long and 8 mm. broad. Lip 3-lobed, triangular in out- 
line, about 2 mm. long and as broad, joined to the col- 
umn-foot by a longitudinal keel; lateral lobes erect, ob- 
tuse, about 2 mm. long, thickened on the inner surface ; 
mid-lobe much thickened, with a median ridge, strongly 
recurved; disc more or less pubescent. Column charac- 
teristic of the genus; column-foot floccose near the June- 
tion with the column, about 2-8 mm. long. 
Ceratostyhs Lohert has no near allies known to the 
author. It may be distinguished easily by the 8-lobed lip 
and by the method of attachment of the column-foot to 
the lip. This latter character is also found in Schlechter’s 
genus, E:\piblastus.
