1905. ] OF THE FAMILY GALAXIIDA. 365 
The author has also been permitted to examine the types of 
G. scriba and G. ornatus, preserved in the Paris Museum, and 
those of G. attenuatus, G. maculatus, and G. alpinus, 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 Neochanna.
