characters in Lamouroux's table of 51 recent species, the 

 result is rather an approximation to similarity, in a few cases, 

 than an identification with any existing kinds. The recent 

 v41cy6nia are disthiguished from the Sponges by having an 

 external skin, full of openings, possessed by oviparous tenta- 

 culated hydrae. 



Under the subdivisions, polypifers formed like network, 

 foraminated polypifers, lamellated polypifers, cortiferous poly- 

 pifers, &c., numerous genera have been described by Ellis 

 and by Lamarck, and many fossil kinds are known in the 

 English formations. They are extensively distributed, and 

 abound particularly in the mountain limestone, the coral rag, 

 and the crag. (fig. 58.) 



We have introduced into the following table some of the principal genera 

 of fossil corals, &c. : — 



«, Flustra, Suffolk, Crag, 



5, E'schara, Aldburgh, Crag. 



c, Retipora, Sunderland, Magnesian 



limestone, 

 (f, Cellepora, Dudley, Moun. limest. 

 €y Catinipora or Tubipora, Chain 



coral. Mountain limestone. 

 fy Caryophyllae a, Norwich, Chalk. 



gy Caryophyllae^a, Steeple Ashton, 

 Coral rag. 



hy Stylina of Parkinson, Cumber- 

 land, Mountain lime&tone. 



iy Astrea, Mitford, Bath oolite. 



ky Madrepora, Dudley limestone. 

 The Stylina above given is by some 



called a ramose Caryophyllae^a. 



In the transition limestone, several fossil species are 

 arranged under the genus Stylhia. " The recent species, 

 which Lamarck considers as the type of this genus, was 

 brought from the South Seas, and furnishes us with another 

 instance of animals whose remains are found in formations of 

 the earliest creation ; no traces of which animals have been 

 seen in any of the subsequent formations, but are now found in 

 a living state in the seas of the opposite hemisphere." {fg. 59.)
