Chiloschista Godeffroyana Schlechter Orch. Sino-Jap. 
Prodr. (1919) 275. 
This species seems to belong to the genus Chronio- 
chilus rather than to any of those genera to which it has 
been previously referred. The structure of the lip would 
exclude it from both Thriaspermum and Sarcochilus; 
from Chiloschista it is distinguished easily by means of 
the vegetative structure.

SACCOLABIUM Blume 
There have been eight species of Saccolabium described 
from Polynesia, Micronesia and Melanesia. Six of these 
species are apparently very closely allied, if one may de- 
pend upon published descriptions, in fact so closely allied 
that specimens at hand cannot be determined from the 
written descriptions. These species are Saccolabium Ber- 
tholdii Reichb.t., S. constrictum Reichb.f., S. Graeffei 
Reichb.f., S. Aaqjewshii Ames, S.minus Reichb.f. and JS. 
Vaupeli Schitr. The seventh species, 8S. guamensis Ames, 
is amply distinct; the eighth species, S./utewm Volkens, is 
not well described yet does not seem to be referable to
