Of T. minor T have examined no specimen, and therefore rely wholly on 

 Spencer's description. From this description the specific characters may be 

 summai'ized as follows: 



External Characters. Size small, head and body length being 200 mm. 

 and upwards. General body colour as in T. htgotis, but somewhat darker. 

 Manus white. Pes white above; dark in the posterior two-thirds below. Tail 

 with the black portion longer than the white portion. 



Cranial Characters. Skull small ; basal length 60 mm. or more. Muscular 

 crests and ridges very feebly marked, the skull being light and delicate in build. 

 Posterior (molar) portion of the palate slightly rounded. Molars in slightly 

 curved rows. The posterior end of the palate extends well behind the last molar 

 tooth. Posterior palatine vacuities from about the central point of the middle 

 premolar to the second molar (in figure) or to the third molar (in description). 

 The nasal bones at their posterior ends fall short of the line joining the lachrymal 

 foramina by about ") mm. See figs. 355 and 357. 



Dental Characters. Molars small. Considerable spaces between the 

 lingual margins of adjacent teeth. From the point of the canine to the back of 

 M^ is a distance of 28 mm. 



The type specimens came from the sandhills about forty miles to the north- 

 east of Charlotte Waters, in Northern Territory. The native name is "I'^rpila."
