er tone. The petals, very narrow
at base, are yellowish green, suffused and lined with copper above, paler
below. The slipper shows similar colouring.

On the same plant, open at the same time, but from another stem, was a
flower of the common Dauthierii type. Still more remarkable, one year this
second stem bore a flower of which half the dorsal was pale yellow, the
other half coppery green, as is usual, thus betraying a futile inclination
to rival its albino sister. The petals were scarcely affected, however.

_Dauthierii marmoratum._--Another abnormal form. The point of the dorsal,
and the high shoulders, are white, the rest crimson-maroon. From the point
descend three or four broad lines, or long splashes, of green, with
striking effect. The petals are marbled longitudinally with purple on a
dusky ground. The lip is dull, dusky crimson.

_Lord Derby_ (Rothschildianum x superbiens).--An immense flower--the grand
dorsal rosy white, tinged with pale green in the middle, pale purple on
either hand, dark lines circling upward over all. The petals, outlined
with purple at the base, change to pale green, almost to white, below and
at the tips. Great spots of darkest crimson stud the whole. Slipper
maroon, greenish at the toe.

_Evenor_ (Argus x bellatulum).--Ground-colour throughout ochreous yellow.
The dorsal has a purplish base and maroon lines of dots. Broad round
petals, closely spotted with maroon. Slipper purplish above, ochre below.

_Excelsior_ (Rothschildianum x Harrisianum).--Dorsal long,
high-shouldered, greenish, with darkest crimson edging lines of the same
tint, and white margin. Petals depressed, of a like green, crimson along
the upper edge, covered with the heavy spots and hairs of Rothschildianum.
Slipper very long, dull crimson.

_Engelhardtiae_ (insigne Maulei x Spicerianum).--The dorsal has very broad
shoulders, narrowing to a wasp-waist, where the upper white changes
abruptly to bright green, spotted with pink. A strong crimson line runs
from base to tip. Petals so evenly curved downwards that they seem to make
a half-circle, coppery yellow in hue, handsomely gauffered on the upper
edge, and lined with copper colour. Immensely wide lip, coppery ochre with
a bright green lining.

_Edwardii_ (superbiens x Fairieanum).--Dorsal long, white-edged, stained
at the margin with purplish crimson and lined with the same. Short narrow
petals, very strongly bowed, greenish, edged throughout with purplish
cr
