 Romingeria, Nicholson, 1879, Tab. Corals, 

 p. 114. [Ety. proper name.] Coral- 

 lum lax, spreading; corallites cylin- 

 drical, annulated, multiplying by 

 lateral gemmation, and typically pro- 

 ducing new tubes, in umbellate whorls 

 or verticils, at short intervals ; where 

 the walls are in contact with the 

 visceral chambers they are connected 

 by mural pores; tabulae complete, re- 

 mote; septa represented by vertical 

 rows of spinules. It resembles Aulo- 

 pora, but is only attached basally, and 

 is therefore free throughout the greater 

 part of its extent. Type R. umbel- 

 lifera.

 in the type, have constricted corallites 

 and minute mural pores. Type S. ovata.
