Neosiphonia n. g. Sollas (1) Tetracladidae with a more or less ovate body 

 supported on a longer or shorter stem; canal-system as in the fossil genus 

 Siphonia. The ectosomal megascleres are dicho- or trichotriaenes. The 

 microsclere is a spirater (?). 



— superstes n. sp. Sollas (1) Matuka, Fiji Ins. 315 Fad. 



— schmidtii n. sp. Sollas (1) Golf von Mexiko. 



Pleroma n. g. Sollas (1) Pleromidae in which the flagellated Chambers are 

 large, with wide short aphodi. The microscleres are microxeas and spirasters.

 Sympyla n. g. Sollas (1) Azoricidae in which the poral terminations of the 



excurrent canals are collected into separate areas, which are distributed 

 over one side of the sponge; the oscules are simple, and are distributed 

 over the side opposite to that bearing the pores. 

 Tretolophus n. g. Sollas (1) Azoricidae in which the oscules are arranged in 

 a linear series along the summit of a ridge-like elevation. Main excurrent 

 canals more or less vertical.
