scrub robin, Eirythropygia leucophrys limpopoensis (Santos Dias 

 195'i-D). Abdim's stork (Hoogstraall95^B, Sudan record above). 



Uganda hosts of specimens identified for the Museum of Com- 

 parative Zoology are: grey hornbill, Lophoceros n. nasutus ; 

 Grant's crested francolin, F. sephaena grantii ; yellow-beaked 

 francolin, F. icterorhynchus ; Abyssinian gonolak, Laniarius 

 erythrogaster, and several individuals of both kinds of guinea 

 fowl already noted from Equatoria Province, Sudan. 



Additional, recently obtained host data (Theiler, correspond- 

 ence) is as follows: Centre pus superciliosus from Uganda; "par- 

 tridges" from East London, eastern Cape, and southern Transvaal, 

 South Africa; Turdoides jardinei and Orthochagra Senegal from 

 l«Iaringua, Mozambique; and Falco'biramTcus from Fietermaritzburg, 

 Natal. 



The possibility that the record of a nymphal H. leachii 

 muhsami from a tchagra shrike in Mozambique (Santos Dias 1954C) 

 refers actually to H. hoodi hoodi shoiild be considered. 



The subject of psirasitism of birds by ticks has been reviewed 

 briefly by Schulze (1932B). 



BIOLOGY 



Aside from indications that H. hoodi hoodi feeds exclusively 

 on birds, chiefly on those that feed on the ground, and that all 

 of its stages occur on a single host, little else is known of 

 their biology. If domestic chickens were frequently attacked, 

 more reports probably would have appeared in the literature. In 

 Portugese Guinea, however, Tendeiro (1947) reports this parasite 

 to be common on domestic chickens and in Entebbe, Uganda (Lucas 

 1954-) , a flock of chickens was found so heavily infested that 

 a number of hosts died or were badly debilitated. 



The distribution of H. hoodi hoodi presumably is much more 

 continuous in tropical Africa than present meagre records indicate, 

 Phylogenetically, H. hoodi and related species, all of which close- 

 ly resemble it, represents an old, quite static lineage. In Africa,
