35-0 centims., wing 16-8-17-4. tail 160-17-0, bill from gape 



3-6-3-9. 



Tliis species is most abunrlant in Batchian, but does not seem ever 

 to have been recorded from Ternate. 



40. DiCRUROPSis, sp. ? 



a. $ . Bisa I, Obi group. 



Iris brown ; bill and feet black. Length 31-8 centims., wing 16-0, 

 tail 14*5, bill from gape 3"5. 



I am unable to refer this bird with certainty to any species, but 

 am unwilling to add yet another species to the already somewhat 

 overburdened genus on the strength of a single example. It is quite 

 distinct from 1). atroccerulea, not only in the broader pectoral spots 

 but in its small size, and more especially in the possession of 

 metallic hackles at the sides of the neck. The only species of this 

 genus as yet recorded from the Obi group is D. pectoralis of 

 Wallace. In the latter, however, the pectoral spots are very much 

 larger and more conspicuous, and are greener in shade, while the 

 neck-hackles are also longer and larger. The head of the Obi bird 

 is without silky filaments, but this is the case in many examples of 

 D. pectoralis. '' It is worthy of remark that the iris was noted by 

 myself as brown.

a. 2 . Batchian. 



This bird occurs in Mr. Kettlewell's collection. As, however, 

 neither this genus nor Rhectesh^s been recorded from the Moluccas, 

 some doubt must exist as to the accuracy of the locality. It does 

 not differ in any way from specimens obtained from the island of 

 Batanta. 



42. Pachycephala mentalis. Wall. 

 Fachycephala mentalis, Salvad. op. cit. vol. ii. p. 216. 



a. S • Ternate. 



b. 2 • Batchian. 



Iris brown ; bill black ; feet brown.

 Pachycephala obiensis, Salvad. op. cit. vol. ii. p. 219. 



a. S • Bisa Island, Obi group. 



b. $ . Obi Major. 



Iris brown ; bill black ; feet in male pinkish grey, in female light 

 brown. Length 19-0 centims. ; wing 9-2-9-.5. 



The female differs from that of P. mentalis in being smaller and 

 bavins; the throat light fulvous-brown, not greyish white. In P. 

 mentalis the upper breast is brownish and the lower breast and 

 abdomen dull olive-yellow, while in the present species the whole 

 breast and abdomen are dull orange-yellow.
