The Boko is the same as that which is called Panju by the Malays. 
It is the common sea-tortoise, which is of no other use than to be 
eaten. To these sorts the Panjubui ought to be added, being the 
common tortoise with a thick shell, like that of the proper tortoise, 
but of poor quality and therefore of trifling value ; so also the Akung 
Boko, which is. distinguished from the common Boko by its much 
larger head. 
The Ratu, lastly, furnishes a sort which is distinguished by its 
peculiarly great size, the Orang Bajos asserting that it is usually 
twice as big as the largest tortoise-shell tortoise, and therefore 5 to 
6 feet long, and even more. 
The usual modes by which the Orang Bajos catch the tortoise 
are principally by the hadung, the harpoon and the net; to these we 
add the simplest of all, namely falling upon the females when they 
resort to the strand to lay their eggs. ‘This is also the most usual, 
[ may almost say the only way, by which the inhabitants of the 
coast catch this animal. They need nothing more, than, as soon as 
they have got the creature, to turn it on its back, when, unable to 
turn itself again, it remains lying helpless in their power. It some- 
times also falls into the hands of the dwellers on the coast through 
means of their fishing-stakes, into which it enters like the fish, and 
from which it can find no outlet, but remains imprisoned in the 
inner-most chamber. 
Whenever the Orang Bajos have caught a tortoise, they kill it 
immediately, by bestowing some blows upon the head. ‘They then 
take its upper shield, or the back itself quite off, being the only thing 
about the animal which is of value. ‘he tortoise-shell adhering so 
fast to the shield, that, if they at once pulled it off, there would be 
danger of tearing the shells, they usually wait three days, during 
which time the soft parts become decomposed and the shells are 
loosened with little trouble. When they wish to remove the shell 
immediately after the capture, they separate it by means of boiling 
water. They also often accomplish this object by the heat of a fire, 
in the application of which, however, a danger is run of injuring the 
shell by burning it, for which reason this mode is only adopted by 
those who do not know its value. —Journal of the Indian Archipelago

Notice of some Mollusca recently taken by George Barlee, Esq., off 
Lerwick, and exhibited at the Meeting of the British Association for 
the Advancement of Science, 17th Sept. 1849. By J. G. Jerrreys, 
Esq., F.R.S. 
Diphyllidia lineata, Otto. New to the British seas, but (according 
to M. Milne-Edwards) only one-fourth the usual size. 
Rissoa eximia, nov. sp. Shell oblong, rather solid, white. Whorls 5, 
the last equal in length to all the rest, rather swollen and ribbed 
longitudinally. The ribs are sharp, deep, and curved in the direction 
of the spire. ‘There are about twelve of therm on the last or body 
whorl. The two first whorls are destitute of ribs or any markings.
