of the Angel-fish (Squatina alifera) ; Sea-scorpions (Slimonia 
and Stylonurus) ; and Sea-lilies (Pentacrinus), of which 
there are also two fine original specimens from Dorset and

A Case of Models of Foraminifera, prepared by Reuss 
and Fritsch, shows the wonderful variation in this group of 
microscopic fossils, and actual specimens are mounted along- 
side indicating their minute size. 
Ranged just above the floor angle is a series of large 
Cephalopod shells, comprising Ammonites such as Pachy- 
discus from the Lower Chalk, Parkinsonia from the Inferior 
Oolite, Aegoceras from the Lower Lias, as well as a Nautilus 
from the Oxford Clay. This series is supplemented by a 
Floor-case with Stephanoceras, Cyrtoceras, Agoniatites, 
Arietites, Sonninia, Aspidoceras, and Amaltheus, also 
large specimens of Lima, Pinna, Caprina, Pleurotomaria, 
and Natica, in illustration of the Phylum Mollusca. 
Two long Wall-cases are devoted to exhibits of Fossils 
generally too large to show in the Table-cases.
