HORN EXPEDITION—MAMMALIA. 
(o) Monoiremata .—As might liave been expected, the family Ornithor- 
hynchidaj is not represented in the Eremian region at tlie present time. Tlie only 
permanent waters are rocky holes amongst the ranges, and these are unCt for 
habitation by Ornithorhynchus. The family Echidnidie, on the other hand, has a 
wide distribution amongst the rocky hills, being certainly found at Barrow Creek 
in the north and Charlotte Waters in the south. Those from the former district 
are stated to be remarkably small; but those from the latter, though very much 
smaller than the largest specimens known from Queensland, are still of medium 
size. 
The following is a list of the mammals secured, the various species of which 
are dealt with separately :—
