(Muscicapidae; † Swynnerton's Robin S. swynnertoni) Charles Francis Massey Swynnerton (1877-1938) English settler and farm manager in Southern Rhodesia / Zimbabwe 1897-1919; "The Melsetter Robin, described by Shelley (Bull. Brit. Orn. Cl. XVI. 125, 1906) under the name of Erythracus (= Erithacus) swynnertoni, differs in several important respects from all the northern species commonly associated in the genus, some of which have already received generic names, and it may therefore be placed in a new subgenus bearing the name of SWYNNERTONIA, in honour of Mr C. F. M. Swynnerton, who is not only responsible for the discovery of the species but has also contributed very largely to our knowledge of our tropical species of birds.  The wing formula of the genus is: second primary much shorter than the secondaries and the tenth primary, the third a little shorter than the seventh and the fourth, fifth and sixth primaries subequal; the bill is black and the legs and feet are pinkish; three conspicuous bristles are present in the specimen examined and the tail is relatively short as compared with other species." (A. Roberts 1922); "Swynnertonia A. Roberts, 1922, Annals Transvaal Mus., VIII (4), p. 232.  Type, by monotypy, Erythracus swynnertoni Shelley, 1906." (JAJ 2020).
