of low islands. The Radackers catch it by torcli- 

 light, in the night. There are several sorts of 

 fish which are not eaten, and are considered as 

 poisonous. Kadu mentioned instances of persons 

 poisoned in this manner. These species are eaten 

 at Ulea, after a certain internal part (the liver ?) 

 has been taken out ; and several (for instance, the 

 Diodon and Tetrodon species) are even considered 

 as dainties. Among the poisonous fish at Radack, 

 two rays (Rqja) are mentioned, which attain an 

 extraordinary size ; one of them has, like the Raja

 when they are lost, they grow again within twenty 

 days. They are always taken hold of before. 

 They are pursued on account of their skin, which 

 is used to cover drums. Both species are eaten at 

 Ulea. 



There is a great variety, both of univalve and 

 bivalve shells. Many of them are eaten, and the

 ChamagigaSi and other large bivalve shells serve 

 as vessels, and are also used as instruments for 

 cutting : the mother-of-pearl is sharpened into 

 knives; and smaller kinds of snails are worn as 

 ornaments, in elegant rows, round the head and 

 neck. 



Among the crabs, we noticed several small
