POLYZOA. 139 



A somewhat larger and coarser type than that figured by. 

 d'Orbigny. 



Localities. Up ware, Farringdon. 



S. Europe. Le Havre, in the C^nomanien beds. ' 



Radiopora bulbosa, d'Orbigny, var. 



Radiopora bulhosa, d'Orb. Palaeont. Francais Terr. Cre't p. 99 6^ 

 pi. 650, f. 6—8. 



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), C^nomanien. 



Ceriopora (Echinocava) E-aulini, Michelin. 



Geriopora Raulini, Mich. 1841, Icon. Zooph. 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 calicos of a coral. 



Localities. Upware. 



S. Europe. Grandpr^, Ardennes. 



Ceriopora (Reptomulticava) mammilla, Reuss. 

 Reptomulticava mammilla, d'Orb. Pal. Fr. Terr. Gret. V. p. 1041, 



pi. 793, f. 3, 4. 



Localities. Brickhill, Farringdon.
