Superficial veins of the cubital fossa of 400 upper arms of living Chinese subjects were observed. They were grouped into six types according to Charles and Hashimoto with minor modifications. When the cephalic vein was connected with the basilic vein by means of the median cubital vein, it was classified as type I which took the lead in 56%. When it was connected by means of the "Y"-shaped median antibrachial, median cephalic and median basilic veins, it was classified as type II and was next in frequency (28%). Median antibrachial vein, one to five in number, terminated frequently into the me-dian cubital vein (26%)or the basilic vein (25%). The presence of the two median antibrachial veins in both type I and type II occurred in about 50%. The accessory cephalic vein occurred in 30%; the "Inselbildung" ce- phalic vein occurred in about 25%, being more numerous in type I. The presence of these veins showed a greater incidence on the right side than the left side. In all racial groups, type I was most frequently observed, and type II next. The antibrachial vein usually terminated into the basilic vein or the cubital vein.
