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.

Dcmerara. — - — 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
