POLYZOA. 139 



A somewhat larger and coarser type than that figured by 

 d'Orbigny. 



Localities. Upware, Farringdon. 



S. Europe. Le Havre, in the Ce'nomanien beds. 



RADIOPORA BULBOSA, d'Orbigny, var. 



Radiopora bulbosa, d'Orb. Palaeont. Francais Terr. Cre't. p. 996, 

 pi. 650, f. 68. 



Our specimens are much larger than (four times as large as) 

 that figured by d'Orbigny, and the base is deeply concave, so that 

 the colony is a hollow hemisphere instead of a pyriform bulb, as 

 in d'Orbigny 's type. Without seeing more specimens I cannot 

 consider these differences as of more than varietal value, and 

 therefore name our specimens Radiopora bulbosa, var. magna 

 (Keeping). 



Localities. Upware. 



S. Europe. Le Mans (Sarthe), Ce'nomanien. 



CERIOPORA (ECHINOCAVA) RAULINI, Michelin. 



Ceriopora Raulini, Mich. 1841, Icon. Zoopli. p. 2, pi. 1, f. 7. 

 Echinocava Raulini, d'Orb. Pal. Fr. Terr. Gret. V. p. 1013, 

 pi. 788, f. 7, 8. 



A beautiful, coralloid, obtusely-spinose form of Ceriopora, not 

 uncommon at Upware. The echinoid processes seem to be com- 

 posed of less durable material than the main mass, so that in some 

 specimens they have been worn away into crater-like hollows, 

 very similar to the calices of a coral. 



Localities. Upware. 



8. Europe. Grandpre, Ardennes. 



CERIOPORA (REPTOMULTICAVA) MAMMILLA, Reuss. 



Reptomulticava mammilla, d'Orb. Pal. Fr. Terr. Cre't. V. p. 1041, 



pL793, f. 3, 4. 



Localities. Brickhill, Farringdon. 

 N. Europe. Bilin, Bohemia. 

 /S. Europe. Depts. Loire and Charente Infr. (Senonien).
