" ON THE NEW-GUINEA MAMMALS. 197 



Catalogue; head and body 106 mm., tail 153 mm. 



Loria collected specimens at Gerekanumu, Astrolabe- 

 Mountains. 



95. Acrobates pulchellus Rothschild. 



This species differs from A. pygmaeus (Australia, N. 

 S. Wales) in its more purplish-brown colour, its broader 

 and more robust head, much shorter tail and compara- 

 tively smaller body; it is based upon a single specimen 

 from one of the small islands in Northern Dutch New- 

 Guinea (P. Z. S. L. 1892, p. 546). 



96. Halmaturus agilis Gould. 



If Thomas is right in uniting H. papuanus Peters et 

 Doria (Ann. Mus. Genova, 1875, p. 544) with H. agilis, 

 then agilis inhabits New-Guinea; Thomas however remar- 

 ked (Catalogue, 1888, p. 44) that the Papuan-specimens 

 appear to be somewhat smaller and to have longer fur and 

 better defined markings than their north-Australian reprensen- 

 tatives. In the British-Museum are specimens by Broad- 

 bent from Port- Moresby, British New-Guinea, in the 

 Leyden-Museum is a specimen from the Fly-river, mean- 

 while the type-specimen in the Genoa-Museum is from 

 Roro or Yule-island, South-East New-Guinea, by d'Albertis 

 and Tomasinelli. Probably Ramsay's crassipes from Port- 

 Moresby belongs to this species. Loria procured specimens 

 for the Genoa-Museum at Waikunina and Aroma, east- 

 wards from the mouth of the Kemp Welch-river. 



97. Thylogale Broivni Ramsay. 



Thomas (Catalogue, 1888, p. 51) stated that this 

 species is exceedingly similar to Brunii (from the Arou- 

 and Key-islands) in all characters. Indeed it seems that 

 the difference solely is a slight modification of colour.
