On account of the small size of the specimens the determination is somewhat 
uncertain. The “palettes” bear a great resemblance to the figures by Wricur (loc. cit.). 
Note. At Singapore in shallow water a solitary valve of a Nausitora has been 
taken (by Sy. Gap), probably N. edax, Hedley (Proc. Linn. Soc. New South Wales, IX, 
1894, p. 501, pl. 32, figs. 1—5), but as its palettes were not found, the determination 
is uncertain.

Distribution: — China, Borneo, Flinders Passage (North Australia). 
The present species is very characteristic on account of its flatness, but like 
all the species belonging to the genus Pandora it varies considerably in form. 
HEDLEy evidently does not know Sowersy’s figure in REEvE’s Conchol. icon. as he 
calls it (Proc. Linn. Soc. New South Wales, vol. 31, 1906, p. 473) an “unfigured 
species” and (loc. cit. pl. 37, fig. 16) gives a figure of a form from Mast Head Reef, 
Queensland, under the name of C. elongatus, Carp., which, however, scarcely is 
CARPENTER’S species. 
Note. Myodora trigona, Reeve, has been taken (by Sy. Gap) at Singapore in 
shallow water.
