C. Bonner, Amulets Chiefly in the British Museum, Hesperia 20 (1951), 301-345, no. 33.

Obv. Harpocrates seated to r. on lotus capsule in a papyrus raft, on each upturned end of which a crowned hawk perches. The young god has a disk on his head, and with both hands is holding a clarinet like instrument; but the mouthpiece is not between his lips, which are clearly seen below it. Perhaps, as an expert on ancient music has suggested to me, the god has removed the instrument from his lips in preparation for a phrase of song.
Rev. Round the margin, fourteen signs including a Greek delta and two possible omegas; the rest meaningless characters or else cryptographic signs. Within these, a spiral inscription reading inwards, δὸς χάριν Θεανοῦτι πρὸς Σεραπάμμωνα, "grant Theanous favor in the eyes of Serapammon." Both names are several times attested in Egyptian papyri. Theanous is an Egyptian variant of Theano.
Bloodstone. Transverse oval, 25 x 21. The stone was briefly described, without an illustration, in SMA, p. 48. See the next number.
