14. Loriculus Siquijorensis. sp. nov. Siquijor. Adult male 

 with large quadrangular spot of crimson upon the forehead and 

 crown, ending sharply in the general green color of the upper sur- 

 face. Adult female and young male: Red spot upon the forehead 

 veiled by blue tips to the red feathers. 



15. Loriculus Mindorensis. sp. nov. Mindoro. Adult with 

 a broad crimson band across the forehead below the eyes, ending 

 sharply in the green of the upper surface. 



16. Loriculus Worcesteri. sp. nov. Samar, Leyte. The 

 crimson of the upper surface covering the forehead, crown and 

 nape, where it tapers to a point. It is distinguished from L. Hart- 

 laubii, its nearest ally, by the much fainter wash of orange red 

 upon the mantle and interscapulars, and by the shape of the red 

 markings of the head and nape. In L. Hartlaubii the crimson area 

 grows wider on the nape, where it ends broadly. 



All adult male Philippine Loriculi observed, have an orange- 

 red spot upon the breast, and green cheeks. All adult females and 

 all young males in their second plumage have blue on the cheeks 

 and throat, and lack the orange-red plastron. All young birds in 

 first plumage have the entire head green, and the rump scarlet.
