Lyncornis cerviniceps, Gould, in Proc. of Zool. Soc. Part VI. 1838. I Ave never seen more than a single specimen of this truly beautiful Goat-sucker ; and this I received seven years ago ; it was said to be a native of China or the adjacent islands. I have selected it as the type of the genus Lyncornis, a minor group among the Caprimulgide, conspicuous for their large eyes, lengthened egrets, and great powers of flight. The analogy of this group to that of the horned owls is too palpable to escape observation ; the irides of the members of this genus will in all probability prove to be either yellow or hazel. The species described above is in the collection of the Zoological Society. The figure is of the natural Size.
