There are a number of species, of which the best known are 
the Red and Blue Macaw {Ara macao), the Red and Yel- 
low Macaw (Ara chlo ropier a), and the Blue and Yellow 
Macaw {Ara ararauna). 
Nos. 8 and g. — THE LARGE SEAL 
PONDS. 
The upper one of the three large ponds is at present unoc- 
cupied, it being the desire of the Society to fill it with a col- 
ony of otter, which, owing to the difficulty of procuring them 
uninjured, it has not yet been possible to obtain. 
The central and lower ponds are tenanted by a number of 
Gillespie’s YLmv. 'S>Y.KLS>{Z alophus gillespii). This species is 
found in large numbers in the lower part of the North Pacific 
Ocean ; those which are in the Garden having been captured 
at the San Miguel Islands, off the coast of California, not far 
from Santa Barbara ; they are rarely seen as far up as San 
Francisco, and are found in the waters of the same latitude 
on the Asiatic side of the Pacific. 
The differences between this species and the Northern Sea 
Lion {Eumetopias stelleri), numbers of which afford great 
amusement to visitors to Seal Rock, in the bay of San Fran- 
cisco, are mainly in size, the males of the latter growing much 
larger, and also in the development of the skull and teeth. 
The male Hair Seal, when adult, weighs three or four times 
as much as the female, and is provided with enormous canine 
teeth, with which they fight terrible battles at the season of 
Tutting, often injuring each other severely ; they are of a sav- 
age and dangerous disposition and are ugly antagonists even 
to man. On the expedition which captured those now in the 
Garden, one of the men was seized and so bitten and torn by 
a large bull Sea Lion that he died from the effects of his 
wounds. 
They swim and float with great address, sleeping on the 
isurface of the water ; they remain at sea during eight or nine 
months of the year, coming out on shore in vast numbers at 
Ithe season of breeding, where they remain in some cases as 
much as three months without food or water. On land they 
iprogress with more ease than is common with other seals, by
