Leucodiopterum sinense (Gmel.) ; Swinhoe, Ibis, 1870, p. 250. Trochalopteron canorum (Linn.); Sharpe, Cat. B. Brit. Mus. vii. p. 376 (1883); Styan, Ibis, 1893, p. 427; Hartl. Abh. nat. Ver. Bremen, xiv. p. 348 (1898). " Iris greenish yellow; bill yellow-red-brown; feet pinkish brown."-J". W. Interior of Hainan (Swinhoe). Interior of South-west Hainan (Styan Sr Hartlaub). 74. *GARRULAX SEMITORQUATA, sp. n. Adult male. Most nearly allied to G. pectoralis (Gould), having the ear-coverts similarly striped. It is, however, much smaller and at once distinguished by the following characters:-the black band surrounding the throat is widely interrupted in the middle, the outer webs of the outer primary-quills are brownish buff instead of white, and the tips of the tail-feathers are fulvous buff. Adult female. Differs from the male only in having the white streaks on the ear-coverts more strongly marked. " Iris straw-colour to reddish brown ; upper mandible lead-black, lower and feet lead-grey."-J. W. Total length about 11-0 inches; culmen 1-25; wing 5-1; tail 4-8 ; tarsus 1*75. Hab. Five-Finger Mts., interior of Hainan. 75. *GARRULAX SCHMACKERI. Garrulax moniliger, Styan (nee Hodgs.), Ibis, 1893, p. 427. Garrulax schmackeri, Hartl. Abh. nat. Ver. Bremen, xiv. p. 349 (1898). This species evidently belongs to the more slender-billed group and is closely allied to G. moniliger (Hodgs.), having the ear-coverts similarly coloured. It is, however, an altogether smaller bird and may be at once distinguished by the wide bright fulvous tips to the tail-feathers. The adult has the base of the fore-neck tinged with buff, while in a quite young bird this part is pure white ; in other'respects the plumage of the young bird does not differ from that of the adult. This species is new to the British Museum Collection. G.schmackeri: culm. 1*05 in.; wing 4*2-4-3 ; tail 4*5; tarsus 1'5. G. moniliger: „ 1*2 in.; „ 4-8-5-0; „ 4-9; „ 1*7. Interior of South-west Hainan (Styan Sr Hartlaub). 76. *DRYONASTES CASTANOTIS. Dryonastes castanotis, Grant, Ibis, 1899, p. 584. This very distinct species is perhaps most nearly allied to D. rufi-collis from India. The general colour above is slate-grey, tinged with greenish on |
