NOVITATES ZOOLOQICAE XXII. 1915. 51 



S, Avera, Aroa River, 5. xi. 1903. A. S. Meek coll. " Iris dark fawn ; bill 

 dark horn-colonr, lighter at tip ; feet pale dirty yellow." 



18. Megatriorchis doriae Salvad. & d'Alb. 



Mega trio rcli is iloriue Salvador! and d'Albertis, Ami. ilus. Civ. Gen. vii. p. 805 (1875— S.E. 

 New Guinea). 



This genus was separated on account of its short ronnded wings, the very small 

 difference in length between primaries and secondaries, and the long tail (in the 

 original diagnosis is a misprint, " remigibas primaries paulo brevioribus " instead 

 of " panlo longioribus " ; this is evident from a look at the bird and from Salvador!, 

 Orn. Pap. i. p. 42). 



Later on Sharpe united Megatriorchis with Erythrotriorcki.i, bnt we cannot 

 accept this alteration ; it was done on the strength of a bird which Sharpe wrongly 

 identified with M. doriae, and which we were obliged to describe as a new species. 

 In the typical Erythrotriorchis (type E. radiatus) the wings are much longer, the 

 distance between the longest primaries and secondaries considerable, viz. 11-13*5 

 cm., as against 25-35 mm. ! in Megatriorchis. The tail in Erythrotriorchis is 

 shorter and more even than in Megatriorchis, so that the bird has altogether a very 

 different appearance. 



Of M. doriae we have so far the following skins : 



1, Triton Bay, 25. vii. 1896. Cayley Webster coll. 



1 jun., German New Guinea. Cotton and Webster coll. 



1 ? ad., Mts. inland of Huon Gulf, German New Guinea. Purchased from 

 Schneider. 



1 cj ad., Astrolabe Bay. C. Wahnes coll. 



? Kumusi River, British New Guinea, 5. viii. 1907. A. S. Meek coll. 



Needless to say, the females are larger than the males : wing ? 350, i 285- 

 92 mm. 



19. Accipiter (Astur) eudiabolus Rothsch. & Hart. 



Accipilcr eitdiahohis Rotlischild & Hartert, Bull. B. O. Club, xxxv. p. 8 (October 1914 — 

 Babooni, British New Guinea). 



Ad., Babooni, 3000 ft., September 1903. H. C. Pratt coll. (type). 

 20. Accipiter novaehoUandiae leucosomus (Sharpe). 



Astur norae-hoUandiae subsp. a. A. leucosomus Sharpe, Cat. B. Brit. ilus. i. p. 119 (1874 — "New 

 Guinea and adjacent islands). 



Though the difference in size is enormous, there is no other difference between 

 the larger Australian white Goshawk and the smaller Papuan race. The whole 

 plumage is snow-white ; the iris and cere yellow ; bill horn-black ; feet yellow. 

 Wings of males 210-212, females 242-252 mm,, against 251-272 (males) and 

 293-308 (females) in A. novaehoUandiae novaehollMidiae.
