bristles (fig. 1. a.), the lateral cirrhi are not formed, the 
curved horn is wanting, and the helmet-like form in the lip 
is completed. All these transitions were perfectly shewn in 
the Duke of Devonshire's specimen, and have been faith- 
fully copied by Miss Drake. On the same specimen was 
also a case of a flower with two lips, as is represented at 
figure 2. 
The necessary consequence of this is, that the supposed 
genera Myanthus and Monachanthus must be restored to 
Catasetum, and I have no doubt now, although no proof 
has been seen of it, that Mormodes must share the same fate. 
But which of the species have their masks on, and which. 
shew their real faces, I certainly will not at present presume 
. to guess. 
Mr. Schomburgh has lately sent to the Linnean Society, 
from Demerara, a specimen of another Monachanthus, 
sporting to a crested Myanthus ; of which, I presume, some 
account will in due time be published. And I am ac- 
quainted with the following example of this tendency in a 
very different genus. 
In August 1836, Mr. Willmer, of Oldfield, near Bir- — 
mingham, sent me a specimen of a Cycnoches, which had 
broad petals, a short column, hooded and dilated at the 
apex, and a broad roundish lip, gibbous at the base, and 
with its stalk much shorter than the column. It was, how- 
ever, destitute of scent, while Cycnoches Loddigesii has, as 
is well known, a delicious odour of Vanilla. I had no 
doubt of its being distinet species, and called it C. cucullata. 
But in the autumn of 1836, in the garden of the Horticul- 
tural Society, a plant of Cyenoches produced from the 
opposite sides of the same stem two racemes; those of 
one raceme were the well-known Ap Loja flowers of Cycno- 
ches Loddigesii, and of the other t e scentless flowers of 
the new C. cucullata.
