190 MR JAMES MURRAY ON 
EXPLANATION OF PLATES. 
The figures are all drawn by me from living animals, except that of Notommata pumila, which is 
drawn by Mr F. R. Drxox-Nurratt from a specimen mounted by Mr Roussrner, and the jaws of the same 
species, which are copied from a sketch by Mr Roussrter. The drawings of the whole animals are as far as 
possible drawn to the same scale, so that some idea of comparative size may be got. 
was so large that it had to be drawn on a reduced scale.
