Show 692 THE MARQUIS OF TWEEDDALE ON [NOV. 6, same species. If this is correct, C. affinis is an exception to the rule of equality in size which prevails among all the other known Asiatic species of this genus. Moreover Bernstein has shown that the two Javan birds differ in their anatomical structure (conf. Walden, Trans. Zool. Soc. viii. pp. 56, 60). 24. BUCEROS HYDROCORAX (66). [Monte Alban. o*: iris red ; bill red ; nails dull black ; orbital skin yellow ; feet brownish red.] The whole of the back and shoulders of the two examples obtained by Mr. Everett are smeared with an olive-yellow powder, seemingly taken from the oil-glands at the root of the tail. Mr. Elliot (Monogr. Bucerotidae, pt. ii.) countenances the erroneous statement of the older authors that this Hornbill also inhabits the Moluccas. 25. PENELOPIDES MANILLJJ (69). [Monte xAlban. d • iris crimson ; orbital skin and base of mandible white ; bill dark brown; the casque transparent horn-brown ; the oblique bars on the maxilla ochre-yellow ; feet and nails dull black; fruit in the gizzard.] Mr. Sharpe (t. c. p. 309) identifies a Cataguan example of this genus in the British Museum with P. panini. If the identification and locality are correct, both species inhabit the island of Luzon. 26. LANIUS NASUTUS (70). [San Mateo, a, d '• iris orange-brown ; bill, legs, and nails black. b, d' iris pale orange-brown ; bill, legs, claws black, c, 2 '• his warm brown ; bill and legs black.] The four examples sent by Mr. Everett are in mature plumage. They are difficult to separate from the grey-backed form of India, L. nigriceps. The only apparent difference is, that in the Luzon bird the rufous of the uropygium and upper-tail coverts is not so bright, and that the grey on the back extends lower down. Dimensions about equal. 27. LANIUS LUCIONENSIS (72). [San Mateo, a, d * iris dark-brown ; bill purplish leaden ; legs dark bluish grey ; claws black, b, d * iris dark brown ; bill purplish leaden ; legs bluish ; claws dark brown, c, 2 '• iris dark brown ; legs dark lead ; claws black ; bill purplish brown.] The two examples marked § have the cheek-stripe brown, not black ; and the pectoral feathers and upper tail-coverts are edged with brown. 28. ARTAMUS LEUCORHYNUS (73). [San Mateo, a, d' iris dark brown; bill whitish blue, tipped black ; legs darkest lead-grey. b, d' his chocolate; bill pale bluish; feet and claws black, c, d: iris dark brown; bill pale-bluish- grey, tipped black ; legs darkest lead-grey ; claws black, d, 2 * iris dark brown; bill pale whitish blue, tip black; legs dark leaden.] |
