A puffer fish Fugu flavidus Li, Wang et Wang of Family Tetraodontidae was studied for the first time in Korea. Specimens were obtained from fish markets in Kunsan and Mokpo in February 1985 and June 1989. The Fugu flavidus is similar to F. obscurus and F. niphobles in morphometric characters, but differs from them in dorsal part of the body : yellowish-brown or greenish-brown, and covered with many round white spots which are clear in young and become indistinct as the fish grow. A new Korean name "Hwangjombok" is proposed for the F. flavidus.

Ten specimens of the imported pufferfish, fugu flavidus ('Sarnchaebog'), from China were assayed for anatomical distribution of toxicity, Also, a toxic ovary of each specimen was excised, and transferred into Bio-gel P-2 column chromatography for purification of the toxins. The average toxicity of all specimens assayed was calculated to be $4.1\pm 0.5\;in\;liver,\;2.8\pm1.1\;intestine,\;0.8\pm0.5\;skin,\;2.3\pm1.5\;testis\;39.0\pm16.0\;ovary\;and\;7.0\pm2.0 MU/g$ bile, respectively; Ovary was weakly toxic, but others were non-toxic or weakly toxic. Moreover, instrumental analyses including thin layer chromatography(TLC) and electrophoresis disclosed tetrodotoxin (TTX) and anhydro tetrodotoxin (anh-TTX), respectively. The toxins of the ovary gave four peaks in high performance liquid chromatography (HPLC) whose retention times (14 and 24 min) were close to those of TTX and anh-TTX, respectively.
