1717 Philos. Trans. 1714–16 (Royal Soc.) 29 453 The Uterus was of the natural Size without any Alteration, except that the Os Tincæ and Collum minus were fill'd with a gritty Substance, hard as Stone.

1737 Med. Ess. (Edinb.) III. xix. 318 I examined her Condition, and found that the Os Tincæ had..not yielded.

1740 W. Cheselden Anat. Human Body (ed. 5) iv. ii. 271 Its orifice into the vagina, is called os tincæ, from the resemblance it bears to a tench's mouth.

1859 Todd's Cycl. Anat. & Physiol. V. 626/1 This unequal form of the two lips doubtless gave origin to the term os tincæ, by which the older anatomists designated the part.

1934 Philos. Trans. (Royal Soc.) B. 223 271 The upper vagina has been slit open, and the vaginal fluid drained off, to reveal the corrugated lining and the projecting os tincæ.
