NEW AND INTERESTING MAMMALS 
OF THE DUTCH NEW-GUINEA-EXPEDITION 
TO THE SNOW-MOUNTAINS

Dr. F. A. JENTINK.

Phalanger gymnotis Peters et Doria. 
N° 277. Old 57. Regen-eiland, September 30, 1909 (skin with skeleton). 
N° 439. Very old Q. Alkmaar, January 29, 1910 (skin with skeleton).

Mus. Civ. Gen. VII) and at the same time the only known 
individual, has been a puzzle to all students of the Pha- 
langer-group. It therefore is of the highest interest that I 
found in the Lorentz-collection the three above mentioned 
specimens, prima facie distinct from. all hitherto seen in- 
dividuals of the orientalis-group, but at the same time ex- 
actly agreeing with gymnotis Peters et Doria. During the past 
summer I could study the type in the Genoa Museum, by

brought over from New-Guinea to the Arou-islands, so
