the Caspian tern, roseate tern, gull-billed tern, minute tern, &c., of 
Britain ; white-winged tern, &c. The Skimmers have remarkably 
formed bills, that enable them to skim the surface of the sea, in which 
they dip the lower mandible, the upper being elevated out of the water, 
until the prey is felt by the lower ; as in the black skimmer. 
Case 16*2. The Tropic Birds are peculiar to tropical climates, 
where they catch the flying-fish, &c., as the common tropic bird, red-tailed 
tropic bird, &c. The Darters live in small flocks, on the trees that 
overhang the rivers, &c., from whence they plunge into the water, and 
catch fish by darting at them with their sharp bill and long vibrating 
neck ; as the white-bellied darter, &c. 
Cases 162— 166. The Pelicans that inhabit the marshes and sea 
coasts, feeding on fish, &c. ; as the gannet, of Britain, &c. Cases 163 
and 164. White pelican, red-backed pelican, &c. Case 165. Common 
cormorant, shag of Britain, Sec. ; and Case 166. Greater frigate bird, 
and lesser frigate bird. 
The Eggs of Birds 
are placed in the smaller Table Cases along the side of the room ; 
they are arranged in the same series as the birds in the Upright Cases. 
The Table Cases, in each department of the room, contain the eggs of 
the species in the Cases near to them. 
The Shells of Molluscous Animals 
are placed in the larger Table Cases across the sides of the room, 
(in progress of arrangement). 
Tables 1 — 26. Univalve Shells, 
belonging to belly- walking, or Gasteropodous Mollusca. 
Tables 1, 2. The Strombs, as the large pink-mouthed stromb, 
from the West Indies. With it are some of the pink pearls which 
are formed by the animal ; they are extremely rare and valuable when 
of a good shape. The Diana ear stromb ; the spiders’ claws, sea 
scorpions, &c., which are peculiar for the outer lip of the full grown 
shell being furnished with finger-like projections ; the terebellum, which 
is polished like the olive, but has no groove on the suture, and the 
front of the shell as it were cut off. The spindle strombs, of the Red 
Sea, which have the cavity of the tip of the shells filled up with 
crystalline matter as the animal grows. 
Tables 2—8. The various genera allied to Murices. 
Tables 2, 3. The Trumpet Shells ( Triton ), the larger species of 
which is often used as a trumpet by the natives of the Pacific Islands. 
The angulated or gadrooned triton. The gadrooned edge, so generally 
used by silversmiths, was taken from the finely wrought margin on 
the mouth of this shell. The frog shell ( JRanella ), so called because 
they are flattened shells, and have a ridge of spines on each side. 
Tables 3, 4. The Rock Shells ( Murex ), so beautifully ornamented 
with the foliaceous, curled, and spinous protuberances with which their 
shells are adorned. Among others, the Murex trunculus of the Medi- 
terranean, which is believed to have yielded the Tyrian purple of 
the ancients. The Slit-mouthed Shell ( Pleurotoma ), with a notch
