In this genus tbe lobing of tbe lip bas been variously described, 

 dependent on tbe view taken of tbe small divisions at tbe base of the 

 lamina ; these I have described under T, qtiinquefida in the * Flora of 

 British India,' as the normal side lobes of the lip, and regarded the 

 broad blade as a 3-lobulate midlobe. I now think that the smaller 

 divisions should more properly be regarded as auricles or appendages 

 of the lip, and have hence so described them here in this and the pre- 

 ceding species. For an observation on the affinities of Thecostelej see 

 under the description of the preceding plate. — J. D. H.
