תּוספֿתּא אויף ויקרא 21:18

What is [considered] "extra"? Any [animal] that has three eyes or five legs. [What is considered] "missing"? Three legs or one eye. What is "unfit"^*pasul; alt., kasul (Jastrow)? Any [animal] whose loins (k'salim) protrude. [If] most of its ribs were broken, or if he had in it a blemish from within, it is not a [disqualifying] blemish, as it is said (Lev. 21:18), "blind or lame," What is "blind or lame"? Specifically, a blemish that is openly visible and does not revert to its former state. Said Rabbi Yosei ben HaMeshullam, Ila (see Bekh. 6:8) would count blemishes in Yavneh and state them before the Sages, and they agreed with him. And another three he added. They said to him, "We have not heard about any one of these: That the eyeball is round like that of a human, and its mouth is like that of a pig, and that most of its tongue has been removed." And Rabbi Chananiah ben Antigonos said, "Most of the speaking part of the tongue." The Beit Din that came after them said, behold, these are [indeed] blemishes. The lower lip protrudes over the upper: Behold, that is a blemish. Rabban Shimon ben Gamaliel says, if the upper [lip] protrudes over the lower one, like that of a pig, behold, that is a blemish. [If] its mouth is swollen or its leg is swollen^*מובלמות (see Bekh. 40b:5, Minchat Bikkurim here), on its own accord, it may be slaughtered; on account of the wind, it may not be slaughtered. [If] its ears were closed up with a single cartilage, it may not be slaughtered; with two cartilages, it may be slaughtered. Rabbi Chananiah ben Gamaliel says, the tail of a ewe that has three vertebrae in it, it may not be slaughtered; two -- it may be slaughtered. The tail of a calf that does not reach to its "joint" (arkov), behold, this one may be slaughtered. To which "joint" did they refer? Rabbi Chananiah ben Antigonos says, to the joint that is in the middle of the thigh (Bekh. 6:11), until the upper joint, and not until the lower joint.
