superposed lamellae. Each lamella is supported on the fascicles of the 

 inferior lamella, serving as pillars; it is formed of distinct subcolonies 

 in the form of Actinopora or of Lophole'pis, intimately joined 

 together. Each of the subcolonies has a distinct origin and arises 

 from a tube of a fascicle of the inferior lamella. 



The section figured by D'Orbigny is incomplete, for it does not 

 cut the basal portion of a subcolony and therefore does not show 

 exactly the formation of the zoarium. A section properly made shows 

 that the tubes are cylindrical, with 

 dorsal gemmation, vertically elevated. 



The fascicles are irregular, ovoid, 

 rather short, irregularly multiserial. 

 The specimen which we figure shows 

 at the right a subcolony in the form 

 of Actinopora and at the left a sub- 

 colony in the form of LopTiolepis. 

 The spaces between the fascicles are 

 smooth. We have not been able to 

 discover the ovicell.

 Switzerland .

MULTIGALEA, new genus 



The ovicell is elongate, star-shaped, with many branches; the 

 branches are separated by uni- or biserial groups of zooecia. The 

 tubes have an exterior, triangular, very fragile visor ( = galea) . The 

 tubes are cylindrical, with dorsal gemmation, elevated in their su- 

 perior half. The zoarium is composed of orbicular subcolonies irreg- 

 ularly superposed. The cancelli are small and denticulated in the 

 interior. 



Genotype. — Multigalea (Reptomulticava) canui Gregory, 1909. This 

 new genus differs from T^ftf^-iopora D'Orbigny, 1849, in the presence of 

 ovicells and in the occurrences of visors on the tubes.
