本文描述了两种尺寸范围的虹鳟鱼（标准长度12-15厘米和20-23厘米）上颌牙齿替换的模式，这是根据每周两次在麻醉鱼上采集的牙列蜡印来确定的。在上颌前排/上颌排和下颌排/腭排之间，鱼之间的替换波（在牙齿图表上构建的线连接交替牙齿的出牙时间）的性质有相当大的差异。所获得的波型表明，任何一种动物的形态都具有相同的一致性，当连续的几代动物的寿命呈现恒定或按比例变化时，这种一致性是可以预料到的。给出了有关牙齿寿命的数据。结果与下颚的结果进行了比较，并讨论了波形的意义。
The present paper describes the pattern of tooth replacement in the upper jaw of two size ranges of rainbow trout (standard lengths 12–15 cm and 20–23 cm) as determined from wax impressions of the dentitions taken twice weekly on anaesthetised fish. There was considerable variation in the nature of replacement waves (lines constructed on dental charts linking eruption times of alternate teeth) between fish for both the premaxillary/maxillary and vomerine/palatine rows. The wave patterns obtained showed the same consistency of form for any one animal which is to be expected when consecutive generations show constant or proportionately changing life spans. Data relating to the life span of the teeth is given. The results are compared with those derived for the lower jaw and the significance of wave form discussed.
