Piaget. This is owing to the fact that he considered his specimens as immature 

 and that they had not as yet developed abdominal blotches. Our specimens, 

 however, which are without question mature, show this to be a distinct species. 



Liperus baculus, Nitzsch. 



Two specimens from a blue pigeon, Malachal, Egyptian Sudan {H. H. King). 



Liperus gambensis, Piaget. 



A niimber of specimens, male and female, of this striking form from the 

 spurwing goose {Plectropterus gamhensis), Khor Felos. Egyptian Sudan 

 {H. H. King). 



Colpocephalum flavescens, Nitzsch. 



Several specimens of this well marked species from a vulture, Oshogbo, 

 Southern Nigeria {J. J. Simpson). 



Colpocephalum semicinctum, Endow. 



A number of specimens, both sexes, from a white-necked raven {Corvidtur 

 alhicollis), Oshogbo, Southern Nigeria (J. J. Simpson). 



Colpocephalum sjoestedti, Kellogg. 



One female from a spotted rat, Kyetume, by Kampala, Uganda {Dr. R. van 

 Someren). This host of course is not normal and shows straggling. Also 

 another Colpocephalum, species not determined, was recorded from the spotted 

 rat. This is also, probably, a straggler. 



Menopon mesoleucum, Nitzsch (?). 



One specimen from an owl and one from a starling, Malachal, Egyptian Sudan 

 {H. H. King). 



Menopon pallidum, Nitzsch.

 (//. H. King). 



Menopon africanum, sp. n. (Pi. V, fig. 3). 



Three adult female specimens and one immature, from the spurwing goose 

 {Plectropterus gamhensis), Khor Felos, Egyptian Sudan {H. H. King). This 

 species is unlike any of the few Menopons so far found on geese or raptorial 

 birds.
