lip is different, In place of the thin knife-like crest of 
that species, there is a broad raised oblong fleshy table 
of a yellowish brown colour, closely wrinkled across and 
broken up into asperities, which, at the front of the table 
where it forms a kind of cliff above the lip, are extended 
into strong teeth. On the outside of the lip near the 
point the veins are raised and somewhat toothed. ‘The 
colour and size of the flowers are much the same as in 
C. laminatum. : 
C. saccatum (Lindley in Botanical Register, 1840. misc. 
179. Sertum Orch. t. 41.); sepalis lanceolatis paten-

abrupté acuminato fimbriato medio saccato: ostio con- 
tracto reniformi posticé dentato, columna cirrhatá.—— 
Demerara.——This has very large flowers, with rich 
purple-spotted sepals and petals, and a bright yellow lip 
covered closely with crimson dots. The latter is pierced 
in the middle by a narrow aperture, that leads into a 
conical chamber or bag, which is not observed till the 
back of the lip is turned up.

—— This is a singular plant whose flowers before opening 
might be mistaken for C. tridentatum, but when ex- 
panded they are totally different. The sepals and petals, 
which are very pale dull green outside, are slightly pink 
inside, and richly spotted, in irregular bars, with a deep 
crimson-purple. The lip is a most singular organ, and 
very difficult to describe. Viewed from the side it has 
a hemispherical form, and is green except at the base, 
where it is extended into a black-purple lacerated mar- 
gin embracing the column, and at the point where it is 
extended into a long flat horn or nose. Seen in front it 
is almost wholly of the same rich black-purple, and looks 
as if it were a solid hemisphere pierced in the middle with 
a large heart-shaped hole; but this appearance is owing 
to a thick fleshy rim which rises from within the true
