Reptonodicava „ d’Orbigny, 1854. Bry. Cret. p. 1015. 
Char. — Zoarium a piriform nodule, rising from a concave lower surface ; 
surface mammillated. 
Distrib. — Senonian — Maastrichtiau : Maastricht (/if^ Winkler) ; Gace, Central 
France {fde d’Archiac). 
Oberkreidemergel : Goslar, Germany {fde Homer ; the 
type locality). 
Cenomanian : Le Mans. 
Aff. — That this species is a Reptomulticava is most probable from the figure 
given by Michelin. Perhaps G. phymatodes, von Reuss, should be included as 
a synonym (p. 138). 
11. nodosa (Keeping), 1883. 
Syn. Ceriopora [Reptonodicava) nodosa, Keeping, 1883. Foss. Neoc. Upware, 
p. 140, pi. vii. fig. 14. 
Char. — Zoarium large, massive, concave. The upper surface is covered with 
prominent, well-raised mammillae. The specimens, according to Keeping, are 
as much as 4 x 4 x 8J inches in size. 
Distrib. — Lower Greensand : Brickhill, Upware. 
Aff. — Nearly allied to R. mamillosa, from which it differs by its larger size, 
larger zooecia, and more prominent mamelons. Keeping describes it as 
having a lamellar structure, so it must be excluded from Ceriopora.
