species Dr. Collott referred the examples collected liy Dr. Dahl. Not knowing 

 of any bandicoot of this type from North Australia in 1»88, I placed aierati/x as a 

 synonym of ?nacrufa in the Catalogue of Jlarsupials, but I now owe to the kindness 

 of Mr. E. R. Waite the measurements of the typical sknll preserved in the Macleay 

 Museum at Sydney, and these show that it belongs to the o/tfu'da group. The 

 following are the most important measurements of Dr. Ramsay's type, as sent 

 by Mr. Waite : — 



Greatest breadth of skull 23-5 : nasals 19-2 x 4-0 ; palate, length 281, breadth 

 outside ?«' 14-4, inside ?«^ 9-ii ; palatal foramen 5-4 ; basi-faeial axis 39-0 ; teeth, 

 canine to m* 19'(), length of/*' '2-2, molars ' ' S-7. 



These measures correspond closely with some of the smaller examples of the 

 present series, so that, in the absence of topotypes, it seems advisable to use 

 Dr. Ramsay's name. The small species from Barrow Island differs from these 

 sj)ecimeus by the smaller size of its bullae. 



The young skin from Victoria River, Northern Territory, presented by 

 Dr. J. R. Elsey in 1857, and referred in the catalogue to /'. macrura (specimen e) 

 proves on the extraction of its skull to be an example of the present species. 



P. (lurata, besides its cous]iicuonsly smaller size, is of a somewhat richer and 

 more fulvous colour than P. macrura.

One without label. 



General characters and appearance of the true Ph. penicillata, but smaller, 

 paler and with certain tooth differences. 



Size markedly less than in penicillata, as shown by the skull dimensions. 

 General colour above "smoke-grey" (Ridgway), therefore considerably paler than the 

 dark cinereous grey of penicillata. Under-surface dull whitish, not sharply defined 

 laterally ; the hairs mostly grey at their bases. Outer side of limbs grey, like 

 flanks; inner side whitish, like belly ; upper surface of hands and feet white, 

 with an occasional slight encroachment of brown on to the metapodials. Tail drab, 

 grey or brownish grey for about two inches at its base, the remainder broadly tufted 

 with black. 



Skull very hke that of penicillata, though markedly smaller ; nasals rather 

 broader in proportion, supraorbital edges more strongly ridged ; bullae smaller. 



Teetk : Incisors less disproportionate than in penicillata ; /' rather smaller, and 

 i ' but little larger than i ' and ;' * ; the enamel-covered portion of / ' is only about 

 1-2 mm. in vertical diameter, as compared with about 2 mm. Similarly below the 

 crown of the anterior incisor only measures about I'o mm. horizontally, as against 

 2-3. Last lower premolar little or not smaller than the first, while it is con- 

 spicuously smaller in Ph. penicillata. 



Dimensions of the type, measured in skin : — 



Head and body, 200 ; tail, 180 ; with hairs, 205 ; hindfoot, 32 mm. Skull (of 

 Dr. Elsey's specimen) : basal length, 42 ; zygomatic breadth, 27'5 ; nasals.
