168 MR. P. L. SCLATER ON THE GENUS Coccyzus. [ Mar. 24, 
section of the genus, to which it clearly belongs if this mode of 
division be adopted ; but as regards the indistinct colour of the rec- 
trices it approaches more nearly to C. erythrophthalmus. 
4, CoccyzUs ERYTHROPHTHALMUS. 
Cuculus erythrophthalmus, Wils. Am. Orn. iv. p. 16, pl. 28. fig. 2. 
Coccyzus erythrophthalmus, Bp. Consp. p. 111; Sclater, P. Z. 8S. 
1859, p. 252; 1864, p. 122, et Cat. Am. B. p. 323; Léotaud, Ois. 
de Trin. p. 352 ; Sel. et Salv. Ibis, 1860, p. 276; Lawrence, Ann. 
L. N. Y. vii. p. 477; Gundlach, Rep. F. N. i. p. 295. 
Coceygus erythrophthalmus, Baird, B. N. Am. p. 77; Cab. et 
Hein. Mus. Hein. iv. p. 76. 
Supra fuscus, eneo sake subtus albus: rectricibus pallide 
cinereis, albido terminatis: rostro nigro: long. tota 11, ale 
5°5, caude rectr. med. 6, lat. 3°5. 
Hab. Eastern United States to Missouri plains (Baird) ; Cuba, 
rarely (Gundlach) ; Mexico (Sallé); Panama (M‘Cleannan) ; Bo- 
gota (Mus. P. L. 8.) ; Trinidad (Léotaud); Ucayali (Hauawell). 
This Cuckoo goes very far south, probably, however, only on its 
winter migration. It does not appear to visit the Antilles, except 
Cuba, and that rarely. 
5. CoccyzUS MELANOCORYPHUS. 
Coucou, Azara, Apunt. il. p. 365. no. 267.

Coccygus melanocoryphus, Cab. et Hein. Mus. Hein. iv. p. 77. 
Piaya melacorypha, Léotaud, Ois. de Trin. p. 349. 
Supra fuscus, pileo cinereo; regione auriculari nigra: subtus 
pallide ochraceus: rectricibus nigris albo terminatis, mediis 
duabus dorso concoloribus: rostro nigro: long. tota 11, ale 
4:6, caude rectr. med. 5°8, lat. 3°5. 
Hab. Buenos Ayres, Conchitas (Hudson); Parana and Tucuman 
(Burm.); Paraguay (Azara); S8.E. Brazil (Maz.); Rio et S. Paulo 
(Natt.) ; Borba (Natt.); Ucayali (Bartlett); Pebas (Hauaxwell) ; 
Cayenne (Mus. P. L. 8.) ; Trinidad (Léotaud); Lima, W. Peru 
(Nation). 
This Coccyzus has also an extensive range in South America, as 
will be seen from my list of localities. I have compared skins from 
Lima, Cayenne, Pebas, S.E. Brazil, and Buenos Ayres. The tinge 
of ochraceous colour below varies, as also the cinereous colour of the 
head ; but the species may be always distinguished from C. minor 
(with which it has been confounded) by its black beak.
