30. Edolioaoma dispar Salrad. 

 One male from Larat. Agrees with specimens from Key, Dammer and l?anda. 



31. Artamus leucorhynchus musschenbroeki A. i'. Moycr. 



I am not proj)ared to unite the Timorlant Artamus straightway with A. leuco- 

 rhynchus. It is true that the alleged white tips to the rcctrices are not a distin- 

 tingnishing feature. They are found in many iutlividnals from other countries, and 

 most regular and constant in the typical leiicorhijiichus from tlic Philijipines. The 

 darker colour of musschenbroeki is evident in all Timorlaut examples, though it can 

 occasionally, after much search, be matched in specimens from other places — for 

 example from the Moluccas. The rather large, high bill, however, seems a good 

 distinguishing character. It is developed in the whole series (ten from Larat) 

 before me, and there are only a few from other places (Alor and South Flores) that 

 have equally high bills. Altogether the size of the bill varies considerably in all 

 localities ; but it is quite possible that there is a large-billed race on some of the 

 eastern islands. In that case there would be three races, namely : 



Artamus leucorhynchus leucorhynchus : Philippines and must of the eastern 

 islands. (Bill median.) 



Artamus leucorhynchus musschenbroeki : Tenimber Islands, and perhaps some 

 other islands. (Bill large, higher.) 



Artamus leucorhynchus Icucopygialis : North Australia, and perhaps parts of 

 Southern New Guinea. (Bill smaller.) This is the form wliich I named ,1. leuc. 

 parvirostris, but I think Gould's name leucopygialis should be used for it. (< 'f. also 

 Zeitschr.f. ges. Orn. III. p. IS, 1880.) 



32. Dicrurus ktlhni nov. 



The Timorlaut Drongo has been hitherto erroneously united with Dicrurus 

 bracteatus of New Guinea and Australia. It differs widely from bractentus, having 

 a much more curved and less ridged bill, longer tail, and no large, dull, glossless 

 black unspotted area on the mantle. D. kilhni, as I name the Tenimber form, is, 

 in fact, more closely allied to the Key form {D. megalornis), from whicli it differs 

 merely by its more curved, less thick and high beak, and smaller size. Its iris is 

 red, feet and bill black. The wing measures in the males 155 to 103 mm., in the 

 females 140 to 145 mm. ; the tail about 105 mm., ciilraen (over the curve) about 

 143 mm., metatarsus 20 to 28 mm. 



Mr. H. Kiihn sent us six skins from Larat, most of them, unfortunately, 

 much worn. 



This form and a number of others will, of course, better be treated as subspecies 

 of one species ; but I have not time at present to work out the relations of these 

 forms to each other. 



33. Pachycephala fuscoflava Scl. 



A beautiful series from Larat and Yanidena. Sclater at first figured and described 

 only a young uwle und female. The adult male is below entirely yellow, with a
