great smd unifoim capacity ; but in Phcenicopterus it is not more than 

 half an inch in diameter wlien dilated. At tiie lovver pait of the neck 

 it expands into a considerable pouch, which measured in the specimen 

 here described 3 inches in diameter, and 4\ inches in length. In 

 Perrault's specimen the diameter vvas only 1^ inch, and it vvas pro- 

 bably in a statė of contraction, as he describes it as furnished internally 

 with many small longitudinal rugce. The circular fibres around this 

 partvvere very distinct. Beyond this pouch the cesophagus agAin con- 

 tracts to about 4 lines in diameter, and so continues for 34^inches, whea 

 it terminates in the provenlriculus. This glandular cavity was 1 inch 

 8 lines in length, and 5 lines in diameter : the gastric follicles were 

 broad, short, and simple, and were arranged in tvvo long oval groups, 

 blending together at the edges. The provenlriculus terminates in a 

 small but-strong gizzard, of a flattened spheroidal form, measuring 

 1 inch 5 lines in length, and the šame in breadth ; the lateral museles 

 were each half an inch in thickness. The gizzard was lined with a 

 moderately thick and yellovv-coloured cuticle, disposed in longitudinal 

 ridges, the extremities of vvhich projecting into the pyloric aperture 

 form a kind of valve, as in the gizzard of the Ostrich. In a Flamingo 

 dissected by Col. Sykes, in vvhich the duodenum was blocked up by 

 tvvo large tape-tvorms, the museles of the gizzard were i inch in 

 thickness. 



"The duodenal fold extended tovvards the left side 4 inches from 

 the pyloms. This intestine vvas 4 inches in diameter. The pancrea*, 

 vvhich occupied its common situation betvveen the tvvo portions of the 

 fold, had a more complete peritoneal covering than usual. The in- 

 testinal canal soon diminished in diameter to 3 and then to 2 lines. 

 The small intestines formed an oval mass, and vvere disposed in tvventy- 

 one elliptical spirai convolutions, eleven descending tovvards the rec^Mjre 

 and ten returning tovvards the gizzard in the interspaces of the pre- 

 ceding ; a disposition analogous to that of tlie colon in Ruminants. 

 The villi of the intestines vvere arranged in longitudinal zigzag lines. 

 There vvere tvvo c^ca, each about 3-į- inches in length and 5 inches in 

 diameter. 



" The testes vvere about the size of grains of vvheat, and vvere situated 

 on the anterior part of the renal capsules. The latter bodies vvere 

 about the size of hazel-nuts. Both these glands vvere of a bright 

 yellovv colour. The fat of this bird is of a remarkable orange tint. 



"The principai diseased appearances vvere in the lungs, vvhich vvere 

 filled vvith tubercles and vomicce. I vvas much struck with finding the" 

 inner surface of the latter cavities, and that of mest of the smaller ra- 

 noifications of the bronchial tubes, covered over vvith a green vegetable 

 mould or mucor. As the individual vvas examined within 24 hours 

 after its death, it seemed reasonable to conclude this mucor had grovvn 

 there during the life-time of the animal. Thus it vvould appear that 

 internal parasites are not exclusively derived from the animal kingdom, 

 but that there are Entophyta as vvell as Entozoa. 



"The tongue of the Flamingo is remarkable for its texture, mag- 

 nitude and peculiar armature. It is almost cylindrical, but slightly 

 flattened above, and obliąuely truncate anteriorly, so as to correspond
