314 MR. F, DAY ON THE FISHES OF COCHIN, [Mar. 14, 
Amongst the Gymnodontide the most common are the Tetrodons 
or Sea-Porcupines, as known to Europeans, or “ Kuddul maheut- 
chee’’ (Mal.), Sea Frogs, as they are termed by the natives on ac- 
count of the noise they make when captured. They are taken in 
the Chinese nets on the river’s bank; they are thrown up by the 
sea on the shore, and also captured in brackish and saltwater marshes. 
The natives occasionally eat them; but as they frequently cause in- 
digestion—some allege, symptoms of poisoning—they are generally 
avoided. The native doctors prescribe them in cases of phthisis, 
having a belief in their curative powers for diseases of the lungs.
