniarasensis at least 

 as a subspecies. The much larger bill of this bird and the paler 

 colour of the throat are differences easily appreciated, and, 

 moreover, we are told that the notes of the two forms in 

 question are very different.

La the British Museum tl ere are typical specimens of 

 /. phil'qypensis obtained on the island of Panaon, to the south 

 of Leyte, and at Butuan, in the north of Mindanao. In the 

 south of this island and in Basilan /. phi/ippensis is repre- 

 sented by the much larger /. rufigularis, Sharpe, which is 

 without the pale shaft-stripes on the throat. 



Prof. Steere gives Luzon and Mindanao as the habitat 

 of /. rufigularis \ the former locality is apparently given in 



* Five Cebu birds liave the bill alightly larger (0-98 iucb) tbautj'pical 

 /. philippensis from Luzon and the other islands, and in this respect 

 somewhat approach I. guimarasensis ; but they have the throat more 

 brightly coloured, and, as will be seen, the difference in the length of 

 the bill is but slight.
