176 BIRDS OF TASMANIA. 



Observations. — A certain amount of doubt exists as to whether 

 the Soft-plumaged Petrel is really found in Tasmanian waters. So 

 far as I am aware there are no records of this species having been 

 observed round our coasts, but, taking into consideration the fact 

 that Petrels in general are great ocean wanderers, there is no 

 reason to doubt that, occasionally at least, it comes to within close 

 proximity of the Tasmanian coast. 



Those who have observed this bird in its haunts state that it is 

 a very rapid flier and generally moves at a considerble height 

 above the surface of the water.

 the type specimen of which was secured by Gould in Bass Strait

Dr. F. Du Cane Godman is inclined to think that this Petrel 

 is but the dark phase of some other species, possibly (E. lessoni.
