Ord. Kaptores. Fam. Aquilidse. 



3. Buteo Bairdii. Baird's buzzard. 



4. Buteo elegans. 

 Fam, Vulturidse. 



.5. Cathartes aura. The Turkey-buzzard. 

 Ord. Grallatores. Fam. Charadridse. 



6. Charadrius hiaticula. The piping plover. 

 Ord. Natatores. Fam. Laridse. 



7. Stercorarius pomarinus. 



8. Hydrochelidon fissipes. 



Fam. Anatidse : 9. Anser frontalis. 



Fam. Alcidge : 10. Uria grylle. 



11. UiiaTroile. 

 Of these eleven species, Xanthornis varius was known to us as 

 Canadian, but accidentally omitted. We hesitated about the two 

 species of Uria, but did not consider that we had certain evidence. 

 Both species of Buteo, and the Anser, we still regard as uncertain as 

 to their being good species. 



We add, here, that in our list, Ibis falcinellus should have been 

 I. guarauna, which is equivalent with I. Ordii, of Mr. Mcllwraith's 

 list. Phaleropidse should have been made a family, and Alcidse 

 occurs twice, being, in the first instance, a misprint for ("olymbidse 

 Divers. We shall be glad to record any further additions to the list 

 of our Native birds . 



Mr. Mcllwraith deserves the gratitude of all Canadian orni- 

 thologists. W. H. 



A short treatise on the Milk-weed, or Silk -weed, and the Canadian 

 nettle, viewed as industrial resources. By Alexander Kirkwood. 

 Read before the Ottawa Natural History Society, 15th. Feb., 1867. 

 This little pamphlet deserves the attention of all who are inte- 

 rested in the growth and prosperity of this Province ; and, especially, 

 of all who are engaged in agricultural pursuits. It is strictly a prac- 

 tical treatise, giving instructions for the culture of the plants, and 

 preparation of the fibre, as well as showing the reasons for believing 

 in their value as textile materials. The subject well deserves atten- 

 tion, and we hope Mr. Kirkwood' s treatise will obtain a large circu- 

 lation, and exercise a useful influence. W. H.
