776 REPTILIA. 



individual was 11-50 inches and of the lesser curvature 7'80 inches, with a maximum 

 diameter of I^'IO. The total length of the small intestine was 45"-60, and of the 

 large intestine 15"'60. There is a small conical dilatation of the large intestine 

 on the begianing of its left wall. The first five inches of the small intestine are 

 considerably dilated and the mucous coat is smooth, but beyond that, to the large 

 intestine, there are long tracts in which it is thrown into long continuous wavy 

 parallel rugse of different calibre, but of marked regularity. The fiver is rather small 

 compared with B. lineata, and its right and left lobes lie immediately behind the 

 septa, its right being but little larger than its left lobe. The latter has a Ungulate 

 anterior surface directed backwards and inwards, from left to right, with the 

 tip recurved outwards, the peritoneal sac being alone attached along the upper 

 border. Its outer haL£ fies across the oesophageal portion of the stomach, the 

 recurved inner end resting in the depth of the smaller curvature. This lobe has 

 two small lobiiles at its base, dorsal to the attachment of the gastro-hepatic omentum, 

 and they also lie in the smaller curvature, the smaller lobule being bent anteriorly 

 over the root of the other, and fitting into the lesser curvature. The other lobule 

 contracts rapidly and in the middle line is not more than 0'75 of an inch in breadth 

 antero-posteriorly, while its transverse width is three inches. The two vence cavce 

 run along the anterior surface of this connecting lobe {lobidus caudatiis), the heart 

 resting on it about its middle. The right section of the liver is deeply concave, 

 chiefly by the inward projection of the ventral half of the right lobe which is 

 broadly bifurcate at its extremity, and to which the allantoic bladder is attached, 

 and by the dorsal half of this lobe meeting the lohulus qimdratws at right angles. 

 The lobiilus quaclratus sends down a long filamentary process from its inner margin, 

 beliind the gall duct, and along it the vena cava passes. The gall bladder which is 

 large is so deeply imbedded in the right lobe that its fundus aj)pears on the exter- 

 nal surface of the liver as a round projection close to the margin between the two 

 divisions of the right lobe. The bile duct has a course of about six inches, and 

 opens into the intestine, six inches from the pylorus. The bile is a very dark-green, 

 almost approaching to black. 



The pericardium was full of a very clear fluid which measured about 2 ounces. 

 The right auricle was beating vigorously for about two hours after all external 

 signs of life had ceased, but the other cavities exhibited hardly, if any, perceptible 

 movements, any motions that they did make appeared more to be due to the blood 

 propelled by the right auricle and to its movements. The right auricle has thin, 

 almost transparent puckered walls and is considerably larger than the left auricle. 

 Its apex is directed inward, and slightly forward. The pulmonary artery divides 

 at 0-68 inch from its base, and the brachial arteries arise one inch from the base 

 of the ascending carotid. The right descending aorta, lying between the piilmonary 

 artery and ascending carotid, bends over to the right nearly in a transverse direction, 

 crossing the left carotid, left and right bronchi, and bending round about the middle 

 of the left bronchus reaches the back. The right aorta gives off at 0-75 of an inch 

 from its base, a common trimk, a quarter of an inch in length, which divides into the
