Molineux. The three subsequently received shortly afterwards, 

 as well as the last lot recently secured by Mr. Bishop during our 

 journey through the country, were also found on the Idracowra 

 Station. This is a large cattle-run comprising several hundred 

 square miles of country in the southern part of the Northern 

 Territory of South Australia, which lies immediately to the West 

 of the telegraph line between the Charlotte Waters and Alice 

 Springs Stations. The great dry watercourse of the Finke River, 

 which runs from N.W. to S.E., bounds the run for some eighty 

 miles on the North and North East. Its distance from Adelaide 

 is roughly speaking a thousand miles. Flats and sandhills of 

 red sand, more or less well covered with spinifex and acacias, 

 constitute a large portion of the country, and the rainfall is 

 inconsiderable. Curiously enough, all the specimens hitherto 

 received by me have been found within a circumscribed area, 

 four miles from the Idracowra Head Station, which is situated on 

 the Finke watercourse itself, and almost invariably amongst the 

 sandhills. I have it, however, on very fair authority, that the 

 animal has been seen on the Undoolya Station, which lies immedi- 

 ately South of the McDonnell Ranges, and that one also was 

 found drowned after heavy rain at Tempe Downs, a station 

 situated about 120 miles W.S.W. of Alice Springs. These 

 points will sufficiently define its range, so far as is known at 

 present. They do not appear to be very numerous. Very few 

 of the white men in the district had ever seen it, even though 

 constantly travelling, and not many of the natives whom I came 

 across recognised the well-executed coloured drawing I carried 

 with me. It must be remembered, however, that I did not pass 

 through the exact spot which so far appears to be its focus of 

 distribution. Nor did a very considerable reward, which I offered, 

 <;ause any specimens to be forthcoming between the first lot 

 received, over two years ago, and that recently secured during 

 my transcontinental trip. With few exceptions the animals have 

 been captured by the aboriginals, who, with their phenomenal 

 powers of tracking, follow up their traces until they are caught. 

 For this reason they can only be found with certainty after rain, 

 which sets the surface of the sand and enables it to retain tracks 

 that would immediately be obliterated when it is dry and loose. 

 Nor are they found except during Avarm weather. So that the 

 short period of semi-tropical summer rains appears to be the 

 favourable period for their capture. For this suitable combina- 

 tion of wet and warmth, Mr. Bishop had to wait three months 

 before he was able to get them, and in all cases they were found 

 during the day time. Perpetual burrowing seems to be the 

 characteristic feature of its life. Both Mr. Bishop and Mr. 

 Benham, who have seen the animal in its native state, report that
