NOTE. -As it was necessary to assign numbers to these figures before they could be 

 assembled on the plate, the sequence of the numbers has been broken up. 



As the figures are of different degrees of magnification, the longest dimension of the 

 specimen viewed as in the figure follows the name in the references to this and the 

 other plates, except where otherwise stated.
