Origin: Formed within English, by compounding. Etymons: ovi- comb. form¹, cell n.¹

Etymology: < ovi- comb. form¹ + cell n.¹ N.E.D. (1904) records also a Latin form ovicella. N.E.D. (1904) gives only the pronunciation (ō^u·visel) /ˈəʊvɪsɛl/.

1. Zoology. A rounded chamber, projecting from the wall of a zooecium, in which the early embryos of some bryozoans develop. Also called ooecium.

1856 T. H. Huxley in Q. Jrnl. Microsc. Sci. 4 192 The ovum passes..into the ovicell—there as in a marsupial pouch, to undergo its further development.

1870 G. Rolleston Forms Animal Life 71 Broad-leafed Hornwrack... The ovicell, a sort of marsupial pouch,..is inconspicuous in this species.

1877 T. H. Huxley Man. Anat. Invertebrated Animals viii. 458 They sometimes..undergo the first stages of their development in dilatations of the wall of the body, termed ovicells.

1927 Q. Rev. Biol. 2 402/2 The fertile zooecium then develops into an ovicell, which serves as a brood chamber for the developing embryos and larvae.

1950 R. W. Miner Field Bk. Seashore Life xiv. 819 The ovicell [of Schizoporella unicornis] is nearly spherical, with a punctured surface, often with radiating grooves.

1987 M. S. Laverack & J. Dando Lect. Notes Invertebr. Zool. (ed. 3) xxviii. 165/1 Some developmental evidence exists for a hormone controlling the formation of ovicells (brood chambers).

†2. Biology. An egg cell; an ovum. Obsolete.
