1. 概述了有关蜘蛛交配行为的基本事实以及该行为进化起源的主要理论。需要指出的是，这些都无法解释为什么精液在被雄性触肢器官吸收之前首先沉积。 2. 对已知事实的蛛形纲动物的交配习性进行的比较调查表明，原蜘蛛可能通过沉积在基质上的精囊将精子转移给雌性。触须最初可能有助于此操作或仅保持女性生殖孔的打开。进一步表明，精囊的损失和精液沉积模式的保留与结网的进化有关。
1. The essential facts concerning mating behavior in the spiders are outlined together with the main theories of the evolutionary origin of this behavior. It is pointed out that these fail to explain why the spermatic fluid is first deposited before being taken up by the palpal organs of the male. 2. From a comparative survey of the mating habits of those arachnids for which the facts are known, it is suggested that the proto-spiders may have transfered the sperm to the female by way of a spermatophore which they deposited on the substratum. The pedipalps may initially have assisted in this operation or have merely held open the female genital aperture. It is further suggested that the loss of the spermatophore and the retention of the pattern of deposition of the spermatic fluid are to be correlated with the evolution of web-spinning.
