168 BIRDS OF THE 



Surniculus luguhris Salvad. Ucc. Born. p. 63; Everett, L. B. Born, 

 p. 172; Sharpe, Ibis 1890, p. 10. 



Three adult specimens from Mount Kenepai, Nanga 

 Raoen and Liang Koeboeng and eight adult specimens 

 from the Upper Mahakkam. — Iris dark brown, bill black, 

 feet purplish, soles ochre-yellow. 



Hab. From India and Ceylon to South China, Southern 

 Philippines, Borneo, Sumatra and Java (Shelley, Cat. B. 

 Br. Mus. XIX, p. 227, mentions Batchian as habitat of this 

 species, but this is undoubtedly an error, this species being 

 represented on that island by S. Musschenbroeki Meyer).

 Cuculus Sonneratl Everett, L. B. Born. p. 170; Shelley, Cat. B. Br. 



Mus. XIX, p. 262. 



An adult male (N" 1002) from Mount Liang Koeboeng. — 

 Iris brown, bill black, lower mandible horny gray, feet 

 yellowish green. 



Hab. South-eastern Asia, Malay Peninsula and Sunda 

 Islands. 



This species is mentioned, as quoted above, under the 

 name of Cuculus Sonnerati by Everett aud Shelley. I feel, 

 however, obliged to maintain the generic name Penthoceryx 

 for the two species Sonnerati and pravatus, convinced as 

 I am that these two species cannot be placed in the genus 

 Cuculus proper. This latter is always characterized by more 

 or less pronounced longitudinal shaft-spots on at least 

 some of the tail-feathers, which character is quite peculiar 

 to this genus only, and as it is not found in Cacomantis 

 Sonnerati and C. pravatus, which two species are, moreover, 

 much smaller than the average size of Cuculus, I do not 

 hesitate to place them under the generic name Penthoceryx 

 as proposed by Cabanis and Heine and later on maintained 

 by Salvadori and other ornithologists.
