GALLERY. 
(Stair from Vestibule.) 
The collection of Local Marine Invertebrates, which 
occupies the greater part of the wall cases round the 
gallery, is largely the result of the work of the Liverpool 
Marine Biology Committee. The series commences to 
the left of the door with the Sponges, and continues round 
the cases labelled Coelenterata, Echinodermata, Polyzoa, 
Vermes, Crustacea, Mollusca, and Tunicata. 
In the windows of the gallery are arranged a series of 
lantern slides, prepared by the Rev. T. 8. Lea, from his 
photographs of the sea-weeds and animals on the shore 
round the south coast of the Isle of Man. 
- In some of the desk cases round the rail of the gallery 
will be found a collection of Sea-bottoms, ancient and 
modern, both from shallow and deep water. These 
include a series of the gravels, sands, muds, and organic 
deposits found in the various parts of our own district. 
Two of the desk cases, on the north side, show an 
interesting series of the Microscopic Copepoda, and 
enlarged representations of their structure, prepared by 
I. C. Thompson, Esq.
