up to four or five in number (c). In the very posteriorraost 

 part on both ventral and dorsal surfaces, the calcareous 

 bodies present striking features. Here among tables of the 

 ordinary sort are found very robust ones as large as 0.2 mm., 

 when measured from one end of a cross-arm to that of 

 the opposite arm. Together with these huge four- armed tables 

 there are, in a layer below them, large irregular calcareous 

 bodies which are fundamentally X- shaped and present all sorts 

 of irregularities (/, m). They are over 0.2 mm. in their longest
