The sound of Koh Chang, 3—5 fathoms (fragment). 
Distribution: — Malacca, Tranquebar, Bombay. — Philippines, China, Korea, 
Japan. 
Although I am almost convinced of the correctness of the determination, yet, 
on the basis of the small fragment of a young individual which is at hand, it 
cannot be settled with complete certainty, if the specimen does not possibly belong 
to the nearly allied species Sil. Winteriana, Dunk.

North of Koh Kahdat, 4—5 fathoms, coarse sand (!/2). 
Long. 85 mm., alt. 18 mm. 
Distribution: — Nicobars, Moluccas, Viti Isls., Kingsmill Isls. 
The figure in “Donum Bismarckianum” is not quite good; the outline both 
in SPENGLER’s original specimen and in the specimen from Koh Kahdat is more 
squarish-oval, the anterior and posterior margins being almost rectilinear, obtusely 
truncated, and forming rounded angles with the dorsal and ventral margins.
