ZOOLOGISCHE MEDEDEELINGEN — DEEL HI. 
Carapace with numerous transverse striae, oblique on the branchial 
regions. Sides strongly convergent posteriorly, without a tooth behind 
the external orbital angle. Upper border of palm of cheliped with a 
longitudinal line, with a number of oblique lines on the inner, and 
some fainter ones on the outer sides; all these lines not pectinated, 
but beaded; upper border of mobile finger with some fine, oblique, 
beaded lines near the base. Meropodites of walking legs with 2—3 
strong teeth at the posterior margin; meropodites of hinder legs 
moreover with 2 teeth, placed side by side, near the proximal end. 
Ses. murrayi Calman. 
Sides of carapace parallel. Transverse tubercles on upper border 
of mobile finger of cheliped smooth. 
Sides of carapace convergent distally. 8 
Upper border of mobile finger of cheliped with a row of 16 trans- 
verse tubercles, symmetrical with respect to the longer axis of the 
latter; inner surface of palm with a transverse row of granules. Width 
of front between the eyes only very slightly longer than half the 
distance between external orbital angles. Middle-sized species, distance 
between external orbital angles 20 mm. Ses. picta de Haan. 
_ Upper border of mobile finger of cheliped with only 5—6 obscure, 
low tubercles, that (according to the figure of Lanchester) are not 
symmetrical with respect to the longer axis of the tubercles, as the 
proximal slope. is longer than the distal one; inner surface of palm 
without transverse row of granules, smooth. Width of front between 
the eyes distinctly more than half the distance between external orbital 
angles. Small species, distance between external orbital angles about 
9 mm. Ses. fasciata Lanchester. 
Transverse tubercles on upper border of movable finger of cheliped 
symmetrical with respect to their longer axis, numbering 11—14, each 
of which has a narrow smooth stripe in its longer axis („Chiton”-like). 
Meropodites of walking legs very broad, not exactly twice as long as 
broad. Ses. plicata (Latreille). 
Transverse tubercles on upper border of movable finger of cheliped 
not symmetrical with respect to their longer axis, so that the proximal 
slope is longer or shorter than the distal one. ~9 
- Proximal slope of the said transverse tubercles longer than 
distal one. 10
