27. Ptilinopus solomonensis speciosus Schleg. 



Upper part of breast-baud yellow, lower white, forehead green, but lores 

 purple ; abdomeu ])ale lilac-mauve. 



Northern islands of Geelviuk Bay, Mafor, Jobi, and Traitor's Island. 



Besides four tmiles and a young bird, without locality, we have before us the 

 following' !'.» specimens : — 



12 c? Mafor (Doherty coll.). 



2 ? Mafor (Doherty coll.). 



1 ? Marai, Jobi (Doherty coll.). 



!(?,!? Traitor's Island (Bruiju's hunters, per Guillemard). 



1 J, 1 ? Korrido (Bruijn coll.). 



ON THE "lONOTRERON" GROUP OF PTILINOPUS. 



The next section of Ptilinopus we have to deal with has been termed by Count 

 .Salvadori, in Vol. XXI. of the Oat. B. Brit. Mm., the Imiotreron group, but has 

 been raised to generic rank in Dr. Sharpe's new Iluml-list. It consists of the 

 following forms : — 



P. hyogaster (Temm.). Northern Moluccas. 



P. granuli/rons Hart. Obi Major. 



P. nanus (Temm.). New Guinea and West Papuan Islands. 



P. pectoralis (Wagl.). AVest New Guinea and adjoining islands. 



P. salvadorii Rothsch. Jobi. 



P. viridis (L.). Southern Moluccas and South-East Islands. 



P. musschenbroeki Schl. Islands in Geelviuk Bay, and perhaps parts of 

 AVestern New Guinea. 



P. lewisi'R.&mn. Solomou Islands (Guadalcauar ?Shortlands). 



P. vicina Hart. D'Entrecasteaux group. 



P. eugeniac (Gould). Solomon Islands (Ugi), 



Before giving our enumeration of specimens, we think it necessary to e.xjilain 

 our great apparent inconsistency in treating all the forms of the lonotreron group 

 binomially, while we have named forms seemingly much more distinct trinomially. 

 The reason for this is that, although Count Salvadori has assigned very succinctly 

 separated localities to each of these forms, we have more than a suspicion that at 

 least two forms occur together on Jobi, and perhaps elsewhere also. If this is 

 the case, some of the forms in question would have to be treated as good species. 

 However, our knowledge is still too imperfect to warrant a definite statement as 

 to which forms are good species, and which subsjiecies. Therefore we are forced 

 to defer our final judgment about the affinities of these forms for the present. 



28. Ptilinopus nanus (Temm.). 



We have six specimens of this very distinct species from Mt. Gayata, the Aroa 

 River, and the highlands between the rivers Laroki and Vauapa, all collected by 

 Weiske. Three are males and X\^m(i females.
