DISCOVERY REPORTS 



There are five specimens of roughly the same age as those described as numbers 3 

 to 9 above, though for the most part they are shghtly larger. They do not call for 

 individual description. The terminal plate appears to be single in all, though it is difficult

to be certain that it is. The longest columnals of the stem of one or two are longer

 contact with one another in all. In none of the specimens does the anal tube show 

 behind the radianal plate as in number 9.
