(wings, tail) and somewhat smaller glossy spangles on the breast, from D. honieensis 

 in having a longer bill and longer tail. Measurements will be given below. As it 

 has no name, I distinguish it as 



Dicrurus suluensis sp. nov. 



Type: " Maimbun, Sulu, 23. iv. 1883. Length, 28 em. ; iris red-bro\ni ; bill and 

 feet black." Dr. H. Guillemard coll. (Mus. Tring). 



From D. borneensis our D. jentincki differs in its larger bill and wing and larger 

 spangles on the chest, while the tail seems to be of equal length. 



D. sitmalrensis is considerably smaller than D. jentincki, also more purplish 

 below. 



D. viridinitens Salvad. from Si Oban, ]\Ientawei grouji, west of Sumatra, of which 

 we have a type (specimen '• h " of the author's list. p. .594. Ann. ^Jus. Civ. Genova 

 XXXIV, 1895), is alarmingly near, and differs almo.st only in being smaller, while the 

 pectoral spangles seem to be larger. 



Dicrnrns de'iisus from Timor and D. I,-ilhni from Tenimber differ in having 

 larger bills and very much longer tails. 



It has been said (Salvad., Orn. Papiicis. e Molacc. II p. 174) that the form from 

 Obi Major, Moluccas, is the same as that from Sula, i.e. D. pectoralis. This is not 

 the case, as it is totally different; and never could the celebrated author of the 

 Ornitolofpo. Papunsia have come to his conclusion if he had been able to compare 

 specimens of both species. The Obi Major bird is much larger, has a longer and 

 higher bill, larger feet, longer wing and longer tail than D. pectoralis, and its iris 

 is brown, not crimson. I name it. in honour of my dead friend Doheity, who sent 

 us a series from (Jbi : 



Dicrurus dohertyi sp. nov. 

 This D. dohertyi is nearest to D. mer/nloi-nis of the Key Islands, but has not such 

 a long tail and not such a higli, arched beak as I), mei/alornis. (See measurements 

 below.)
