(The last four specimens are imperfect, the bases having been 

 broken off.) 



From this tabulation it will be seen that in this species lateral 

 growth ceases after a maximum diameter of 0-10 by 10-11 mm has 

 been reached, although the height may extend to as much as 39 mm. 

 (Those specimens having diameters greater than the maxima re- 

 corded have been laterally compressed and distorted.)
