30. Two specimens of the Arizona diamond rattlesnake 
{Crotalus adamanteus atrox) were received on the 9th of Oc- 
tober, from the neighborhood of Tucson. It is not probable 
that this species has ever before been exhibited in a living 
state outside of its native region. 
31. On the 11th of October two giant salamanders {Sie- 
holdia maxima), from Japan, were purchased, and are the 
most noteworthy additions ever made to the department of 
amphibia. It is the largest known member of the class, 
reaching a length of four feet ; one of those in the Garden 
appears to be nearly full grown, while the other is somewhat 
smaller. They have been exhibited in a number of foreign 
collections but with one exception, these are probably all 
that have, up to the present time, been introduced into this 
country. 
32. The genus Morelia represents the Fythonidse in Aus- 
tralia, one member of which, the beautiful carpet snake 
{M. spilotes), was received on the 16th. 
33. A small collection of snakes received in October from 
Georgiana, Florida, was found to contain some species of 
extraordinary rarity. Among them were the cyclops water 
snake {Tropidonotus cydopeum), the fiat- tailed water snake 
{T. compressicaudus), and Sacken's garter- snake (Eutsenia 
sackeni). 
34. A specimen of the blue-rumped parrakeet {Psittinns 
malaccensis), from Malacca, was purchased on the 29th of 
November and added to the fine collection of Psittacidss, 
which, at present, fully occupies the cages on the east side of 
the aviary, and is becoming uncomfortably crowded. 
35. A monkey presented on the 17tli of December, by 
Dr. G. G. Green, of Woodbury, N. J., proved to be the white- 
cheeked cebus {Cebus kmatus), of Brazil, one of the rarer 
members of that extensive genus. 
36. On the 29th of December, a snake belonging to a lit- 
tle-known species, the so-called horse snake {Chilomeniscus 
ephippicus), was received from Arizona. It is seldom that a 
more beautiful instance is afforded in nature, of the adapta- 
tion of structure to mode of life, than is displayed in the
