144 On Bandicoots allied to Pt'ianK'le.s boiigainvillei. 



the baiKlicoots of this group to two forms — P. hougainvillei 

 ti/picn^ of Western Australia, and P. b.fasciata, of fcjouth 

 Australia and New South Wales. Since then the arrival of 

 specimens from the islands of Shark's Bay — the type-locality 

 ol bofif/aiuvil/ei — has shown that that animal is smalh-r tiian 

 the ordinary W. -Australian striped bandicoot, and that the 

 latter should have Wagner's name of mt/nsuros — or, rather, 

 vit/osura — applied to it, as indicated in lii06 *. 



On now examining; the specimens from S. Australia and 

 New South Wales, 1 find that these are distinguishable from 

 t-ach other, the teeth of the latter being much larger than 

 those ot the former, so that instea<l of the two forms — " bou- 

 paiiivil/ei^^ ([)roperly mijosura) a.\\i\ fasciata, — as recognized 

 in the Catalogue, there are really tour. 



After selecting specimen a ot fasciatn^ from the Liverpool 

 Plains (B.M. no. 41.1178), as its lectotype, the names, 

 characters, and localities of the four forms would appear to 

 be as follows : — 



A. Size small; skull of male only about 57 



mm. in loiiirth ; bullje very small ; ins^-^

B. Size large; skull of male over 00 mm. ; 



bullae larger. 



a. Teetb smaller and lijrbter. Muzzle 



more slender. Ms^-^ about 10 mm.. . 2. P. mi/osura, Wagn. 

 «*. Dark bands comparatively indistinct, 



not crossing back. (\V. Australia.) '2 a. 1'. myosura mijusura. 

 h^. Dark bands more distinct, perceptible 



across back. (S. Australia.) '2h. 1'. m. uotina, subsp. n. 



b. Teeth larger and beavier. Muzzle more 



conical. J/a1-3 about 11 mm. (New 



South AVales.) 3. P.fasciata, Gray. 



Perarneles myosura notiiia, subsp. n. 



External characters almost exactly as in P.fasciata, as 

 described in the Catalogue and as figured by Gould; but 

 skull, us in viyosura, with more slender muzzle and smaller 

 teeth.
