of the abdomen. The lowest and largest superficial loop was formed 

 by the duodenum, and the whole were hid by an omental covering 

 thickly charged with fat. 



The interspace of the duodenum was occupied by the two lobes of 

 a narrow and elongated j?awcre«s, the pointed extremity of the an- 

 terior lobe extending freely beyond the bend of the duodenum, and 

 immediately beneath it appeared the end of the rectum and cloaca. 



Upon dissecting away the omental processes and raising the ex- 

 posed loops of intestine, the rectum was seen extending forwards 

 about two inches along the mesial line, and then receiving the ilium 

 and extremities of two c(£ca : the anterior half only of the rectum had 

 an investment oi peritoneum. 



Upon raising the liver, and drawing aside the stomach, the duo- 

 denal loop was seen extending in a curved direction, and about four 

 inches in length, from the right side of the gizzard as before noticed ; 

 having formed that loop, the intestine bends abruptly backwards, 

 upon itself to the right, and then forms a second loop three and a 

 half inches long, which is continued down the right side of the ab- 

 domen. Three similar but somewhat shorter loops are there formed 

 to the left of the preceding, after which the intestine returns to near 

 the commencement of the duodenum behind the stomach, and close 

 to the root of the mesentery, whence it descends to form a fifth long 

 loop situated at the left side of the abdomen behind the others, and 

 then becoming looser terminates after a short convolution in the 

 rectum. 



The cacu were each five inches in length, and attached throughout 

 their whole extent to diiferent parts of the last folds of the ilium. 



The small intestines had a general diameter of three lines, their 

 size slightly diminishing on approaching the rectum. The c<cca at 

 their commencement rather exceeded in diameter that of the ilium, 

 their capacity slightly increasing to near their blind extremities, 

 where, having attained the diameter of about five Hnes, they sud- 

 denly taper to an obtuse ])oint. The anterior half of the rectum 

 was contracted and the lining membrane thrown into longitudinal 

 folds, but these gradually subsided in the second or dilated portion. 

 The rectum communicated with the urinary dilatation by a small 

 semilunar aperture, from wliich several short ruga radiated. This 

 compartment of the cloaca was not expanded into a large receptacle 

 as in the Ostrich, but offered the same proi)ortional size as in the 

 Emeu, measuring about two-thirds of an inch in length and the 

 same in diameter. The external compartment of the cloaca con- 

 tained a large single /jew/s retracted spirally, and one inch and a half in 

 length when extended. It was traversed by an urethral groove, the 

 sides of which were not beset with papilla as in the Gander, but 

 simply wrinkled transversely. At the back part of the cloaca there 

 was a small bursa half an inch in length, and communicating by a 

 wide longitudinal aperture with the external compartment. 



The gizzard contained a greenish yellow pulpy substance, and 

 numerous filamentary bodies, amongst which a few slender legs of
