mountains in the interior reach a height of about 5000 ft. It was for a long time 

 uninhabited, but within the last ten years some villages have sprung up. 



Though I have in all more important cases adhered to the system of qiioting the 

 original reference and habitat in full, I have sometimes disregarded it in order to 



save time. 



The systematic arrangement of the following list is that of Salvadori's " Ornito- 

 logia della I'apuasia," in order to facilitate comparison with that work. 



1. Cuncuma leucogaster (Gui,). 



.Mr. l.ucas brought with him several specimens, lie quotes as native names 

 " Koheba gunong " and '' Koheba laut." Bernstein had obtained it already on Obi, 

 also Guillemard {P. Z. S. 188;3. p. 562). 



2. Haliastur Indus girrenera (A'ieill.). 



Native name, according to Lucas, is " Koheba." 



Guillemard {I.e.) mentions Haliastur intermedius, but I am sure the birds fi-om 

 Obi must all belong to tjiii-enera. 



3. Baza subcristata rufa Schleg. 



Baza rufa Schlegel, For/. Xederl. Ind., Valkvog. pp. 41. 78 (1866 : " groep van 

 Halmahera). 



We ha\e a s|)ecimen from Mr. Lucas, obtained on Obi between October and 

 December 1898. The native name is, according to Lucas, also " Koheba." The 01ii 

 specimen agrees with others from Batjau and Halmahera. (Cf. Nov. ZooL. VIII. 

 1901. i>. 379.) 



4. Tinnunculus moluccensis Bp. 



Tinnuncvlus molucoetms Bp., Consp. Av. i. 1850. ]i. 27 (e.x Hombron et Jacq., 

 Amboina!); Guillemard, P. Z. S. 1885. p. 526 (Obi). 



Tinmincidus moluccensis orientalis Meyer & Wiglesw., B. Celebes i. 1898. 

 p. 79 (Halmahera group). 



Guillemard and Lucas obtained specimens on Obi Major. 



According to Meyer and \^'iglesworth the form from the Halmahera group — 

 to which Obi belongs more or less — is to be separated from that of the Southern 

 Moluccas (Amboina, Burn, Ceram, Goram, Peling). The material which I have been 

 able to examine so far does not justify this separation. I can see two ver}' distinct 

 races- — namely, a darker form, with more brown cheeks and ear-coverts, darker under 

 wing-coverts and lighter under surface, inhabiting the Moluccas, and a lighter one, 

 witii more greyish cheeks and ear-coverts, much wliite.r under wing-coverts and 

 ligiiter underside, inhabiting Celebes and the Lesser Suuda Islands to Kaugcau and 

 Java. It is true that some few specimens from the Southern Moluccas are somewhat 

 intermediate, but the majority before me are exactly like those from the Northern 

 Moluccas, and all agree best with the latter. Moreover, some examples from the 

 Moluccas are variable and lighter than usual. Tiie form from Amboina is the tyjiical 

 vwlnccetwis, and I umsf unquestionably unite with it the orientalis of iMeyer 

 and W'iglesworth, while certainly recognising T. raolucc. occidentalia as distinct.
