of abdomen of © very broad, somewhat less than three times the 
length of this segment. Eggs of © few in number and large (subg. 
Geosesarma de Man). Ses. sylvicola de Man. 
Upper border of movable finger of cheliped with a longitudinal 
row of 9—10 acute denticles. Posterior margin of penultimate segment 
of abdomen of © short, less than twice the length of this segment. 
Eggs of © small and numerous. Ses. maculata de Man. 
Outer surface of palm of cheliped concave or at least much 
flattened in dorsal view, so that a sharpened edge is formed near the 
carpal joint; palm very high, closely granulate. Carapace convex ; with 
rather prominent, sharp postfrontal lobes; sides subparallel. 
Ses. bocourti A. Milne-Edwards. 
Outer surface of palm of cheliped regularly convex in dorsal view. 33 
Carapace strongly vaulted in longitudinal direction, with bunches 
of black hairs on the anterior part; epibranchial teeth nearly always 
reaching much farther outward than external orbital angles (especially 
so in the case of Q); side margins of carapace distinctly con verging 
posteriorly. Penultimate segment of abdomen of © narrow, only 
slightly broader at the posterior margin than long. 
Superior and anterior border of arm of cheliped wholly unarmed. 
Meropodites of walking legs rather slender, more than twice as long 
as broad. Large species, distance between external orbital angles rea- 
ching to 40 mm. 34 
Carapace either naked or with sparse tufts of hair, in the neigh- 
bourhood of the postfrontal lobes and on the hepatic regions; distance 
between external orbital angles about equal to that between epibran- 
chial teeth. 35 
Posterior margin of carapace shorter than breadth of front, at 
least in the {/; ratio of Gen breadth of carapace to length as 
£00}: SS): Ses. meinerti de Man. 
Posterior margin of carapace longer than breadth of front; ratio 
of greatest breadth of carapace to length as 100: 79.4 ?). 
Ses. rotundifrons A. Milne-Edwards.

The difference between this species and the preceding remains doubtful, so long as 
nothing more definite is known about the species of Milne-Edwards, On p. 173 of the present 
paper I have pointed out, that also in the Q of Ses. meinerti the length of the posterior margin 
of the carapace may be longer than the width of the front between the eyes.
