MALLOPHAGA FROM AFRICAN HOSTS. 149 
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 (#1. H. King). 
Liperus gambensis, Piaget. 
A number of specimens, male and female, of this striking form from the 
spurwing goose (Plectropterus gambensis), 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, Rudow. 
A number of specimens, both sexes, from a white-necked raven (Corvultur 
albicollis), 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. 
Several specimens from a chicken, Meko, Southern Nigeria (J. J. Simpson). 
Menopon spinosum, Piaget. 
A male and a female from a_ starling, Malachal, Egyptian Sudan 
(H. H, King). 
Menopon africanum, sp. n. (Pl. V, fig. 3). 
Three adult female specimens and one immature, from the spurwing goose 
(Pleetropterus gambensis), Khor Felos, Egyptian Sudan (#7. H. King). This 
species is unlike any of the few Menopons so far found on geese or raptorial 
birds.
