back. Heller has described them as a new species, D. Hageni, in Abh. und Ber. d. K. Zool. 

 und Anthr. Ethn. Muséum, Dresden, 1896/97, Bd. VI, N°. 8, p. 7. Notwithstanding it is now 

 ten years since the species has been discovered, nobody has collected other spécimens; now it 

 therefore is very interesting that the Humboldt Bay expédition had the good luck to 

 shoot two other spécimens, females, one at the Sentani-Lake, June 21. 1903, the other at the 

 Humboldt Bay, July S. 1903. As Heller observed the female is much smaller than the 

 maie; of our largest female, the Humboldt Bay-specimen, the measurements are the fol- 

 io wing : 



head and body 5S0 mm. 



tail 355 



ear 45 



eye to nose 55 



ear to nose 10S 



hind foot 121 



hind foot with nail 135 



Thèse measurements hâve been taken from the spécimen when in alcohol. 



The dimensions of the skull are : 



condylo-basilar length 105 mm.

The skeletons présent 13 ribs, 13 thorac, 6 lumbar, 2 sacral and 21 caudal vertebrae. 



I'add to Heller's description of the color of this so extremely soft-haired animal, that the top ofthe 

 tail is white. 



The tail itself needs some closer inspection ; this organ is clad with scales solely towards 

 the end, where the hairs grow shorter and shorter so that the extrême tip is scaled ail round ; 

 between thèse scales a few very short scattered hairs; like in Dendrolagiis there is a bald 

 spot just beyond the base of the tail, however as the proximal part of the tail is not scaly 

 but only wrinkled, so this large and broad naked spot also has a wrinkled apparance (fig. 10). 

 The hairs along the upperpart ofthe tail look like an elevated crest, a resuit ofthe gutterlike 

 impression along the sides of the tail, so that the latter by cross-section shows the form of 

 an hour-glass; the hairs of the crest along the tail are longer and darker colored than those 

 on its sides and base. 



19. Halmaturus agilis Gould. 



Three young individuals from Merauke belong apparently to H. agilis. 

 Skeleton with 16 ribs, 6 lumbares, 2 sacrales and 26 caudales. 



20. Perameles moresbyensis Ramsay. 



One adult maie and two ditto females hâve been collected at Merauke.
