and square or rounded, as in many forms ; or much abbreviated, as 

 in Gicinmirus. Astrapia stephaniae has the two median rectrices 

 concave and decurved over; those feathers in the males oi Paradisea, 

 Cicinimrus, DiphyUodes, Scldegelia, Paradisornis, and Uranornis 

 exhibiting more or less wire-like shafts, which terminate in large 

 racquets in Cicinnuvus, smaller discs in, Paradisontis. They are 

 broader, convex above, wavy, and horny in Uranornis, and are 

 curled outwardly in DiphyUodes and Schlegelia, while they cross 

 each other twice in the last, but once in Cicinnurus. Pterido- 

 phova has an extraordinary streamer behind each eye. That these 

 however, are by no means the only remarkable developments, will 

 be seen from the following descriptions of the most striking species, 

 all of which are confined to Papuasia and Australia, except the 

 Moluccan genera Semioptera and Lycocorax. The feathering often 

 extends over part of the bill. 



Manucodia and Phonygammus are the only Passerine birds 

 known to have a convoluted trachea.^ 



Ptilorhis paradisea, the Eifleman-bird,""^ is velvety-black with 

 a purple gloss, having the head, throat, and median rectrices 

 green, the abdomen bronzy; the crown - feathers are scale -like, 

 and the silky flank-plumes considerably elongated. P. niagnijica 

 is somewhat similarly coloured, with a stiff pectoral sliield of 

 metallic green ; lantliothorax and Paryphepliorus, with erectile 

 nuchal collars, are near allies. Seleucides ignotus the Twelve- 

 wired Bird of Paradise, which has six long, recurved and filiform 

 appendages to the lax, projecting feathers of each side, is black, 

 with purplish head, wings, and tail, bronzy back, broad erectile 

 breast-plumes margined with emerald, yellow sides and belly. 

 Drepanornis alhertisi is rufous-brown, with green throat and ante- 

 ocular region, white Ijelly and dusky breast ; the sides of the last 

 exhibit dark-edged bronzy plumes, which can be expanded like a 

 fan, succeeded by long grey decomposed feathers with lilac margins ; 

 and small Iduisli tufts surmount the bare orbits and post- 

 ocular region. Falcinellus sjMciosus is black with rainbow-like 

 reflexions ; the broad plumes of the sides of the upper breast 

 being banded with metallic blue and green, and having wide tips 

 which open upwards into a fan ; while the long pointed flank- 

 feathers compose similarly coloured tufts. Astrapia nigra, the
