evert this through the mouth, they are able to surround 
and feed upon objefts otherwise too large to be swal- 
lowed. The larval stages are free-swimming and of 
very variable shape. Owing to the presence of a hard 
spiny shell, the group name Echinodermata is applied 
to the class. Many of the forms are found as fossils in 
very old geological strata, and some of them, such as 
the common so-called " sea-lilies", are still found living, in 
enormous abundance, in certain regions of the deep-sea. 
In the corner, overhead, are seen some horns and a 
skull of the common buffalo (Bubalus) of the East Indies, 
These horns are very large and are quite different from the 
short horns of the Bison, a related form commonly known 
as the buffalo, but quite different from it, and confined to 
the prairies of North America. To the left of these are 
shown some large specimens of stuffed rays. 
The large case of native Indian objefts, is well worthy 
of special examination. In the front, above, hangs a line 
of aprons — an apron or "queyu" forms a complete dress for 
an Indian woman. Behind and below hang hammocks of 
various sizes and patterns, one of Brazilian origin, 
made by Indians on the Rio Negro, and ornamented 
with feathers in a most beautiful manner. In the centre 
and at the sides are shewn feather dresses for the head 
and shoulder. The central figure — a wax model from 
London — represents an Indian child in its hammock; 
and on each side of this are grouped necklaces chiefly 
made of the canine teeth of the bush-hog ; armlets of 
different sorts ; flutes made of bones ; and stringed seeds 
which, tied to a stick and shaken in the dance, pro- 
duce an effe6live noise. Behind is a large Warrau 
wrestling shield ; on each side of this hangs a quiver of
