occiput, agreeing in this character with a series of Orang-Laut skulls from the 

 State of Trang, on the west coast of the Malay Peninsula, which the author has 

 recently described ^ in brief. An interesting feature of the series at present under 

 discussion, and also, so far as can be seen, of the Orang-Laut specimens, is the 

 large proportion of individuals in which the third molar has not developed 

 normally. Though the Malay and Siamese skulls in our collection show certain 

 resemblances to those representing the jungle tribes of the Malay Peninsula they 

 are separated from them by having a much higher cephalic index and a greater 

 cubic capacity, and by other differences of racial importance.

1, Palceolithic Im])lements from the Shelly Gravel Pit at Swanscomhe, Kent. 



By Mrs. C. Stopes. 



The late Mr. Stopes on April 27, 1900, discovered in a newly opened section of 

 sand and gravel in a pit at Swanscomhe, Kent, many remains of animal mollusca 

 and other fossils interstratified with flint implements of various kinds. The latter 

 included the following varieties : (1) Ordinary axe or hache type ; (2) fine smaller 

 of same shape ; (3) broad leaf-shaped type ; (4) ovate types ; (5) boat-shaped type| 

 pointed at each end ; (6) discs ; (7) large many-angled projectiles ; (8) very fine- 

 pointed stones as awls ; (9) worked as if for graving tools ; (10) worked as if to 

 clear marrow-bones ; (11) scrapers, spokeshaves, and combined stones in all colours 

 and shades of flint and patina — white cream, ochreous, brown, black. Many of 

 them are derived and waterworn, many are glaciated. 



As these are associated with a fauna containing many extinct species 

 Mr. Stopes considered that his discovery pushed back the geological date of man's 

 appearance in the lower Thames valley to a period much earlier than has hitherto 

 been supposed. The pit is now entirely worked out, and the specimens already in 

 hand alone remain to show its contents. 



The fossils have been verified by Mr. Kennard and are here given. Those
