70. W. Pogonius vieilloti, Leach. (P. senegalensis, Licht.; P. 

 rubescens, Temm.) N.B. This generic name was originally written 

 Pogonia by Leach (Zool. Misc. vol. ii. p. 45), in which form it had 

 been preoccupied by a genus of plants. Illiger's name, Pogonias, had 

 also been preoccupied by a fish-genus ; but Leach afterwards cor- 

 rected it to Pogonius, which form had never been used before, and I 

 therefore retain it instead of Mr. G. R. Gray's name Lcemodon (erro- 

 neously written Laimodon). 



71. Trachyphonus margaritatus, Rupp. (Tamatia erythropyga, 

 Ehrenb.) 



72. Yunx torquilla, Linn. Identical with specimens from Britain 

 and from India. 



73. N. Oxylophus serratus (Sparrm.). This Cape bird has never 

 before, I believe, been obtained to the north of the equator. The 

 nearly allied O. jacobinus (Bodd.) of India (Cuculus melanoleucus, 

 Gm. ; C. passerinus, Vahl) has the lower parts constantly white. 

 Ehrenberg, in his * Symbolae Physicse,' fol. r, describes a Nubian spe- 

 cies under the name of Cuculus pica, which from the description 

 seems to be identical with the white-bellied 0. jacobinus of India. 

 Riippell erroneously refers this C. pica of Ehrenberg to the Oxylo- 

 phus afer, Leach (Levaill.Ois. Afr. pi. 209), of S. Africa, which differs 

 in having dark streaks on the throat, and which appears from Rup- 

 pell's observations to be also an Abyssinian bird. 



74. W. Oxylophus ylandarius (Linn.). 



75. W. Columba guinea, Linn. (C. trigonigera, Wagl.) 



76. Xumida ptilorhyncha, Licht. 



77 . Francolinus clappertoni, Vig. Mr. G. R. Gray has separated 

 the F. clappertoni of Riippell as a distinct species, under the name of 

 F. riippelli ; but the specimens from Kordofan seem to agree equally 

 well with Riippell's plate of F. riippelli and with Gray's plate of what 

 he regards as the true clappertoni, between which I can see no dif- 

 ference. 



78. Coturnix daetylieonans. 



79. N. W. Pterocles quadricinctus, Temm. (P. tricinctus, Sw.) 

 This African species has long been confounded with the closely allied 

 P. fasciatus (Scop.), (Perdix indica, Lath.), of India, figured by 

 Mr. Jerdon in his 'Illustrations of Indian Ornithology,' pi. 10 and 36. 

 Specimens sent by Mr. Jerdon have bow enabled me to prove their 

 distinction. The general arrangement of colour is almost identical 

 in these two species, the chief distinction being in the feathers of the 

 back, scapulars, tertials and greater wing-covers, which in P. fascia- 

 tus are marked transversely with bars of a dull iron-grey (or "inkv 

 hue," as Mr. Jerdon well describes it), while in P. tricinctus these 

 bands are of a deep glossy black. In P. fasciatus the wing-covers 

 next the body have two or three of these dark bands alternating with 

 white ones of equal breadth, the subterminal one being dark, and the 

 tip of the feather ochreous yellow. In P. quadricinctus the wing- 

 covers have only one black band, (or a very faint trace of a second,) 

 narrowly margined on both sides with a fine white line, the terminal 

 and basal parts of the feather being ochreous. Temminck's original
