The two hoards of fourth-century Roman bronze coins here described were obtained in Egypt by Professor Petrie: and, as they cover a period on which not much work has been done, a detailed account of their contents may be of value.

The classification adopted is by means of reverse types and mints. It does not seem necessary to refer at length to the obverse types, which exhibit little variation in most reigns concerned: any points of interest are mentioned in the notes prefixed to each list. The types are arranged in what appears to be their chronological order: the earlier issues, mainly of Constantinus I and his sons, which are represented only by stray specimens, are grouped together.
