    In the same volume there is a paper by C. G. Cams on the seminal tube of the Sepia; in which he describes and figures a very complex organization, which as certainly belongs to an entozoon, probably a trichocephalus, as it does not belong to a spermatozoon. Carus had commissioned a friend near the sea shore to send him some of the seminal tubes of the Sepia for examination; the friend must have sent a bottleful of entozoa instead. An excellent notice upon the semi- nal tubes of Sepiae may be seen in the Ann. des Sciences Naturelles, No. for April, 1840, by Mr. Milne Edwards. These tubes are undoubtedly the cysts in which spermatozoa appear to be universally developed, in a persistent state. The writer quoted compares them very aptly to the pollen-capsules of plants, and proposes the title Spermatophores for their designation. R. W.] END OF PART I.
