Descriptions of New Species of Birds. 51 



Length, 3J in. ; wing, l-£ , tail, 1-J- ; bill from termination of frontal , 

 feathers, A. 



A younger specimen, but with the crest fully developed, has the throat 

 whitish-ash, and the outer two lateral feathers tipped with the same. 



The female, as in the allied species, is without the brilliant crest. 



Habitat : Venezuela. Type in my collection. 



Remarks. This is a close ally of 0. cristatus from Barba- 

 does ; the two colors of the crest are equally divided in both, 

 but they differ in shades of coloring ; the green in the new 

 species is without the strong golden tinge existing in the other, 

 and the violet is rather deeper in color, which color it retains 

 in all positions — whereas in some lights that of 0. cristatus is 

 greenish ; the upper plumage of the latter is lighter and of a 

 golden-green ; the new species is also rather smaller, with a 

 longer bill. They differ strikingly in the euds of the tail-feath- 

 ers, these being obtusely pointed in the new species, and 

 rounded in the other. 



0. ornatus I have not seen, but judging from the descrip- 

 tion and plate of that species, a comparison with it is not nec- 

 essary. 



3 — Oyrtonyx Sumichrasti. 



In February of this year, Prof. Sumichrast sent me the de- 

 scription of a supposed new species of Oyrtonyx, obtained by 

 him in the mountains of Santa Efigenia, with the request that 

 I would investigate its claim to novelty. He promised to for- 

 ward the specimen by the first opportunity ; but so long a time 

 having elapsed without its coming to hand, and being satisfied 

 that it is a new species, I have concluded to give a translation 

 of his description, which from his known capability may be 

 relied on as correct. 



" Male. Head of a deep black, streaked with white, the feathers of the 

 occiput forming a sort of loose tuft of pale ashy-brown ; feathers of the 

 back light leaden-gray, marked in the centre with a pale cinnamon-red 

 stripe extending the entire length of the shaft, and with transverse black 

 spots on each side ; wing coverts pale ashy-gray, with a cinnamon-red 

 stripe running the length of the shaft, and with black spots on each side ; 

 remiges brownish-black, spotted outwardly with white (on the primaries), 

 and with reddish- white (on the secondaries) ; breast of a light red, the
