 ging from the outer surface. Ovisacs ovoid, membranaceous ; outer 

 surface covered with dispersed and subfasciculate fusiform spicula.

Nardo has a section of calcareous sponges ; but it must not be con- 

 founded with this group. It is founded to contain two corals, allied 

 to Alcyonium and Gorgonia, having no alliance with sponges. 



Nardo gave the name of Grantia to a dendroid genus of fibrous 

 sponges, of which Spongia canabrina of Esper is the type (see Isis, 

 1833, p. 522).
