the neighbour of Trochoseris ia the subfamily of the Lophoserince. This last 

 genus has a columella, and the new one has none. 



The species has not been hitherto described, but it has been familiarly- 

 known as a MontUvaltia ; but the synapticulae between the septa and costoe 

 determine the form to belong to the Fungidce.
