1906.] MAMMALS FROM NORTHERN AUSTRALIA. 537 



higrami, after Sir William Ingram, thougli a new species^ of Mus 

 {M.forresti) has such peculiarities of dentition that their study 

 has resulted in a recent rearrangement of the murine genera of 

 Australia. 



1. Nyctophilus geoffroyi Leach. 



c? . Alexandria. 

 Forearm 35 mm. 



2. Chalinolobus gouldi Gray. 



c^. 122, 127. $. 125, 128. Bluff Hole, Alexandria, 21-24 

 May, 1905. 



3. SCOTEINUS GREYI Gould. 



Ten specimens. Alexandria. 



4. Nyctinomus plicatus colonicus, subsp. n. 



J.Alexandria. B.M. No. 6.3.9.16. Type. 



Similar in all essential particulars to the true Indian plicattos, 

 but rather larger in body and limb dimensions, and markedly 

 larger in the skull, the cranial crests, sagittal and lambdoid, very 

 well developed. 



Dimensions of the type, measured on the spirit-specimen : — 



Forearm 50 mm. 



Head and body 67 mm. ; tail 42 ; ear 22 ; third finger, meta- 

 carpal 50, 1st phalanx 21, 2nd phalanx 22 ; lower leg 18. 



Skull — greatest length to occipital ci'est 22 ; basal length 17-7 ; 

 zygomatic breadth 13"5 ; mastoid breadth 12 ; palate length 8'7 ; 

 front of upper canine to back of m^ 8 ; front of lower canine to 

 back of mg 9. 



Hab. and Type as above. 



A South-Australian specimen of JV. plicatus received from 

 Prof. Leche in 1890 also belongs to this larger race. On the 

 other hand, examples from New Guinea and the Fiji Islands 

 correspond in size with Javan and Indian specimens, 



5. Canis dingo Blum. 



Skin and two skulls. Alexandria. 



6. Mus villosissimus Waite. 

 M. longijoilis Gould nee Waterh. 



S. 86, 87, 89, 101, 106, 108, 139, 140, 142. $. 114, 137, 

 141, 143. Alexandria. 



S . 145, 186, 187. 2 . 147, 148, 184, 185. S.W. of Alroy. 



This species is so common at the station as to be a serious 

 pest. 



The type locality of Gould's M. longynlis was the Victoria 

 River, about 400 miles to the west of Alexandiia, but in the 

 same faunal area.
