Near Koh Samit and Koh Tulu (boring in the swampy layer of cocoanuts 
which float upon the surface of the water). West of Koh Chang (boring in the 
fruits of Terminalia Catappa L., which float upon the surface). 
Only small specimens as much as 5 mm. in length. 
Between Bangkok and Kampot in the Gulf of Siam (MorRLer). 
Distribution:— Singapore, Pulo Penang, Mergui Archip., Burma (in the 
trunks of the teak-tree), Madras, Tranquebar, Gulf of Manaar, Bombay, Aden, Ins. 
Zanzibar, Mozambique. — Annam, southern China Sea, Japan, Philippines, Borneo, 
Batavia and Molluccas (in piles), Arafura Sea, Cape York, Cooktown (Queensland), 
Sydney, New Caledonia. — East coast of America: South Carolina, Florida, 
Bermuda Isls., Texas, Greater and Lesser Antilles (Guppy and Gass record it from 
pliocene formations on Trinidad and in Costa Rica), South America as far as Rio 
de Janeiro. — The coasts of Europe, e. g. along England and France and in the 
Mediterranean it has been taken in floating timber and boring in ships. 
SPENGLER’S Original specimens! of P. lignorum from Tranquebar agree precisely 
with the specimens of P. striata L. from St.Thomas. Several other boring forms 
such as Naranio lapicida, Chemn., Coralliophaga coralliophaga, Chemn., Modiolaria 
coralliophaga (Chemn.) Gmel., Lithodomus cinnamomea, Chemn., and others have 
almost the same wide and peculiar geographical distribution as the present species. In 
the above-mentioned cocoanut from Koh Samit many quite young, living specimens, 
3--5 mm. in length, were found, without Callum, and of the accessory plates only 
a “Protoplaxe” is found, which in form differs from those of the full-grown 
individuals. *
