摘　　要：枕鳞的顶间部为膜化骨,其骨化中心共六对,排列成上、中、下三列。上列为左、右各一个骨化中心,能转化为前顶间骨;中列分内、外两对骨化中心,能转化为顶间骨;下列为三对骨化中心。在中列骨化中心和下列骨化中心之间为枕横缝出现的部位。The interparietal bone in 385 cases of fetal skull aged different prenatal months were observed by stereoscope after alizarin staining and transparent hyalinization. Six pairs of the ossific centres in membrane were found in the interparietal part of the occiptal bone. The upper pair of ossific centers may develop into preinterparietal bone. The two middle pairs may become interparietal bones which commonly vary greatly. The suture occipitalis tansversus is extended between the middle and the three lower pairs of ossific centers, and the latter is different from that described by some investigators.
