globular pouch or ececum, not unlike the rudhmentary ccecum found in 

 some land Tortoises. From this pouch to the anus the distiince was 

 5 inches. The intestinal canal was full of purulent matter, and its 

 mucous coat was highly inflamed. 1 found no worms, though I looked 

 carefully for them, opening nearly the whole of the alimentary canal. 



" The oviduct and the ureters terminated in the cloaca as usual. 

 The ovary was nearly ^ of an inch long. The kidneys were as usual, 



" The eyes approximated closely in structure to those of the Parrot 

 tribe. The sclerotic coat had a narrow ring of ossification composed 

 of eleven plates, six of which were disposed in an imbricated manner, 

 the five at the lower and posterior part being only in juxtaposition. 

 Of these plates, however, the three superior alone could be termed 

 fairly osseous. The cornea was small in diameter and not very convex. 

 The optic nerve entered the infero-posterior portion of the sclerotic, 

 the retina springing from a tubercle under and around the marsupium, 

 which was very small. The vitreous humour and lens were as usual. 

 The membrana aquatica, as it is termed, was very visible. The ciliary 

 processes, the 12th of an inch long, were 96 in number. The uvea 

 was darkj the iris lake colour, and its sphincter fibres distinct; the 

 ciliary ligament broad ; the pigvientum nigrum dark brown and in 

 large quantity. Many fibrils of the 3rd, 4th, and 5th pairs of nerves 

 pierced the sclerotic." 



Mr. Bennett directed the attention of the Meeting to an interest- 

 ing series of the Indian Antelope, Antilope Cervicapra, Pall., now at 

 the Society's Gardens. It consists of four individuals : an adult and 

 aged male, brought by Col. Sykes from Bombay, and presented by him 

 to the Society nearly five years ago j a younger, yet adult, male, which 

 was presented, in an immature condition, about two years since j an 

 immature male, lately arrived in the Menagerie, and in about the 

 same state of development as that in which the last-mentioned indi- 

 vidual was when it was originally presented j and an emasculated in- 

 dividual of full growth. In the oV^ex oi ihesQ Antelopes the rich deep 

 colour of the body generally is so intense as almost to approach to 

 black, and the horns are strong and fully developed : the possession 

 of horns and the depth of colouring, which are peculiar to the male 

 sex, are exhibited in it at their maximum. The second individual ap- 

 proximates nearly to it in the degree in which these secondary sexual 

 characters are developed. In the third, the youngest of the series, 

 there exist the horns characteristic of the male, but these organs are 

 yet of small growth, are only beginning to be annulated at their base, 

 and are commencing their first spiral turn ; its colour, as is very 

 generally the case among the young of animals that in adult age are 

 differently coloured in the sexes, is that of the female, which in this 

 instance is a dull fawn with a pale stripe along the side : it has, con- 

 sequently, in these two striking particulars, full evidence of immatu- 

 rity. The emasculated individual was probably, at the period when
