List of the Mammats indigenous to Tasmania. 17 
nicating the results of their own observations upon the same 
subject. 
I may remark, that the disturbance and muddiness of the 
water caused by the late operations at the entrance of the 
basin appears to have destroyed all the worms in the timber, 
which corroborates a fact which I observed at the harbour 
at Halifax, in Nova Scotia, when, though the worms were so 
destructive to the dockyard wharf as to make it necessary to 
cover them with copper,—yet the masts and spars lying on the 
mud, though not covered by it, were altogether untouched. 
It would be desirable to ascertain to what extent the 
action of muddy water is injurious to these worms, as we 
might perhaps gather some hints as to the means of pro- 
tecting the timber from their action. 
IX. A List of the Mammals indigenous to Tasmania. 
By Ronatp C. Gunn, Hsq., F.L.S. 
THE following list of the indigenous Mammals of Tasmania 
is as complete as the very limited means of reference at my 
command admits. I believe, however, it will be found to be 
nearly correct. Where deemed necessary I have added a few 
remarks, but will enter more fully into their habits in a sub- 
sequent paper.

The only two genera of Bats found in the island may be 
thus shortly distinguished :— 
Nyctophilus, Leacu, Trmminck. Ears united ; nostrils 
in the front part of a short lunate groove.
