 Leucoella, Gray. 

 Leucoella cervicornis, Gray, has been found at Port Denison, Queensland.

Suberia clavaria, Std., was taken in the Atlantic, off Monte Video, while Suberia 

 l-6llikeri, Std., occurred to the north of New Zealand, and Suberia genthi at Port Jackson.

The only species, Anthothela grandijlora (Sars.), originally described from Norway,
