I must particularly guard against the inference from this specimen that any of the sandstone-nodules are of Eocene age ; the scute is water- worn, and its occurrence in the sandstone is sufficiently explained as above.

III. A new Ziphioid Cetacean from the Suffolk Bone-bed (Choneziphius Packardi). Pl. XXXIII., figs. 1-4.
The fossil about to be described was found lying by the side of a crag-pit near Felixstow, Suffolk, and was for many years in the collection of the lady after whom Nucula Cobboldioe was named. It has lately been presented by Mr. Cobbold, with some other fossils, including a wonderfully fine specimen of Pleurotoma intorta, to the Ipswich museum, that institution having during the past year, through the exertions of Mr. Edward Packard, Mayor of the town, been much enlarged and extended in its series of crag fossils. Mr. Packard has given some very valuable specimens from his own collection to the museum, besides contributing largely to the expense of arranging the collection and filling up gaps in the suite of crag mollusea.
The specimen is exceedingly heavy, and is in precisely that mineral condition which characterizes the cetacean bones from the Suffolk bone-bed, and which demonstrates them to have lived, not in the crag sea (the proper cetacean remains of which are pulverulent, as I pointed out in the Quart. Journ. Geol. Soc. 1865, p. 223), but
