One specimen only of this species was contained in the collection 

 formed by the present Expedition. It was found at Monterey. Long 

 before the specimen appeared in this country, the species had been accu- 

 rately described to me by Mr. Douglas, together with a second new 

 apecies nearly allied to it, as well as to Ortyx Calif arnica ; a beautiful group 

 being thus formed by these three Western Tetraonidce, closely united in 

 character, by the elevated crest and the general similarity of colour and 

 markings. The descriptions of these two new species of Ortyx, together 

 with an account of five new species of Grouse from the same quarter, 

 have been given by Mr. Douglas to the Linnean Society, and will 

 speedily be published in the Transactions of that body. As I had 

 received the bird now before me for description from Captain Beechey, 

 Mr. Douglas kindly conceded to me the right of naming it, which in 

 course should have devolved upon himself. I seize with pleasure the 

 opportunity thus afforded me of giving it the name of the first discoverer. 

 And in performing this customary act of justice, I offer some slight 

 discharge of the obligations I owe for much valuable information respect- 

 ing the Zoology of North Western America. Few individuals perhaps 

 have done more to elucidate the Natural History of any distant country, 

 than Mr. Douglas has effected in regard to that very interesting part of the 

 World. I believe myself correct when I state that more than six hun- 

 dred new species of plants have been discovered and brought home by 

 him, and, from the congeniality of our climate to the vegetable produc-
