Cases of polconliv! reported for Vu-lS spec-es are all li'^ht, involving 

 slight Impairment of the sensory or locomotory functions even where rather 

 large quantities have been consumed. The save est cases recover in three 

 or four days and no deaths were reported. 



The followinp; conclusions are drawn from the above information: 



Fish under 40' cm in length are nonpoisonous , Fish over 70 cm long are 

 mildly poisonous. Those In between are slightly poisonous, however, it is 

 thou^t that there must be considerable variation depending on the indi- 

 vidual fish and on the Individual eating the fish so, except for those 

 which are only slightly poisonous (those which may be eaten without serious 

 trouble), it would be safest to eat only fish under 40 cm long. 



2. Wlramlhlraa.1i (Plate 4 Figure U) 



Scientific name - Caranx leseonll ' Cuvier f- Valenciennes 



Local name - ndnd^nagara (Okinawan). lkubu.1 (old fish, ?larshallese), 



kubkub (Immature fish, !Iarshallese) 

 Distribution - Indian Ocean, tropical Pacific, Formosa 



"orpholcgy - Eye much larger than preceding species, enslly distinguishable. 

 Mouth also large, posterior end of maxillary extending as far as posterior 

 edge of eye. First dorsal VIII; second dorsal II, 20-21; anal II / I, 

 ^.6-17.

Scutes on straight portion of lateral line, 30. loes not reach a large size, 

 the largest seen by the author being about 20 cm [siej . Can be readily 

 distinguished from the preceding species by the characteristics listed above. 



Toxicity . Three specimens (51 cm, 49 cm, and 23 cm in length) ^ere 

 tested. Toxicity was marked in all but the 23 cm one, 17.5 gr of flesh pro- 

 ducing conspicuous symptoms of poisoning in a cat neighing 0.8 kg. "/ith the 

 specimen 23 cm long, 37 gr of flesh caused no ill effects in a cat ;\ieighing 

 0.3 kg, and although" only one test was made with this specimen, it appears 

 that In this species, as In the preceding one, only large fish are poisonous. 



The Marshallese draw a strict distinction between large and small fish 

 of this species, believing them to be different species. They call large 

 ones lkubu.1 and small ones kubkub . Ikubu.i are considered poisonous, while 

 kubkub are a staple food fish. As the plate shows, the coloration of the 

 (Page 38] IkubuJ is darker than that of the kubkub and it looks .like an 

 altogether different species. Nevertheless, not only can no important 

 morphological difference be detected (slight differences in body depth and 

 eye diameter are probably due to age difference^, but specimens of an in- 

 termediate size show an intermediate coloration, anc^ so they ar^ considered 

 to be the same species. 



Natives, when shown fish of various sizes, identified as kubkub those 

 below 30 cm In length. 



According to the results of experiments with animals, specimens less 

 than 30 cm in length may be eaten, but those of around 50 cm must be con- 

 sidered strongly toxic. 



Besides the kubkub the natives say that two other species of caranglds, 

 the rewa and the aron . are eaten, but xie were unable to collect them. It
