This is the Goddess Nephthys
Nephthys was the Goddess of death & service.
She is the daughter of Nut and Geb. Nephthys was typically paired with her sister Isis in funerary rites because of their role as protectors of the mummy and the god Osiris and as the sister-wife of Set. Nephthys plays an important role in the Osirian myth-cycle. It is Nephthys who assists Isis in gathering and mourning the dismembered portions of the body of Osiris, after his murder by the envious Set. Nephthys also serves as the nursemaid and watchful guardian of the infant Horus.
Nephthys is also the mother of Anubis.
