 take the name Gracula javana, because Eulahes javanus Cuvier ' is the 

 next available specific designation. This change Doctor Hartcrt has 

 already explained. 2 



LAMPROCORAX PANAYENSIS HETEROCHLORUS, new subspecies. 



Subspecific characters. — Similar to Lamprocorax panayensis striga- 

 tus, from Java, but Yery much larger, and plumage of male through- 

 out more bronzy or oily green. 



Description.— -Type, adult male, No. 170996, U.S.N.M.; Pulo 

 Mobur, Anamba Islands, August 26, 1899; Dr. W. L. Abbott. 

 Entire plumage, excepting the remiges and rectrices, metallic bottle 

 green, with a slight bronzy tinge, the chin and throat with a some- 

 what purplish sheen; remiges and rectrices blackish on upper sur- 

 face, with steel greenish, bluish, and purplish reflections; lower 

 surface of tail and wings blackish clove brown, the under wing- 

 coverts and axillars margined with metallic green. 



This new race is very distinct and separable at a glance from 

 Lamprocorax panayensis strigatus of Java by the characters above 

 given. It is, however, more closely allied to Lamprocorax panayensis 

 panayensis, from which, in the male, as comparison with a large 

 series of Philippine specimens shows, it differs in its more grassy, 

 less oil} 7 or bronzy green upper parts, and particularly in its decidedly 

 less bronzy lower surface, which is also much brighter green, par- 

 ticularly on the posterior portions, where Lamprocorax panayensis 

 panayensis is nearly always distinctly grayish. 

 Four specimens are in the collection, as follows: 

 Adult male (type), No. 170996, U.S.N.M.: Pulo Mobur, August 26, 

 1899. Length, 229 mm. 



Adult male, No. 170997, U.S.N.M.; islet near Pulo Mobur, August 

 26, 1899. Length, 216 mm. 



Immature male, No. 170933, U.S.N.M.; Pulo Siantan, August, 

 1899. 



Immature male, No. 170998, U.S.N.M.; islet near Pulo Mobur, 

 August 26, 1899. Length, 203 mm. 



The type (No. 170996) is in perfect plumage; and the other adult 

 male (No. 170997) is nearly so, though molting the under wing- 

 coverts, with some of the wing-quills and body feathers. One of 

 the immature birds (No. 170998) is in the juvenal plumage, which 

 closely resembles that of the adult female, but is molting many of 

 the body feathers. The other immature is similar but is more 

 extensively glossy green above, has the breast nearly solid green, 

 and the posterior lower parts much more mixed with glossy green; 

 it is molting wing, tail, and body feathers.
