The number of English Fossil Species must at present be received as an 

 approximation. 



The foregoing table contains 158 species, out of which 

 number naturalists have been able to identify 1 6 species only, 

 as agreeing with any now known, that is to say, occurring 

 both in a recent and fossil state ; 30 species were found in a 

 recent state only ; 1 2 species are not distinguished in the list, 

 as to which class they belong ; and the remaining 100 species 

 are exclusively found in a fossil state. Sixty-five species are 

 distributed in the English formations, and are almost en- 

 tirely derived from the last-mentioned class. 



Recent analogues of several of the fossil echinites exist in 

 the South Seas. The British seas produce 7 recent species, 

 according to Dr. Fleming.
