THE BIEDS OF AUSTRALIA. 
Mr. Eagle Clarke of the Scottish National Museum, has also always 
been ready to allow comparison with the specimens collected by the Scottish 
National Antarctic Expedition, and thereby interesting notes have been 
obtained for which thanks are tendered. 
Dr. Peringuey, Director of the South African Museum, courteously for- 
warded me the collection of Prions from that Institution, and I was thus 
enabled to fix the South African forms by comparison with the types of 
Smith’s species preserved in the British Museum. 
Mr. A. F. Basset Hull, whose investigations into this hitherto neglected 
group have already borne such good results, forwarded some very interesting 
specimens, including the type of (Estrelata montana Hull, the property of the 
Australian Museum, Sydney. To both Mr. Hull and the Trustees of the 
Museum must the thanks of all Australian ornithologists be rendered, as 
through this action the solution of the mystery surrounding Gould’s 
Procellaria solandri was brought about. 
I hope I have made it obvious that a very wide field for investigation 
awaits Australians in this branch, and that co-operation with Mr. Hull would 
bring about more valuable results : I have indicated some of the points that 
have attracted me in the course of the work. 
In conclusion, I would again ask all my friends for a continuation of their 
help, and would also ask all those who have observed the lack of life- 
histories to aid in filling up the blanks.
