From reasons discussed in the paper read before the 
Greologists’ Association, it is recommended that three of the 
species of Ternnechinus founded by Professor Forbes should be 
merged; this receives the earlier name of L. Agassiz.

Diagnosis :—An Echinus of medium size, circular, depressed, 
but with a tendency towards a conical shape. 
Apical system fairly large. 
Ambulacra :—The pores are in very oblique arcs, so that the 
poriferous zones are wide. There is a row of large tubercles 
down each side of the area and a few scattered granules 
between. An alternation of wide plates hearing large tubercles 
with narrow plates ornamented only by granules occurs. 
Tnteradii : —A large tubercle occurs on each side of each area 
throughout the whole series. Except at the very summit, each 
plate has a second tubercle almost equal in size, so that the 
area appears packed by four rows of large tubercles. There 
are but few granules.
