granules at the inner surface of the palm; this somewhat con- 
cave row consists of about 10 granules, that form the distal boundary 
of the granulated portion of the inner surface of the palm. In de Man’s 
specimens, that were of smaller size, this row is not yet developed, and 
indeed I have observed it only in the two largest {. The horny 
margin at the tip of the fingers is much shorter than in de Man’s spe- 
cimens, occupying only one-fifth of the length of the finger, not one-third. 
This last feature and the slightly oblique direction of the proximal tuber- 
cles at the upper border of the mobile finger approach the specimens of 
the Natoena Islands somewhat to the typical Ses. ocypoda, which occurs 
in Benkoelen (Sumatra); de Man’s specimens of the subspecies have been 
caught in tbe Baram River (Borneo).
