1905.] OF THE FAMILY GALAXIID^. 365 



The author has also been permitted to examine the types of 

 G. scriha and G. ornatus, preserved in the Paris Museum, and 

 those of G. attemoatus, G. macidatus, and G. alpimcs, in the 

 Museum of the University of Cambridge, 



The author wishes to gratefully express his thanks to the 

 Director of the Australian Museum, to Mr. E. R. Waite, to 

 Professor L. Vaillant and to Dr. S. F. Harmer. Also to Mr. J. 

 A. Wolffsohn, who has kindly sent him a copy of Philippi's paper 

 describing the Chilian species. 



27 species may be regarded as well established, but this number 

 will doubtless soon be augmented. Two genera may be recognised, 

 Galaxias and Neoclimina.
