 In fig. 6 (our fig. 30) we have a strongly aculeated, elongate- 

 oval segment, bearing four, short, divergent, lateral tubes, 

 and terminated at each end by a stolon-tube (broken). An 

 example of somewhat similar character is shown in fig. 9 

 (our fig. 31) ; but here the segment is triangulo-globose, 

 with three large stolon-tuhes proceeding from it, and with 

 a fourth, central, smaller tube at right angles to the others. 

 The surface in this specimen is sparsely, though strongly, 

 aculeate. The figs. 7 and 8 are elongate-pyriform segments 

 terminated by stolon-tubes more or less short. The re- 

 maining figs. 10 and 11 represent sections of the test, and 

 show; marked difi"erences in their thicknesses. The first two
