about eighteen months old; a splendid male ostrich, to 
mate the two females previously in the collection ; two Afri- 
can civets (Viverra civetta) ; two common genets {Genetta 
vulgaris), and an Egyptian ichneumon (Herpestes ichneumon). 
8. Three rare and interesting monkeys from South Amer- 
ica were procured on June 14th : — The Chuva spider mon- 
key {Ateles marginatus) ; the brown howler {Mijcetes fuscus) ; 
and the black saki {Pithecia satanas). Two very large pig- 
tailed macaques (M. nemestrinus) were received on the same 
date. 
9. A tortoise was presented on June 29th. The locality 
from Avhence it came was unknown, but it appears to be 
(Testudo tabulata), a Brazilian species. 
10. A brown-headed parrot {Poecephalus fuscicapillus), 
from Sierra Leone, was purchased July 8th. 
11. On July 11th, a fine specimen of the tw^o-toed sloth 
was received from Panama and has thriven remarkably 
well, in view of the difficulty commonly experienced in 
keeping these animals in captivity. It is thought to be 
(Cholopus hoffmanni), a different species from those previ- 
ously in the collection, — this can not, however, be fully de- 
termined until the death of the animal. 
12. Several specimens of the ruff {Machetes pug nax) and 
lapwing ( Vanellus cristatus), from Europe, were received on 
the 25th of July, and at the same time two pairs of Austra- 
lian and crowned cranes. 
13. On August 21st, two young female chimpanzees were 
purchased from a dealer in New York, and have proved 
exceedingly attractive to visitors, as was the case with those 
previously owned by the Society. The possession of these 
animals has afforded for comparison the interesting specta- 
cle of specimens of the two best known of the anthropoid 
apes, the chimpanzee and the orang, side by side in the 
same cage. Unfortunately, " Topsy," the female of the 
latter species, which had been in the Garden since October 
2d, 1879, died in January of the present year. 
14. Several specimens of a rather rare species of horned 
lizard (Phrynosoma douglassi) were brought from the Bad
