Type in the Paris Museum. 



The three skulls (q to s) received from Dirk Hartog's Island, 

 Sharks Bay, the very locality where the original type of B. lesueuri 

 was obtained, have all decidedly smaller bullae than the Other speci- 

 mens collected further south. As this difference, however, does 

 not appear to be accompanied by any others, there is not sufficient 

 reason for the specific or varietal separation of the two forms.
