记录了为期9个月的22种裸鳃科动物的季节分布数据。在同一时期，这些动物在实验室水族箱中的交配和产卵的发生被记录下来。这些数据表明，某些物种的季节分布很明显，而且在许多情况下有一个明确的繁殖季节。描述了这些裸鳃动物卵带的特征，并通过照片进行了描述。这些蛋带接近阿基米德螺旋的数学形式。在观察到的每一种情况下，从背面看，条带都是逆时针方向沉积的。讨论了这些观察结果与早期关于裸鳃生物生活史的研究工作之间的关系。
Data concerning the seasonal distribution of twenty‐two species of nudibranchs are recorded for a period of 9 months. The occurrence of copulation and of egg laying for these animals in the laboratory aquaria is recorded for the same period. These data indicate that the seasonal distribution of certain species is well marked, and that there is in many cases a definite breeding season.The characteristics of the egg ribbons of these nudibranchs are described, and figured by means of photographs. These egg ribbons approach the mathematical form of a spiral of Archimedes. In every case observed, the ribbon was deposited in a counter‐clockwise direction, viewed dorsally.The relationship between these observations and earlier work on the life histories of the nudibranchs is discussed.
