882 VINE : POLYZOA AND MICROZOA OF YORKSHIRE AND NORFOLK. 
It is useless to give any synonyms of the above species in this 
case, as I am somewhat doubtful about the identity of this ill- 
preserved example, but I believe that I am right. 
§ B. Rectangulata, Waters. 
In wliicli the Zooecia or cancelli open for the most part at right 
angles to the axis or surface of the Zoariuin or sub-colony. 
Genus Ceriopora, Goldfuss. 
1826. Ceriopora (pars.) Goldf. : Petrifacta, &c. 
In establishing the genus Ceriopora, Goldfuss accepted for his 
type Alveolites, Lamarck : altogether Goldfuss described about 37 
species, but since his time the genus has been broken up consider- 
ably. d'Orbigny admits (Terr. Cret. v., p. 1030) the following 
Cretacous species : — 
1830. Ceriopora tubiporacea, Goldf., Petrifacta, pi. x., f. 13. 
„ „ milleporacea „ ,, pi. x., f. 10. 
,, ,, micropora ,, „ pi. x., f. 4. 
1845. Ceriopora truncata, Mich. Icou., pi. li., f. 7. 
34. Ceriopora micropora ? Goldf. (Vine), Quart. Journ. Geol. Soc, 
vol. xlvi., p. 480. 
Two examples of this species were found among the fossils 
submitted to me for examination. 
Habitat : Embedded in fragments of Red Chalk. 
Horizon : Middle Bed, Hunstanton.

1826. Ceriopora (pars.) Goldfuss ; Blainville. 
1852. Reptomulticava, d'Orb., Terr. Cret. v., p. 1032. 
35. Reptomulticava simplex, d'Orb., Terr. Cret. v., p. 1041, pi. 793, 
fig. 5. 
Habitat : On Terehratida hiplicata. 
36. Reptomulticava colhs, d'Orb., Terr. Cret. v., p. 1036, pi. 792, 
figs. 1, 3.
