amygdalus (Almond Urchin).— Case 21 those 
of Echinospatagus (Spatangus Urchin). 
Cases 22 and 23 contain the various genera of 
the zoophytes commonly called Encrinites, &c. 
In Cases 24 to 29 are deposited the tubulated 
cellular, and corticated Polypes. Of the tubulated 
polypes (Case 26) the principal genera are Tu- 
bipora and Polystomus (formerly Tubip. ser¬ 
pens ).—Among the cellular (Cases 26, 27) are 
the genera Cellepora, together with Lunuli- 
tes, Orbulites, &c. —The remaining cases con¬ 
tain the various genera of that section of the 
corticated polypes which comprises the Madre¬ 
pores, such as Cyclolites, Aspidiscus, Turbi- 
nolia, Fungia, Caryophylljea, Madrepora, 
AsTRiEA, Hydnophora, with some other unde¬ 
scribed genera. 
In Cases 30 to 37 a considerable suite of 
fossils, which have been considered as belonging 
to the Alcyonia and Sponges. 
Cases 38 and 39 are chiefly occupied by fossil 
remains of the class Crustacea, divided into 
various genera, and excluding the order of Tri- 
lobtes of which the principal genus (Calymene) 
is familiarly known by the appellation of the 
Dudley Fossil. To these are added (in Case 39) 
remains of insects (chiefly of the order of Neu- 
roptera) from the marl slate quarries of Oeningen, 
&c.
