P. r. regulus Sundevall. 2. P. r. adustoides Clancey. • marks the type localities of the two races. There would appear to be no justification for the suggestion that the differences claimed for adustoides are the outcome of comparing recent specimens with those affected by post-mortem cabinet colour change, because material of regulus in the Durban Museum taken by Percival in the eastern Transvaal in the 1890's is only slightly redder and less olive dorsally than the recent material of this race from Southern Rhodesia before me. Viewed in series adustoides is decidedly darker on the upper- parts than regulus. Using the colour nomenclature of Villalobos, "Colour Atlas", 1947, the mantles of four adults (including the Type) of adustoides give the following readings: SO-6-1 °; SO-5-1 °; SO-5-1 °; SO-4-1 °, while two adults and two first year birds of regulus read as follows: OOS-7-2°; OOS-6-20; OOS-6-2°; OOS-6-2°. On the ventrar surfaces adustoides differs from the nominate race in having the throat dusky and concolorous with the breast and flanks and not dull white as in regulus. In this connection it should be noted that specimens of. Please note that these imag
