oxyrhynch - I could not find dictionary definition, and found only a site mentioning it. The roots suggest it means “pointed nose”:
“Osiris brought wealth, contentment, and civilization to a savage people but was murdered by his brother Set, who cut the body into fourteen pieces and scattered them along the Nile. Isis, Osiris's wife, searched the river until she had recovered every piece of the precious fragments, save for the phallus, which had been devoured by a Nile crab, oxyrhynch, which Egyptians forever curse for this crime. Then, for the first time on Earth, Isis, together with Anubis, performed the embalming rites which restored to osiris eternal life as ruler of the Kingdom of the Dead.
