Crustacea Decapoda and Stomatopoda.

A single female with carapace mm. in breadth was obtained by Dr. Annandale 
at the edge of the Whangpoo R., 5 to 10 miles below Shanghai. It was found in a 
burrow above the water-line in mud which was rapidly hardening. The water in 
the river at the point where the specimen was taken is quite fresh at all seasons. 
The species is readily distinguished from T. stapletoni, de Man, by the characters 
given by Miss Rathbun ; it has been recorded from Shanghai, where the type speci- 
mens were obtained, and from Korea.

Dr. Tesch has recently redescribed this species. In the account which I pub- 
lished in 1915 I placed the genus in the Grapsidae and in the subfamily Varuninae, 
being under the impression that it was remotely allied to Eriocheir. Dr. Tesch, who 
has had the advantage of examining an adult male, considers that it belongs to the 
Ocypodidae and to the subfamily Macrophthalminae and is not distantly related to 
Paracleisto stoma. With this view I concur. 
. Two females of this rare species, with carapace 7 2 and 67 mm. in breadth, were 
found by Dr. Annandale in the Tale Sap. They are a trifle smaller than the dead 
female found in the Chilka I^ake {v. Kemp, he. cit.. text-fig. 13) ; the sculpture of the 
carapace is crisper, the transverse ridge on the branchial and cardiac regions being 
more sharply defined and the antero-lateral teeth more prominent. 
The specimens were found in the channel opposite Singgora on a bottom of mud 
and dead shells at a depth of 4^ metres and in the middle of the outer lake, N. of Koh 
Yaw, on a bottom of sticky mud at a depth of 2\ metres. The specific gravity 
of the water in the former locality was i 00625 and in the latter 10035 (corrected). 
The species has been recorded from Hong Kong (Stimpson), the Bay of Batavia 
(Tesch), the Chilka I^ake, Orissa (Kemp) and Ennur backwater, Madras (Kemp).

A single dead specimen with carapace 34 mm. in breadth was found at the mouth 
of the Tale Sap. The species is probably not an inhabitant of the lake.
