Wilks, Esq., C.M.Z.S., February 4th. This specimen was 
determined by Dr. Gray as belonging to his species Jacare 
longiscutata, and was of interest as indicating the true 
patria of this rare species. 
2. A Smooth-headed Capuchin Monkey (Cebus mona- 
chus, F. Cuv.), remarkable for its large head covered with 
short recumbent hairs, very different from those of the 
Cebi ordinarily seen in the Society’s Menagerie, where this 
species is believed to have never been exhibited before. 
The present individual was deposited by Mrs. Pascoe 
Dupré Grenfell, on the 26th of February. 
3. A Thick-tailed Opossum (Didelphys crassicaudata, 
Desm.), from the Argentine Republic, presented by George 
Wilks, Esq., C.M.Z.S., March 5th, being a fine example 
of this rare species. 
4. A Burrowing Owl (Pholeoptyne cunicularia, Mol.) 
from the same locality, and presented by the same donor.

habits, it excavated a hole in the soil at the bottom, into 
which it always retreats when threatened.

same locality.

lace, P. Z. S. 1862, p. 336) from Celebes.

Hon. John Ellis, April 21st, making up a pair of this 
extraordinary bird then living in the Society’s Gardens.

argentata, Linn.), purchased of a Liverpool dealer, and 
stated to have been received from the Amazons. 
10. A pair of the Wild Ass of the Syrian deserts (Equus 
hemippus of the late Isidore Geoffroy St.-Hilaire), of much 
interest as rendering the Society’s series of the living 
species of this group complete. ‘This pair of animals was 
obtained by exchange from the Jardin d’Acclimatation, 
Paris, on the 2nd of May.

cephalus), purchased on May 14th, being the first specimen
