788 MESSES. O. THOMAS AND G. DOLLMAN ON [Nov. 3, 



Another characteristic of B. valhaUce is the presence of a con- 

 siderable glandular swelling on the calf of the hind limb ; in none 

 of the above-mentioned species does this occur ; it is, however, 

 conspicuous in the British species B. calamita. 



B. valhallce is capable of jumping along at a good j)ace, and is 

 very active in catching any insect, however fast ; I have frequently 

 seen them jump quite 6 inches from the ground to catch a moth 

 running up the side of their cage.

(Plate XLII.) 



After he had made the interesting collection of mammals from 

 Alexandria, North ein Territory, of which an account was given 

 two years ago *, Mr. W. Stalker was sent b}- the same generous 

 donors to Inkerman, their station on the Burdekin River, near 

 Townsville, in the southern part of Noi-th Queensland, and he 

 has there formed the very fine collection of which we now give a 

 list. 



This region was hithei'to almost entirely unrepresented in the 

 National Collection, such of the few Queensland specimens as we 

 possessed being either from the far north, on the Cape York 

 peninsula, or from near Brisbane ; and the j'l'esent collection 

 therefore, including as it does admirable series of all the local 

 mammals, is of exceeding value to the Museum, while its general 

 scientific interest also proves to be very great. 



A study of the collection shows clearly that this part of 

 Queensland belongs to the northern fauna, the species being all 

 either those of North Australia, or nearly related to them, while 

 such southern forms as are represented are generally subspeci- 

 fically separable from their allies of New South Wales and South 

 Queensland. The new Wallaby {Macro2nis tudahattts ingrami) 

 and the Water Eat {Hydromys chrysogasier regince) may be 

 cjuoted as instances of such subspecific diflferences ; while the 

 presence of Isoodon torostcs instead of obestdus, of Dasyurus hal- 

 lucatvs, Macrojnis agilis and many others, are evidence of the 

 essentially northern relations of the Townsville region. 



Altogether this is one of the most important Australian col- 

 lections that the Museum has ever received, and we are therefore 

 very deeply indebted to Sir Williana Ingram and the Hon. John 

 Forrest, the donors of this most valuable addition to our National 

 Collections.
