98 SPOLIA ZEYLANICA., 
pebbles by a smart blow delivered with a hammer-stone. The 
result of such a blow, of course, was to cleave from the pebble 
a segment having an oval outline, one flat, and one domed 
face. Such segments were, no doubt, used as knives, while 
trimming of the edge produced a scraper ; these I call split 
pebbles, and since all these tools, whether of the chipped or 
split variety, are restricted in form by the stones from which 
they were made, I class them all together as the ‘‘ Pebble 
group.” There is another class of pebble tools which I regard 
as probably of later date. : 
These are widely distributed, but few and far between. 
They are small oval pebbles of crystal quartz, seldom more 
than an inch in length, which have been worked in such a 
manner that they resemble very tiny hand-axes of the Chellean 
period of Europe. They are delightful little tools, but I cannot 
tell what they were used for ; and, as far as I know, they do 
not occur outside Ceylon. 
The remaining artefacts are mostly unconditioned by the 
pebble outline. In passing we may note that pebbles of chert 
are by no means common, although this substance was 
extensively used by prehistoric man. Of angular fragments 
there is any number. 
The Chellean phase seems to be represented by the usual 
hand-axe ; but I have found few of these. The best example 
that I have came from the elevated ground to the east of 
Pomparippu ; and one I found in situ at the base of the red 
earth near Marichchukkaddi. Serapers of all sorts (hollow, 
round, straight, and irregular) are common. Side scrapers, 
the racloir and “‘ pointe,’ of Mousterian type occur, as do 
tea-cosy and prismatic tools. Pointed instruments with edge 
trimming, resembling that of the Aurignacian culture, and 
‘* hoof-shaped ”’ pieces recalling those of Egypt* and North- 
fleet in England, are characteristic. Steep-faced scrapers or 
planes are very common, and Dolphin planes are to be found, 
columnar cores, conical cores, and throwing discs are fairly 
abundant. “* Dosquabattu ” knives and forms that I class as 
** neelers ’ arecommon. Beaked instruments are to be found.
