proved to be the hair-crested or Javan species (Leptoptilus 
javanica). 
31. A black-billed tree duck {Dendrocygna arbor ea), from 
the Caicos Islands — part of the Bahama group — was re- 
ceived in the same month. 
32. The white-collared mangabey {Cercocehus coUaria), 
added in September, belongs to a species rarely seen among 
monkeys kept in captivity. 
33. A pair of prong-horned antelopes {Antilocapra ameri- 
cana) were procured from Nebraska during the early fall, 
and have, so far, done better than any previously ow^ned by 
the Society. The want of adaptability to changed condi- 
tions of life is strongly marked in this animal, as in all the 
herbivora, whose original range w^as west of the Mississippi 
River, and another attempt to domesticate it here is of spe- 
cial interest. 
34. On the 30tli of September a young male Burchell's 
zebra {Equus hurchelli), purchased in Europe for the So- 
ciety, arrived at the Garden. 
35. A great white-crested cockatoo ( Cacatua cristata), pre- 
sented in October, is the first of the species in the collec- 
tion. 
36. A fine pair of African porcupines (Hystrix cristata) 
were purchased in the same month. The male is remark- 
able for his large size. 
37. One of our native birds, rarely captured and domesti- 
cated with success, was also presented — the golden-crowned 
kinglet {Regulus satrapa). 
38. A black scoter duck {(Edemia americana), from the 
north Atlantic coast, was new to the collection. 
39' A pair of St. Thomas conures {Conurus xantholsemus), 
from the island of that name, were procured by purchase. 
40. A bird sent to the Garden in November, without any- 
thing to indicate its native region, has been identified as 
the sulphury tyran ( Tyrannus sulphureus) of South America, 
one of the large and varied group of flycatchers. 
41. One of the familiar birds of Europe, the cole titmouse 
{Parus ater)j was received by presentation.
