arranged something like those of a saw on each side (fig. 9). 
Of this form, a remarkably large specimen from the coast of 
British Guiana (Pristis perrotteti) is exliibited. Another very 
small division of fishes comprises the Lampreys and Hags, ot 
which a few specimens are shown in case 44. 
The largest specimen of the class, 
placed near the centre of the room, sus- 
pended from the roof, is a full-grown 
example of the Great Basking Shark 
(fSelache maxima), fig. 10, which was 
captured on the 2nd of March, 1875, 
near Shanklin, in the Isle of Wight. 
Its length is twenty-eight feet, but, as 
the minute size of the teeth indicate, 
it is a comparatively harmless animal. 
Beyond is a young specimen of a shark 
(Bhinodon typicus) which when adult 
is said to attain a still larger size. It 
inhabits the Indian and Pacific Oceans. 
In the middle of the north end of the 
Fish Gallery a large table-case is placed 
containing a selection of the most im- 
portant forms of Amphibians, which 
are divided into such as possess a tail 
— Salamanders and ISTewts, and into 
those without tails — Frogs and Toads. 
These animals live during some period 
of their existence in the water, when 
they breathe by gills, and are there- 
fore very closely allied to fishes. The 
comparatively enormous size attained 
by certain tropical species of Frogs 
and Toads (fig. 11) should be noticed, 
tion of the group is the Giant Salamander of Japan. 
II. A small gallery is devoted to the group of Articulata 
or Invertebrated animals with jointed limbs, as Insects, Spiders, 
Myriopods, and Crustacea. In the wall-cases are many curious 
examples of nests, and of specimens illustrating the ravages of 
destructive insects, and also some of their economic products.
