Summary
Haemoproteus majoris, originally described by Laveran from Parus major in France but hitherto denied specific status, is redescribed from P. major in Great Britain and designated a valid species. H machlolophi de Mello (1935) of P. xanthogenys in India is considered to be a synonym of H. majoris. The occurrence and distribution of haemoproteids in other Paridae is briefly discussed.
