62 SPOLIA ZEYLANICA. 
(4) RHOMBOIDAL appear to be lunates with the curved 
back truncated. I possess only three: two from Bandarawela, 
one from Dolosbage. 
(5) ANGULAR are often equilateral, but are sometimes 
constituted by a straight sharp edge and two curves meeting 
at a point. The scalene form, which is so common in Europe, 
appears to be entirely wanting in Ceylon. 
(6) D-sHAPED vary in length from seven-eighths to little 
more than a quarter of an inch. They are akin to semi- 
lunate, but are broad and squat and solid. They often 
contain the bulb. 
(7) BraKkep are of two types: the one for upward move- 
ments, the other for downward. In some cases the butt 
appears to have been trimmed for hafting. 
(8) Curvep Pornts, the most numerous of all types, vary 
in length from three-quarters to five-sixteenths of an inch. 
They are generally solid and are fashioned with exquisite 
skill. The butt is generally neglected. 
(9) Srraicur Points seem to be a variety of the preceding. 
(10) Dritt Points (figures 890, 891, 892, 893, 900, 901, 
1503) ; Professor Henry Balfour, of the Pitt Rivers Museum, 
Oxford, has suggested to me the identification of these 
implements. They are straight and roughly rectangular in 
section. None were brought to light in 1914. The first six 
were found in 1913, four below and two on the surface ; the 
seventh was found on the surface at Hatton. 
(11) Borers are generally triangular and thin. The work 
in which they were employed must have been very delicate. 
Almost every one which I possess would infallibly splinter if 
applied to wood or bone. 
(12) ARROWHEADS are generally of irregular lozenge shape 
with truncated base. They vary in length between eleven- 
sixteenths and three-eighths of an inch. Their diminution 
in breadth towards the butt does not amount to notching, 
but was intended no doubt to facilitate their insertion in. 
the shaft. No. 1,386 is so far unique in Ceylon, displaying 
one well-developed barb, but no stem. 
(13) BuapEs are flakes of crystal blunted by characteristic 
chipping along the back and with untrimmed convex edge.
