85 Sides of carapace parallel in their anterior half (slightly concave 
behind epibranchial teeth); distance between external orbital angles 
larger than or equal to that between epibranchial teeth. Middle-sized 
species, distance between external orbital angles 15—20 mm. 36 
Sides of carapace not parallel; distance between external orbital 
angles nearly always less than that between anterior epibranchial 
teeth. 37 

36 Anterior margin of front with a rather narrow and deep emar- 
gination; abdomen of © very broad, posterior margin of penultimate 
segment more than three times the length of this segment (save in 
subsp. crassimana de Man). Wrist of cheliped produced at inner angle; 
inner surface of palm granulate, without transverse crest. 
Ses. edwardsi, de Man '). 
Anterior margin of front nearly without median emargination ; 
abdomen of co much narrower, posterior margin of penultimate seg- 
ment about twice the length of this segment. Inner angle of wrist of 
cheliped obtuse; inner surface of palm with transverse gra- 
nular crest. Ses. moeschii de Man. 
37 Carapace flattened, smooth and shining, with indistinct regions. 
Small species, distance between external angles 10—11 mm. 38 
Carapace vaulted, granulate or hairy, with distinct regions. — 39

of front nearly wholly straight. Ses. laevis A. Milne-Edwards. 
Ratio of breadth of carapace (at anterior epibranchial teeth) to 
length as 100: 84.2; anterior margin of front emarginate ; side margins 
of carapace converging posteriorly. “Upper surface of palm flattened,

Legs rather robust, shortened and thick; propodites of walking legs about twice as long (in
