Oscar Schmidt's Remarks upon with a bud of medium age, which showed me the ventral surface, and the seminal vesicle gorged with spermatozoids. While I was taking a sketch of it with the camera lucida the whole twisted packet of spermatozoids contained in the vesicle was suddenly expelled by a violent contraction of the entire animal. The packet slipped rapidly forward behind the peri- stome, and appeared free in the cavity of the vestibule between the tentacles. After a few minutes the animal closed the tentacular curtain with a jerk ; the packet was then shot out into Fig. Reproductive organs of Loxosoma pes. r, margin of the body; o, ovary; v, seminal vesicle; t, testes; g, seminal ducts; A-, bud-cell-stock ; /, bud-pit. the water, and escaped my subsequent researches. After this expulsion the seminal vesicle, which was before so prominent, could only be distinguished with the greatest difficulty, it was so collapsed. As to the canal by which the seminal packet must have passed to reach the bottom of the vestibule, I found it impossible to distinguish ; I have cited this whole passage (which is supposed to prove that a transfer of the semen outside the body takes place by means of the water) because I can furnish a very simple explanation of it. As early as 1875 I observed (and the drawing and notes upon it are now before me), in Loxosoma.
