NISUS RUFITORQüES AND N PÜLIOCEPHALUS. 3 



in the island of Guebeh. Two of these , male and female , 

 hardly differ in color from the adult female of the 

 Fidji islands. The second old female is , on the con- 

 trary a much larger and stouter bird; the vinous color 

 is much deeper passing almost to rufous, and intercep- 

 ted by numerous- narrow and pale bars of a grayish white 

 color. 



There is no difference between this latter specimen and 

 an adult female killed in Obi-island. 



We observe exactly the same system of coloration in 

 four adult specimens collected in the island of Morotay, 

 but in an adult male shot in the same island, the vinous 

 tint is strongly inclining to rufous, and Avithout any trace 

 of clear bars. It is almost superflous to state , that 

 Mr. Wallace established his Accipiter Muelleri on speci- 

 mens of Nisus rufitorques of Morotay -island. 



Ten adult individuals shot in the isle of Ternate are 

 like those of Morotay, but the light cross bars are in 

 general less conspicous and entirely wanting in three of the 

 specimens. Besides these individuals we received from this 

 island two specimens of the dark variety living in Hal- 

 mahera. 



Neither is there any decided difference between four 

 adult specimens of the island of Batjan and those of 

 Morotay, but a fifth adult female of Batjan shows the 

 coloration of the black variety common in Halmahera. 



Five of our adult specimens of Halmahera can in no 

 way be distinguished from those of Morotay, except that 

 four of them have the light cross bars of the lower parts 

 more pronounced ; but in the fifth specimen these bars 

 are entirely wanting. There exists , however , in the island 

 of Halmahera , besides the specimens with the usual colo- 

 ration , others that form a dark variety similar to what 

 is observed in the common hawk (Falco communis.) Their 

 upper parts are of a darker slate color and the vinous 

 collar of the neck is entirely wanting. The color of the lo- 

 werparts is much deeper , and every where , that is to
