Abstract
The Collection of Western Australian Cephalopoda which has been handed to me for examination consists of twelve specimens, viz. two Belemnites, one Nautilus, and nine Ammonites. One Ammonite was obtained from Cape Riche, E. of Albany; all the other specimens were collected near Champion Bay. They are chiefly internal casts, and ou the whole are badly preserved: the Nautilus is in a fair state of preservation; but the Ammonites are very imperfect; the suture-line can be satisfactorily made outinonly one specimen, hence the generic determinations must be regarded as only approximate.
