lated, cellular, and corticated Polypes. Of the room ix 
tubulated polypes (Case 26) the principal ge- Nat. Hist 
nera are Tubipora and Polystomus (formerly 
Tubip. serpens). — Among the cellular polypes 
(Cases 26, 27) are the genera Cellepora, toge¬ 
ther with Lunulites, Orbulites, &c.— The re¬ 
maining cases contain the various genera of that 
section of the corticated polypes which com¬ 
prises the Madrepores, such as Cyclolites, As- 
PIDISCUS, TuRBINOLIA, FuNGIA, CARYOPHYLLiEA, 
Madrepora, Astr^a, Hydnophora, with some 
other undescribed genera. 
In Cases 30 to 37 a considerable suite of 
fossils, mostly belonging to the Alcyonia and 
Sponges. 
Cases 38 and 39 are chiefly occupied by fos-^^ 
sii remains of the class Crustacea, divided into 
various genera, and including the order of Tri- 
lobites of which the principal genus is that of 
Calymmene, familiarly known by the appellation 
of the Dudley Fossil; with the related genera 
Belonurus and Limulus. To these are added 
(in Case 39) remains of insects (chiefly of the 
order of Neuroptera) from the marl slate quarries 
of Oeningen, &c. 
Cases 42 and 43 (near the window) contain, ' 
among other interesting vegetable remains, an 
extensive collection of fruits and seeds from 
the blue clay of the cliffs in the Isle of Sheppey, 
and impressions of leaves and other parts of 
plants, in bituminous marl slate from Oeningen, 
&c. TENTH
