The remarkable specimen dealt with in this paper was discovered by Mr. R. May, of Downing College, Cambridge, in the earlier part of the year 1922, and was forwarded to me by Mr. Henry Woods, F.R.S., for study and description. Mr. Woods informs me that “the specimen was found in the Boulder Clay of Hertfordshire, and consists of a portion of a body-chamber of a Perisphinctoid Ammonite in the matrix of which there are wings of a dragon-fly. The ammonite is, of course, derived. It has been examined by Dr. L. F. Spath, Dr. F. L. Kitchin, and Mr. J. Pringle, each of whom has stated that he believes it has come from the Ampthill Clay (of Corallian age)”.
