This makes the fourth species..of the present curious 
genus, and in all probability many more will be added. 
It is a native of trees in the neighbourhood of the great 
waterfall of the Demerara river, where it was found by Mr. 
Joseph Hubbard, who sent it to his friend Mr. Booker of 
Liverpool, by whom it was presented to Richard Harrison, 
Esq. of Aighburgh. ..To the latter gentleman I am indebted 
for the fine specimen from which the accompanying drawing 
was made in October, 1835. 
Its distinction from the other species resides in its lip, 
which has none of the fringe-like hairs of M. barbatus and 
cristatus, but is flat, of a thick fleshy consistence, and of a 
rich purple colour with a dash of green on its centre; its 
figure is arrow-headed, with the barbs rounded off and ser- 
rated, and the point a little dilated with the edges reflexed.
