specimens of tusks from the bed are one fragment in the British Museum, and one very small fragment in Mr. Whincopp's collection.
5. Cervus, sp. The teeth and horns of Cervine animals from this bed are abundant in collections, and indicate several species, which cannot be considered as having been at all satisfactorily determined. Portions of jaw with teeth in situ are occasionally found. There is such a specimen in the British Museum. The collections already mentioned contain each a few specimens which are important in attempting to work out the Cervi of this deposit. Mr. Canham has two fine molars of the large form, which was assigned by Professor Owen to Megaceros. Each of these collections contains also one or two teeth of
6. Hipparion, sp.
7. Equus, sp.
8. Castor veterior, Lankester, figured by me in the ' Annals and Magazine of Natural History,' 1864, is represented by two molars and an incisor in Mr. Whincopp's collection.
9. Ursus arvernensis, Croizet and Jobert, is represented by a single canine in Mr. Whincopp's collection.
10. Fells, sp. Besides the fragment of a molar figured by Prof. Owen in the ' British Fossil Mammals ' as Felis pardoides, and now in the Ipswich Museum, I have observed in Mr. Canham's collection a very perfect upper last premolar of a feline animal of the same size, also a similar tooth, more worn, in Mr. Baker's collection. These teeth have the fangs preserved.
11. Hyoena antiqua, Lankester. Three specimens now represent this species, indicated by me in the ' Annals and Magazine of Natural History,' 1863, — one upper third premolar now in the British Museum, for which collection I purchased it at Felixstow ; one lower third premolar in Mr. Whincopp's collection, much worn ; lastly a very perfect specimen of another upper third premolar like the first, of a much deeper stain, however, and somewhat more mineralized, in the collection of Mr. Baker at Woodbridge (Pl. XXXIII. figs. 5, 6).
12. Mastodon (Trilophodon) sp. (tapiroides?, Cuvier). Perfect enamel crown of left upper penultimate molar in the collection of Mr. Baker of Woodbridge ; fragments in Mr. Whincopp's, Mr. Canham's, and the British Museum collections.
The preceding paragraphs will give some notion of the fragmentary character of these remains, which would never have been known at all but for the careful sifting for phosphatic nodules of the bed in which they occur.
VI. List of Marine Mammalia from the Suffolk Bone-bed, with. REFERENCE TO THE NUMBER OF SPECIMENS AND THE COLLECTIONS CONTAINING THEM.
1. Trichecodon Huxleyi, Lankester. Fragments of the tusk of this species are in nearly all collections. The finest I have seen are in Mr. Whincopp's and Mr. Baker's collections, who have portions of the base more than a foot long.
