M. deltoideus ; labello imberbi sagittate triangulari, angulis posticls rotundatis 

 dentatis apice dllatato calloso margine recuryo basi tuberculato. 



Planta omnino facie M. cernui ; foliis quodammodo latioribus. Rachis 

 purpurascens, angulata. Bracte^ parvce, memhranacece, acuminulatcB. 

 Petala et Sepala subcequalia, lineari-lanceolafa, virescentia, purpureo-macu- 

 lata et interrupte fasciata. Labellum sepalis duplo breviiis, versus basin 

 saccatum, planum, caryiosum, atro-purpureum, disco virescente, tuberculo 

 unico oblongo pone basin, et callo virescente ad apicem. Ccetera M. cernui. 



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.
