The typical specimen of this new species, was obtained by Mr. Audebert, on the tenth of June 1878, in the neighborhood of Ambodikilo near Mananare a place on the Southwestern shore of the bay of Antongil. Our traveller states that this was the only example of the species which he met with during a course of two years in the North-Eastern parts of Madagascar, a fact leading to the conclusion that this species is much less generally distributed in the country mentioned than its congener, the Cuculus himalayanus or Rochii. The next allied species of Cuculus Audeberti is the Indian Cuculus sparveroides, Vigors, from the continent of India, put by modern ornithologists, after the example of S. Müller in the subgenus Hierococcyx.
