The spider, Chiracanthium japonicum, has been well recognized as poisonous by common people in Japan. Especially in Tohoku, North Japan, this species has been most feared of toxic spiders and named "Kuchiguro" because of having black jaws for killing or paralyzing their prey. Eleven cases of arachnidism caused by this species were recorded during the periods from 1973 to July 1975. In the present paper, an analysis was made on total nineteen cases of arachnidism including the eight cases which had already been reported since 1956 in Japan. Results were as follows : 1. Arachnidism caused by Chiracanthium japonicum occurred from May to August with a marked peak in June. 2. Arachnidism in males was more frequent than in females and most frequent bites occurred in teenagers. 3. It was remarkable that many cases of arachnidism occurred during sleep at night by male spiders which were infesting houses. 4. The site of bites was most frequently observed in upper extremities. 5. The symptoms of arachnidism were characterized by local skin legion as continuous sharp pain, erythema, swelling, petechiae and pigmentation, and frequently combined with generalized signs of nausea, vomiting, loss of appettite, headache and shock. 6. In treating the arachnidism, it was a serious problem to relieve continuous sharp pain of biting area. The use of central analgesic such as narcotic drugs seemed to be effective.
