The longitudinal crest at the upper border of the palm is often broken 
up, not entire; the upper border itself is much rounded off, and at the 
inner side of it numerous granules, similar to those composing the lon- 
gitudinal crest, are placed in subparallel, short rows; the inner surface 
of the palm is provided with larger granules and near the base of the 
fingers an elevated knob bears some crowded granules, but only in adult 
specimens a true transverse row may be found (I have examined a rather 
large number of specimens, collected at Nias, and belonging to the Am- 
sterdam Zoological Museum). There is a large tubercle and several 
smaller ones at the inner side of the base of the immobile finger. The 
characteristic prominent tubercle at the outer surface of the palm, is, as 
de Man (1902) remarks, nearly or wholly absent in the Q, but also 
young © have only a trace of it. As it is on account of the absence 
of this tubercle that Ortmann founded his species Ses. jacquinoti and 
de Man described a specimen (1902, p. 508—509), which appears in this 
respect to be identical with Ortmann’s species, but was regarded by de 
Man at most as a variety, I see no reason to maintain Ortmann’s 
species as distinct.
