from the jaw ; tlie serrated edge, in some specimens, is beau- 

 tifully perfect, and many of them are nearly equal in size to 

 the largest of those from Tilgate Forest. Good specimens, 

 certainly, are not common. At the same time I obtained 

 from the quarrymen, and by my own exertions, a series in 

 every stage from the perfect tooth to the worn-out stump. 



III. — Megalosaurus. The teeth of this animal found at St. 

 Leonard's and Battle, cannot by any means vie in magnitude 

 with those from Stonesfield : in general they are only about 

 half the size, and some of them are still smaller. There is a 

 variety occasionally met with, which is shorter, more curved, 

 and rather thicker in proportion than those of the usual form; 

 it might be a subject of enquiry whether this belongs to a dis- 

 tinct species, or be only from a different part of the same ani- 

 mal. At St. Leonard's it is of rare occurrence to meet with 

 even a fragment of the tooth of a Megalosaurus ; but at the 

 small quarry near Battle, before alluded to, they are occasion- 

 ally found, though not in any great abundance. 



IV. — Phytosaurus cylindricodon. The teeth which are fi- 

 gured by Dr. Mantell, as belonging to this animal, appear to 

 be extremely rare throughout the wealden : I met with only 

 one at St. Leonard's during the last winter, and from the Bat- 

 tle quarry, four or five perfect and imperfect specimens were 

 all that could be obtained. They appear to differ slightly 

 from those figured by Dr. Mantell ; the upper part is rather 

 more flattened, and bent inwards, and the whole surface is 

 deeply and irregularly wrinkled. All the specimens, like those 

 from Tilgate Forest, appear to have been broken short off.

Art. VII. — Remarks on the Skeletons of the common tame Goosey 

 the Chinese Goose » and the Hybrid between the two. By T. C. 

 Eyton, Esq., FX.S. 



The circumstance of hybrids produced between the tame 

 goose and the Chinese goose being again productive, was the 

 inducement which led me to make the following examination 

 of their respective skeletons, in order to ascertain the degree 

 of similarity existing between them. Before however stating 

 the results, it may perhaps be as well to mention the mode I 

 followed in order render the hybrids productive, which was 

 simply the placing together a male and female, of different 

 hatches ; though the birds were both young, they reared eight 

 young ones.
