* The Director of the Dominion Museum, Wellington, kindly informs me that the type of this 

 species is not now in the Museum. He adds that it is believed to have been " thrown out about 

 thirty years ago when extensive rearrangements were made in the Museum, following a change in 

 the Directorship '*.
