row of granules. Meropodites of walking legs nearly 3 times as long 
as broad, in © apparently somewhat broader than in the ©. 23 
Lateral margins of external orbital angles subparallel, longer 
than those of the epibranchial teeth; anterior margin of front with a 
deep emargination. Inner surface of palm of cheliped with prominent

transverse crest, the edge of which is granulate. 
Ses. angustifrons A. Milne-Edwards. 
Lateral margins of external orbital angles much converging 
posteriorly, shorter than those of epibranchial teeth; anterior 
margin of front with a shallow emargination, not visible in front 
view; a transverse ridge on the surface of the front, on either side 
of the median emargination, about as broad as the inner postfrontal 
lobes, and near to the lower margin of the front. Inner surface of 
palm of cheliped with granular, transverse, not prominent row. 
Ses. amphinome de Man. 
Upper border of movable finger of cheliped very minutely trans- 
versely grooved. | 25 
Upper border of movable finger of cheliped mostly with a longi- 
tudinal row of spinules. 26 
Carapace punctate, with isolated small tufts of hair; lateral margin 
of external orbital angle longer than that of epibranchial tooth; 
distance between external orbital angles always less than length 
of carapace in the median line. Upper border of movable finger of 
cheliped granulate at base and with about 50 transverse grooves. 
Ses. weberi de Man. 
Carapace very strongly and closely granulate; lateral margin of 
external orbital angle shorter than that of epibranchial tooth; distance 
between external orbital angles equal to or slightly exceeding the 
length of the carapace in the median line. Upper border of movable 
finger of cheliped with numerous transverse grooves, at the inside of 
which a longitudinal row of 6—7 denticles is found. 
Ses. leprosa Schenkel. 
Upper border of movable finger of cheliped rather irregularly 
granulate, the granules occupying the proximal two-thirds of the finger, 
8—10 of which are dentiform; under margin of immobile finger den- 
tate; inner surface of palm with transverse row of granules. 
Ses. perraccae Nobili.
