11. One of the rarer macaws is the brown-fronted macaw 
{Ara severa), a species ranging from Nicaragua to Brazil — 
one of which was procured by purchase in June. At the 
present time tlie aviary contains an unusually fine series 
of this splendid group of parrots. 
12. A pair of Geoffroy's marmosets {Midas geoffroyi) from 
Panama, purchased on the 4th of July. 
13. On the 10th of July a specimen of the royal python 
{Python regius), a small species from western Africa, was also 
purchased. 
14. Among the most valued additions to the collection 
of reptiles, were five iguanas from the Isle of Pines, West 
Indies, procured by purchase on the 13th of July. These 
were at once seen to be different from any previously in 
the collection, and were subsequently identified by Pro- 
fessor E. D, Cope, as Cydura nuhila, Gray. It may be re- 
marked that the habit noticeable among the iguanas, of re- 
maining fixed in one position when the attention is excited, 
or of striking attitudes," is specially marked in these 
animals, and several of them being of large size, they have 
attracted considerable attention in the large case in the cen- 
tral portion of the new reptile house. They are of aggres- 
sive disposition, and cannot be readily handled, as they 
strike blows of astonishing force with their long tails, and 
bite with great tenacity an}^ object with which they are 
disturbed. As with the better-known iguanas, their most 
suitable food in captivity appears to be bananas, hen's 
eggs and milk. 
15. A male of the blue grosbeak {Guiraca ccerulea), one of 
our native birds, purchased July 14th. 
16. A violet-necked lory {Eos riciniata) from the Moluccas, 
also purchased. 
17. On the 25tli of July two specimens of the horned 
rattlesnake {Orotalus cerastes), one of the numerous serpents 
of this group, found in the Arizonian region, were presented 
by Dr. J. L. Wortman, of the Army Medical Museum. 
18. Two Hutchins' geese {Bernicla canadensis hutchinsi) 
were received from Nebraska on the 7th of August, and
