ZOOIvOGY OF THE FAR EAST. 
It should be noted that the specimens from Mergui, recorded by de Man in 1888 
under the name 5. livida, have since been described by him as a new species — S. 
onychophora . '

A single specimen, with carapace 8 6 mm. in breadth, was obtained by Dr. 
Annandale at Kantang in Trang, on the west coast of peninsular vSiam. It was 
caught running on the piers of the landing stage above water-level.

Two males and one female, the largest with carapace mm. in breadth, were 
foimd in the Patani River in the Siamese Malay States. The specimens were obtained 
in fresh water, but in a locality subject to tidal influence.

Two males from Shanghai are referred to this species. The carapace of the 
larger is 27 mm. in length and 31 mm. in greatest breadth ; that of the smaller is 
i7\5 mm. in length and 20 "8 mm. in breadth. In 
both specimens there is a single well marked tooth 
on the lateral margin behind the extra-orbital 
angle, but further back there is scarcely a trace of 
a rudimentary third lateral tooth, such as has 
been described in certain Sesarma referred to this 
-Species. 
The crest on the upper margin of the merus 
of the chelipedes does not possess a subterminal 
tooth, as in S. tetragonum ; the upper surface of 
the carpus is smooth and its inner margin bears a 
few small tubercles, but is not toothed. The up- 
per margin of the palm is defined by an obscure 
and feebly crenulate ridge ; its outer surface shows 
only the slightest traces of rugosity, but bears the 
oblique longitudinal line referred to by Tesch. 
The fingers are smooth except for a .slight tubercu- 
lation on the dorsal surface of the dactylus near its 
proximal end . In both specimens the fingers gape, 
meeting only at the tips, the extent of the gape
