island of Jobie, eight species of this genus dwell, viz. Pt. superbus, 

 Pt. coronulatus, Pt. geminus, Pt. aurantiifrons, Pt. perlatus, Pt. 

 strophium, Pt. puella, and Pt. jobiensis. The small island of 

 Ansus, to the south of Jobie, contains also one species, Pt. geminus, 

 being the only one out of those found upon its great neighbour. 

 Meosnoum or Misnomin, to the west of Jobie, also contains one 

 species found on that island, Pt. strophium. On the island of 

 Korido, or Sook, the most northern of those in this bay, two species 

 have been procured, Pt. pectoralis and Pt. speciosus. Mansinam, 

 the last island in this bay from which any species of Ptilopus is 

 known to come, contains one species, the Pt. humeralis. It will thus 

 be seen that, so far as we are able to determine from our mate- 

 rial, in the Bay of Geelvinck, Jobie is the central or starting- 

 point of the members of this genus. The two small islands lying 

 near are only detached portions of Jobie, each containing one species 

 found on the last, but none peculiar to themselves. On the other 

 hand the islands of Korido and Mafor only have one species in 

 common with Jobie, viz. Pt. superbus, found on Korido, while on 

 Mafor Pt. pectoralis and Pt. geelvinkianus are met with, the 

 last-named being also a native of Meosnoum. The relationship of 

 these islands, so far as regards this genus, are nearer to the western 

 shores of the bay than to Jobie. Turning now to the mainland, at 

 Andai and Dorey five species are found — Pt. pulchellus, Pt. pecto- 

 ralis, Pt. puella, Pt. geminus, and Pt. perlatus ; while on Mount 

 Arfak Pt. superbus, Pt. bellus, Pt. iozonus, Pt. aurantiifrons, and 

 Pt. ornatus have been obtained. At Amberbaki, on the north 

 coast, five species have been procured, viz. Pt. pulchellus, Pt. super- 

 bus, Pt. perlatus, Pt. pectoralis, and Pt. bellus ; while at Sorong 

 Pt. trigeminus, Pt. humeralis, Pt. coronulatus, and Pt. prasi- 

 norrhous have been met with. At Triton Bay Pt. nanus has been 

 obtained ; and at Mount Epa, in the south of New Guinea, the 

 small race of Pt. magnificus, called puella, is found. These are all 

 that are as yet known to come from the mainland of New Guinea ; 

 but doubtless others of the described species, as well as those not 

 yet discovered, remain to be obtained among the dense forests of 

 this singular country. Passing now to the western islands of the 

 Papuan group, the most northerly is Waigiou, which contains five 

 species — Pt. superbus, Pt. pulchellus, Pt. prasinorrhous, Pt. puella, 

 and Pt. pectoralis, this last being also found upon the near-lying 

 small islands of Gagie and Giebeh, while Pt. puella is also met 

 with on Ghemien. Batanta has four, viz. Pt. aurantiifrons, Pt. 

 superbus, Pt. pectoralis, and Pt. prasinorrhous ; while Salwatty pos- 

 sesses all these (excepting Pt. pectoralis) and also Pt. coronulatus, 

 Pt. trigeminus, Pt. humeralis, Pt. pulchellus, Pt. perlatus, and Pt. 

 puella. Mysol, to the south-west of Salwatty, contains seven 

 species, viz. Pt. prasinorrhous, Pt. superbus, Pt. aurantiifrons, Pt. 

 pulchellus, Pt. puella, Pt. pectoralis, and Pt. nanus. All of these 

 save the last two are found upon Salwatty. Far to the south of this 

 last-named island we reach the most southern ones of the group, viz. 

 Arou, with seven species (Pt. coronulatus, Pt. superbus, Pt. iozonus,
