Toadcity . Of the 4 cats used in the experiment, 2 which ate cooked 

 flesh and one which ate raw flesh showed extremely slight sensory and 

 locomotory Impairment, Of 9 mice only one showed functional impairment 

 of the hind legs. 



Judging by these results this species may be said to be slightly 

 poisonous. Tfetsuo's paper is the only known example in the literature 

 which cites this species as being as poisonous as the preceding species. 



According to some ^!arshallese, only the fish taken at Jabor island 

 in the Jaluit atoll are slightly poisonous while those taken at the other 

 islands are nonpoisonous . The toxicity of specimens from Jabor was of the 

 degree described' above. The natives appeared to have no qualms about 

 eating this fish, and, while informing the author that it was poisonous, 

 went right on eating it. The llarshallese distinguish this species by a 

 separate name from the preceding species, which th^ do not eat. TTost of 

 Japanese apparently make no distinction between these two species of 

 barracuda. 



[Page 3lj Section 4 Genus Caranx 



T!ost of the many species of the genus Caranx. family Carangidae, are 

 useful foodflsh and are handled as a high-grade article in fish markets 

 in Japan and all over the world, 



A very few of these species have been considered poisonous for many 

 years. According to Pellegrln*, Caranx' f allax is poisonous at Havana, 

 He also records C. plume ri as poisonous, specimens containing poison be- 

 ing said to have red bones. Poey (op. cit. p, 25) also records Seriola 

 glgas and Seriola lalandi of the closely related Serlolidae as being 

 poisonous in Cuban waters, 



Althou^ these species are very sLnilar to the seriollds and earangids 

 of Japan, we have heard of no cases of poisoning caused by these fish in 

 this country. 



The' species of earangids inhabiting the South Seas area are vexy 

 numerous, probably over 100, and it was impossible to collect and test 

 them all in the short time at our disposal so we omitted those species 

 which are commonly used for food and investigated only the following two 

 species, which have frequently caused cases of poisoning.
