FOUR NEW BIRDS FROM THE PHILIPPINES AND 

 GREATER SUNDA ISLANDS. 1 



BY J. H. RILEY. 



The following four apparently unnamed forms have been 

 discovered in a further study of the collection made in Celebes 

 by Mr. H. C. Raven 2 and are herewith described. 

 Anthreptes malacensis paraguae, subsp.. nov. 



Type, adult male, U. S. National Museum, No. 233332, Puerto Prin- 

 cesa, Palawan, Philippines, December 14, 1891. Collected by D. C. 

 Worcester and F. S. Bourns (original No. 3274). 



Similar to Anthreptes cagayanensis Mearns, but the metallic violet 

 reflections more uniform and deeper on the crown and upper back and 

 the breast a clearer yellow. Wing, 67; tail, 45; oilmen, 17 mm. 



Remarks. — This race is founded upon a good series of both sexes. All 

 the males agree in having the crown, hind-neck, and upper back deep 

 metallic violet and only show dark green reflections to any extent when 

 held with the bill towards the light. Anthreptes malacensis wiglesworthi 

 has the crown and upper back a deep, bright, shining coppery green; in 

 Anthreptes malacensis cagayanensis these parts have a metallic violet 

 wash in addition to the green; while in Anthreptes malacensis paragua 

 the metallic violet wash is intensified and the metallic green has almost 

 entirely disappeared. 



Females of Anthreptes malacensis paraguce are similar to the same sex 

 of Anthreptes malacensis cagayanensis but the yellow below is slightly purer, 

 not quite so greenish. 



Anthreptes malacensis bornensis, subsp. nov. 



Type, adult male, U. S. National Museum, No. 211591, Po Bui Island, 

 Sandakan, British North Borneo, March 1, 1908. Collected by Paul 

 Bartsch.
