SUBORDINATE MARKINGS OF FEATHERS OF BIRDS. By WILLIAM E. GLEGG, F.Z.S., M.B.O.U. [Read February 23rd, 1946.] IN 1944 I conducted an enquiry (cf. The Ibis, 1944, pp. 511-16), the purpose of which was to determine how many species were affected by these markings, which may be described as bars, in what part of the plumage they appeared and whether sex, age, locality, season or colour have any bearing on the appearance of this feature. To control the extent of the enquiry it was decided to confine it to birds on the British List. The plan for the material was to examine an adult male and female and immature male and female of each species in so far as specimens were available. A total of 935 skins was examined, this number being composed of 385 adult male, 341 adult female, 94 immature male, 79 immature female, 18 adult unsexed and 18 immature unsexed. These figures include a series of twelve birds very much affected by albinism and a series of twenty Blackbirds. The countries from which the skins came are too numerous to mention, and for the sake of brevity it may be said that they came from all over the world. 2 Hurlbutt's description of this piece is "This is a very beautiful octagonal Bow porcelain plate, 81/2in. across, decorated with applied prunus sprays on the border, interspaced with flowers ; the Cavetto, or hollow centre, being painted, with a Chinese rock and flowers, in fine raised enamels, in the famille rose manner. This is a very striking plate and has a milky body and fine clear unctuous glaze. It would appear to be of early make, probably about 1750-55. No mark." 3 Hurlbutt states that all European pieces of white glazed prunus sprigged ware were copied, either directly or indirectly, from the earlier Fuchien ware of China.
