The foregoing table contains 158 species, out of which 
number naturalists have been able to identify 16 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; 12 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.
