CIMRM 91, 92 and 93 - Tauroctonies from Hermopolis and Memphis, Egypt.
Four reliefs of the tauroctony are known from Egypt. Three are all displayed together in the Cairo museum, the fourth is in Berlin.
CIMRM 91 (JE 85747) is a marble relief of a tauroctony discovered, not at Memphis in 1885 as Vermaseren says, but at Hermopolis (al-Ashmunein) and sent to Cairo in 1941 by the inspector at Asyut.1 The mistake arises because the three were grouped together at the Cairo museum, and appears elsewhere in the literature. The photo given as fig. 34 in Vermaseren in fact relates to CIMRM 92.

An additional tauroctony, probably from Hermopolis, is described by Harris:
CIMRM 92 and 93 come from Memphis. In 1885 Grebaut discovered some Mithraic finds at Memphis. No proper excavation was done, nor was any report made. The two finds have become confused by arriving at the Cairo museum at the same time.2
Cumont lists the two Memphis tauroctonies, and gives photographs of both, made by Emile Brugsch, the museum director at the time, which allows us to discover Vermaseren's mistake. There is no indication that Cumont had seen the items.
