(Fig. 1.)

Mr. Ford.

Draw the smaller & more elongated of the 2 peacock's feathers; but the naked barbs round the disk at further end to be drawn as in the larger feather.

Attend to very narrow dark edging outside the broad coppery brown disk & the successive shaded zones towards the circumference.

Attend to trace of notch or inequality in the coloured zones at base of the eye or disk.

[In Descent 2: 137, fig. 53: "Feather of Peacock, about two-thirds of natural size, carefully drawn by Mr. Ford. The transparent zone is represented by the outermost white zone, confined to the upper end of the disc."]

(Fig. 2.) One of the tail-covert of Polyplectron Chinquis to shew the double eye. Attend to zones

[In Descent 2: 90, fig. 51.]

(Fig. 3.) One of the tail-covert of P. Hardwickii to shew the two eyes partially confluent. (The specimens are loose skins in box)

Shew the metallic green or blue-black central part of eye or disk by the same kind of shading in the peacock & Polyplectron.

[In Descent 2: 138, fig. 54: "Part of a tail-covert of Polyplectron chinquis, with the two ocelli of nat. size."]

N.B. Then 3 figs to go on same block- The Peacock's feather will have, I suppose, to be reduced.
