Bii-ds of Celebes: Laniidae. 399 



There is some uncertainty about the locality whence the type of P. griseo- 

 nuta, an immature male, came, for the label, as Count Salvador! points out, 

 is marked "Ceram?" and, above this, "Mysol?". The locality Mysol is accepted 

 without] query by Gadow' and by Heine & Reichenow for a specimen in 

 the Heine Museum. For the present both islands should be regarded as doubtful, 

 but we believe, with Salvadori, that Ceram will prove to be the correct 

 habitat of the species.

"Kokijak" ($) Banggai, Nat. Coll. 



Adult male. Head and face black, passing round the jugulum as a narrow collar; chin, 

 throat and submalar region white; upper parts yellow-olive; tail and remiges 

 black, the secondaries broadly bordered with the colour of the upper parts, the 

 primaries with grej-er oHve; extreme tip of tail brown; under parts, a collar 

 passing round the hind neck, and metacarpal edge gamboge-yellow; inner 

 under wing-coverts whiter; remiges below dusky, whitish where they rest upon 

 the body: bill black; legs and feet dark ([$] ad. PeHng Id. V.— VHI. 95: Nat. Coll. — 

 14555). 



Female. Above, including the tail, and the remiges externally olive-brown, remiges in- 

 ternally dusky; head above dark grey-olive, lores whiter, ear-coverts more as the 

 back; chin and throat impure white; a faint brownish band across the breast; 

 under parts rufescent-yellowish, clearing mesially into purer yellow; legs and feet 

 brown, claws paler; bill blackish [[Q] Banggai Id. V.— Vm. 95: Nat. Coll. — 

 14683). 



Measurements. "Wing (males) 90 — 93 mm, (females) ca. 85; tail ca. 71; tarsus ca. 21; bill 

 from nostril ca. 1 1 . 



Distribution. Sula Islands — (Allen 1), Sula Besi (Bernstein b 1); Peling and Banggai 

 (Nat. Coll.); Buru (Wallace 1, 2, Bruijn 5, a 1). 



Mr. Wallace (2) remarks that his Buru specimens "have a more yellow 

 tinge on the back, and the black pectoral band is generally broader than in 

 those from Sula". In 1881 (a 1) Count Salvadori united the Buru bird with 

 P. macrorhyncha Strickl. of Ceram and Amboina. In his valuable key (7) to 

 the four closely allied forms of the group composed of P. melanura, clio, macro- 

 rhyncha and ohiensis Dr. Sharp e has unfortunately neglected to define the geo- 

 graphical limits of the species; and, as Count Salvadori at the time of writing
