considerable exertion, such as the digging up of bulbous and tuberous 

 roots. The tarsi and feet are strong, the toes of considerable length, with 

 the claws long, and formed for scraping. The colours of the plumage are 

 generally different shades of brown, red, orange, grey, and white; the 

 marking in bars, waved lines or spots, as in the true partridges. The head 

 is always crested. 



We have placed the two new species described in the present number 

 as the types of the genus ; the one as possessing all the characters de- 

 veloped in the greatest degree, the other as exhibiting the form with the 

 lengthened tail, but characteristic in other respects. Ortyoo Sonnini {Per- 

 dioc Sonnini, Temminck), is also true to the type : the bill is slightly mo- 

 dified ; but Or. borealis recedes considerably, and connects this form with 

 the true partridges and quails. 



We have marked Or. dentata with a doubt as belonging to this genus, 

 having never seen the bird, and cannot assert it on our own authority. 

 Or. Falklandica and Californica appear both dubious species, particularly 

 the latter.
