 nearly three times as broad at the base as long ; sides con- 

 verging from base to apex, the anterior angles produced, their 

 apices obtuse. Elytra broader than the thorax, dilated pos- 

 teriorly, very convex, not depressed below the basilar space,

Sponge simple, more rarely compound. Individual persons 

 clavate, cylindrical, top-shaped or pyriform, thick-walled. 

 Vertex truncate or convex. Stomachal cavity funnel-shaped, 

 more or less impressed, rarely reaching to the base, usually 

 divided at its lower end into a bundle of vertical tubes. Os- 

 culum of the central cavity often radiated by open radial 

 furrows. Into the stomachal cavity open radial canals, usually 

 curved outwards and downwards, which gradually become 

 finer as they depart from the stomachal cavity. Surface fur- 

 nished with the ostia of fine incurrent canals, which usually 

 open obliquely inwards and downwards, and run into the 

 radial canals of the stomachal cavity. Base sometimes with 

 a dense dermal layer.
