Mention should be made here of an important paper by Jean Delacour and Dean Amadon (1949). The Relationships of Hypocolius (Ibis, 91:427-429, plates 19 and 20) which appeared after the present paper by Arvey was written. Delacour and Amadon stated that Hypocolius, a monotypic Persian genus, should be assigned to the Bombycillidae. Their conclusions (op. cit.:429) were as follows: "It might be advisable to set up three subfamilies in the Bombycillidae, one for Bombycilla, one for Hypocolius, and a third for the silky flycatchers, Ptilogonys, Phainopepla and Phainoptila. Further study may show that Dulus can be added as a fourth subfamily.

"Previously the Bombycillidae appeared to be an American group of which one genus (Bombycilla) had reached the Old World. Inclusion of Hypocolius in the family makes this theory uncertain. Without obvious affinities to other families, and consisting of a small number of scattered and rather divergent genera, the Bombycillidae would seem to be a declining group whose origin cannot safely be deduced from the distribution of the few existing species."
