Report p. 75. Revd Th. Hincks

"on a peculiar organ which occurs in some of the Marine Bryozoa"— has seen several times masses of spermatozoa in Spring poured out through an intestacular orifice.—

[Natural selection, p. 46: "Again Prof. Huxley informs me that he should have thought that the hermaphrodite Bryozoa or Polyzoa (certain corallines) would have offered insuperable difficulties to an occasional cross, had it not been for Mr. Hinck's observations, who saw in some species the spermatozoa pouring out from pores between the tentacula; & as Prof. Huxley remarks what could this be for, except to fertilise some other individual.
