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. Dixox-Nuttall from a specimen mounted by Mr Rousselet, and the jaws of the same 

 species, which are copied from a sketch by Mr Rousselet. 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. Pseudo&cistes rotifer 

 was so lame that it had to be drawn on a reduced scale.
