106 QUEENSLAND ETHNOLOGICAL NOTES, 
It was known by the native name of “‘ Decrannie,”’ 
and the keen edge of the lancet made the latter particularly 
suitable for scarifications (tribal marks, etc.) 
The specially-flaked piece of bottle glass is not too 
securely attached to a flat piece of wood by means of gum 
‘(not gum cement). The blade when not in use is protected 
by being inserted into a groove at the upper end of a piece 
of rounded hardwood as seen in the illustration. (PI. IV., 
fig. 3). The two pieces are then tied together with some 
grass or vegetable fibre to keep them intact, and when thus 
placed the scarifying portion of the implement is in an 
unsymmetrical position, due to inaccuracy in the making. 
Measurements are as follows :— 
Length of knife, 73mm. 
Length of blade of knife, 25mm. 
Width of handle of knife, 11mm. 
Length of protecting case, 120 mm. 
Width of protecting case, 15mm. 
and the greatest width of the groove is 5mm, narrowing 
down tcwards the centre of the wood to suit the shape 
and angle of the blade. 
Lord Avebury, in “ Prehistoric Times” (1900), (p. 422) 
refers to and figures (fig. 220) a knife similarly mounted 
but consisting of splinters of quartz (or flint) arranged in 
a row after the manner of the Queensland ‘“ Shark-Tooth 
Knife,’’ but possessing no protective portion as in specimen 
above described. This instance is also interesting evidence 
that there was no persistency of type amongst Australian 
hafted cutting implements.
