 bills. Yonng apparently always black ! Ihib. : New Guinea, Sahvatti, Waigiii,

2. Cracticus quoyi ru/esce)is De Vis, Proc. Linn. Soc. JV. S. Walf.s vii. 

 J). 562. Typical locality : Queensland. Differs at a glance from C. q. quoyi by its 

 thinner, less swollen bill. Young evidently dimorphic : sometimes black, more 

 often brown above with rnsty bnff stripes, underside rusty buff. Femab's (r when 

 fully adnlt) also sometimes brown, but generally black. That the brown birds 

 moult into the black ones is shown by two specimens in tlie Tring collection.

3. Cracticus quoyi subsji. nov. ? It is surprising to lind that the Aru birds 

 do not at all agree with the New Guinea form, but are very closely allied to 

 C. q. tunneyi. Their bills seem, however, to be slightly shorter, and the wings 

 shorter. As we have ouly two unse.xed birds from Tapt. Webster, apparently 

 i and ? , and a female collected by Mr. Heiiiricli Kiihn, I am not naming this 

 form, which is intermediate between C. q. quoyi and C. quoyi tunneyi, but hope to 

 discuss it later, when more skins from the Am Islands are available. 



4. Cracticu.i quoyi tunneyi subsp. nov. Type : S ad.. Alligator Uiver, 

 25. ix. Ifl03 (No. 10113 Tnnney coll.). Named in honour of the collector, Mr. J. T. 

 Tunney. Differs from C. q. rufoscens in its much larger size : bill i ()5-5, ? 

 53 to 55; wing, S 205, ? 185 to 188 mm. — i.e. fully an inch longer than in 

 ('. q. rufe.'icens. I am uiiiible to say whether the yonng are black, rufous, or 

 black and rufons. 



Mr. Tnnney sent the following sj)ecimeus only :

2 ? ¥, Alligator River, about 16 and 35 miles from the coast, 25. ix. and 

 10. X. 1903 (Nos. 1001, 1002). 



Mr. Tunney says he shot these birds in mangrove swamps on tidal waters 

 near the coast, where he only saw this Cracticus. '' Iris dark brown, feet black."

Tliese specimens belong to the larger form, C. n. niqroqulari.^, the distribution 

 of which is peculiar, as it seems to occur in New South Wales and throughout West 

 Australia, and is only rej)laced by the smaller C. n. jjicatus in the Northern Territory 

 and in the northern portions of Queensland. Birds collected by Mr. Tom Carter 

 at Point Cloates are distinctly of the large form, while I consider all the North 

 Queensland examjiles, from Cedar Bay, Cooktown, etc., to be typical picatus.
