340 THE MARdUIS OF TWEEDDALE ON [Mar. 19, 



species by the contour of the casque. Thriponax pectoralis is 

 another species, the deviation of which from T. javensis of Luzon is 

 probably owing to isolation. In Arachnothera flammifera Mr. 

 Everett has added another Malayan genus to the_Philippine area. 



1. CaCATTJA H.EMATUROPYGIA (1). 



[Amparo, d 1 $ , July.] 



2. Tanygnathus luzonensis (3). 

 [S. Leyte, <3 > September.] 



3. LORICULUS HARTLAUBI {7)1 



[Amparo, S 2 , July-] 



I provisionally identify a series of nice examples of the South-Leyte 

 Loriculus with L. hartlaubi until further research establishes the 

 permanency of the characters whereby these Leyte birds differ from 

 those of North Mindanao and Dinagat. Five individuals are exam- 

 ples of the male bird in apparently adult plumage. They differ from 

 true L. hartlaubi in having a much smaller orange-red pectoral 

 plastron, and in its not running up to the naked chin, but stopping 

 short some way below, so that the upper throat is uniform green. 

 Above, the back is green, and not golden, nor is that of the female. 

 The dimensions are equal. 



4. ASTUR TRIVIRGATUS (11). 



[Amparo, $ , July.] 



In Mr. J. H. Gumey's opinion this Leyte example is in immature 

 plumage, and probably belongs to a male. 



5. Spilornis holospilus (16). 



[S. Leyte, c? $ , September.] 



6. Haliastur intermedius (17). 

 [S. Leyte, <S $ , September.] 



7. Thriponax pectoralis, n. sp. 



[S. Leyte, 3 $ , September.] 



Like T. javensis, but differs in having the feathers of the chin, 

 throat, sides of head and neck white, broadly centred with a median 

 black stripe, and in the fulvous-white colouring of the abdomen 

 covering the breast, each pectoral plume being centred with black. 



8. Merops PHILIPPINES (35). 

 [S. Leyte, 3 $ , September.] 



9. Merops bicolor (36). 



[S. Leyte, S 2 , September.] 



Two examples in mature plumage, two immature ; the chestnut 

 head and back in the latter mixed with green, and the middle pair of 

 rectrices not fully developed.
