Mr. im Thurn notes that in Guiana E. ¿imatophyllum is always associated with ants, 
and it is a curious coincidence that, in securing this, the only specimen which we saw, 
Dr. Evans was severely stung by a swarm of small yellow ants. Ants frequently take up 
their quarters in decaying orchid pseudobulbs, which they apparently excavate for the 
purpose; but inasmuch as the present species belongs to a section without pseudobulbs, 
the insects probably inhabit the spaces between the stem and the closely-appressed leat- 
sheaths. Anyway,a few undoubted ant-holes are to be seen in the leaf-sheaths of my 
specimen, which, moreover, has a solid stem. {Amazonia, Guiana. |

Ad hoc genus forsan relegandum exstat insequens: 
EPIDENDRUM ($ AMPHIGLOTTIUM ?), sp.? £.caule folioso, stricto; fos distichis, lanceolatis 
obtusis vel obtusiusculis, 8:0-18:0 em. long., 1:7—3:3 cm. lat., coriaceis ; inflorescentise 
terminalis axe elongato, post fructificationem radices et caules foliosos novellos juxta 
apicem gignente. Neque flores nec fructus suppetebant.

These specimens were dried solely on account of their curious morphology. It occa- 
sionally happens in a few genera of Orchids that the axis of the spike will bud after 
flowering, instead of dying down; in the present case this seems to be the rule, and 
not exceptional.

The flowers are somewhat smaller and the leaves narrower than is the case with 
typical catenulata, but I agree with Mr. Rolfe in considering these insufficient grounds 
for making a new species. [Guiana, Peruvia. |
