申命记 14:7

השסועה — (lit., a cleft one) is a certain animal which has two backs and two spinal columns (Chullin 60b). — Our Rabbis asked, “Why are these (the clean and unclean beasts and fowls) here repeated” since the names have already been mentioned in Leviticus XI? They replied: the repetition was necessary so far as quadrupeds are concerned because of the שסועה, and so far as fowls are concerned because of the ראה, both of which are not mentioned in Torath Cohanim (i.e. Leviticus) (Chullin 63b).

אַ֣ךְ אֶת־זֶ֞ה לֹ֤א תֹֽאכְלוּ֙ מִמַּֽעֲלֵ֣י הַגֵּרָ֔ה וּמִמַּפְרִיסֵ֥י הַפַּרְסָ֖ה הַשְּׁסוּעָ֑ה אֶֽת־הַ֠גָּמָ֠ל וְאֶת־הָאַרְנֶ֨בֶת וְאֶת־הַשָּׁפָ֜ן כִּֽי־מַעֲלֵ֧ה גֵרָ֣ה הֵ֗מָּה וּפַרְסָה֙ לֹ֣א הִפְרִ֔יסוּ טְמֵאִ֥ים הֵ֖ם לָכֶֽם׃

Nevertheless these you shall not eat of those which chew the cud, or of those which divide the cloven hoof; the camel, and the hare, and the coney: for they chew the cud, but do not divide the hoof; therefore they are unclean to you.
