104; new ed., 1863, 92 (misprint). 
Type: Perameles lagotis Reid, from Swan River, Western Australia. 
The original account of the genus appeared in the Proceedings of the Zoological 
Society of London for 1838, the name only in the Athenzeum. For this 
reason Thylacomys is treated as a nomen nudum in 1858 and dates from Blyth’s 
Cuvier, 1840. The form Thalacomys, although an obvious misprint, is adopted 
as the original spelling by Thomas ( Ann. & Mag. Nat. Hist., Feb., 1900, 223). 
This name antedates Paragalia Gray, 1841. 
Thylacomys: 60Aakos, pouch; “0s, mouse—in allusion to the pouch, which is

Ow.), from a recently opened cave near ‘ Wellington Cave’ locality, New South 
Wales. [Publication deferred. ]”’
