III. A DESCRIPTION OF THE GENERA SYRINGOSPHMRIA AND STOLICZKARIA OF THE ORDER 



SYRINGOSPH&RID&. 



Order : SYRINGOSPH^ERID^G. 



Body free, spherical or spheroidal in shape, consisting of . numbers of limited, more or 

 less conical, radiating congeries of minute, continuous, long, bifurcating and inosculating 

 tubes ; also of an interradial close or open tube reticulation arising from and surround in u,- 

 the radial congeries. Tubes opening at the surface on eminences and in pores, and ramify- 

 ing over it. Tubes minute, consisting of a wall of granular and granulospiculate carbonate 

 of lime. Crenenchyma absent. 



The presence of pores on the surface of some forms of the order, and their absence in 

 others, and the very close nature of the interradial reticulation in the poreless kinds, necessi- 

 tates its division into two genera. 



Genus: SYRINGOSPHJERIA. 



Body large, symmetrical, nearly spherical or oblately spheroidal, covered with large com- 

 pound wart-like prominences with intermediate verrucosities, or with compound monticules 

 having rounded summits, with solitary eminences between them, or with close broadly round- 

 ed tubercles, or with minute granulations. Rounded, or oblique, or linear depressions occur 

 on the surface usually between the eminences, but sometimes upon them ; they are shallow 

 and are bounded by tubes, some of which open on their floor. The surface has tubes opening 

 on it from the internal radial series, and also from the interradial tube reticulation ; also
