428 H. GOVIER SEELEY ON THE OCCURRENCE OF 



44. Notice of the Occurrence of Remains of a British Fossil Zeu- 

 glodon (Z. Wanklyni, Seeley) in the Barton Clay of the 

 Hampshire Coast. By Harry Govier Seeley, Esq., E.L.S., 

 E.G.S., &c, Professor of Geography in King's College, London. 

 (Read June 21, 1876.) 



In 1872 my late college friend Dr. Arthur Wanklyn, who had for a 

 long time devoted himself to a study of the Barton Clay, was so for- 

 tunate as to obtain, from the Barton Cliff, nearly the whole of the 

 skull of a zeuglodont of moderate size. The skull was extracted 

 entire ; but the local collectors, in carrying it up the cliff, had the 

 misfortune to reduce it to fragments. The day before Dr. Wanklyn 

 was leaving London for professional duties, he desired me to draw up 

 some notice of the specimen for publication ; but the time at my 

 disposal was too brief for me to attempt a full description of the 

 whole of the remains, and I contented myself with some memoranda 

 on the maxillary bones, teeth, and roof of the brain-case. These I 

 have hitherto kept for myself in the hope that Dr. Wanklyn would 

 be able to bring the fossil to London, in a more perfectly restored 

 condition, for fuller study. But the specimen never came ; and 

 since Dr. Wanklyn's death I have been unable to get any tidings 

 concerning it. It has therefore seemed desirable to offer to the 

 Society the notice which I made four years ago ; and I do this the 

 more gladly that it enables me to associate with the species the 

 name of its discoverer, of whose enthusiasm for science this may 

 serve as a slight memorial. 



Maxillary Bones. 



The maxillary bones are imperfectly preserved posteriorly. 

 They show a length of about 8 inches of the bone on the left 

 side, and less than 7 inches on the right side. The anterior termi- 

 nation of the bones is perfect and rounded convexly ; and there 

 they measure transversely across the palate 2| inches from side to 

 side. Each bone in its alveolar surface is about -J inch thick ; and 

 the palatal space between the bones is at present filled with matrix. 

 The external lateral surface of each bone is slightly convex from 

 above downward ; but in length the sides of the bones are concave, 

 because they diverge posteriorly. The alveolar border of the bone 

 preserves for some distance backward approximately the same thick- 

 ness from side to side. 



The fragment shows indications of five teeth on the left side. 

 Between the second pair of tooth-sockets the jaw measures 2% inches 

 from side to side ; at the third pair of teeth it is 3|- inches 

 from side to side ; and then it widens more rapidly behind. There 

 is a strong oblique inner alveolar thickening of the jaw behind the 

 posterior denticulated teeth. These processes are prolonged inward.
