comparatively smooth with the orifices of the ureters situated well in on its sides, 

 with rather patulous orifices directed inwards and downwards. The orifices of 

 the cloacal bladders are very wide, as in aU Batagurs, and distensible, easily dilating 

 to two inches and a half m extent. The whole of the inner walls of the bladders are 

 covered with villiform processes, as in Fangshura, very sparse near their apices 

 but especially plentiful at then- orifices, and on the sides of the cloacal canal nearly 

 as far forwards as the clitoris. The latter organ has two lateral lobes on either 

 side, with a common, somewhat pointed anterior lobe, with a small central lobe 

 resembling the last, and grooved for the termination of the urinary canal. The 

 urinary canal is three inches in length, and it dilates in its anterior third as it 

 approaches the orifice of the ureters. The allantoic bladder is very large, and 

 the fundus of its right division is attached as far forward as the liver by a narrow 

 mesentery. A specimen which had lived for two months without water beyond an 

 occasional douche, but which had not been near water for three weeks before its 

 death, except on the previous day when it was immersed, the bladder was found 

 distended to a great size with a clear fluid, and so large as to invest the whole of 

 the intestines, reaching to both lobes of the liver. 



The trachea divides at 6-75 inches from the laryngeal sht and is to the left of 

 the mesial line. The right and left bronchi are 7"50 inches long, and in their length 

 and convolutions resemble the coiled air-tubes of some birds. The left bronchus is 

 completely curved upon itself at the apex of the left lung, anterior to which it lies 

 along the anterior border of the oesophagus till it reaches the apex of the lung where 

 it describes the foregoing curve, and then crosses the dorsal aspect of the oesophagus 

 to enter the lung about two inches below its apex and one inch internal to the 

 inner border of the lung. The right bronchus enters its lung at about the same posi- 

 tion, but does not curve on itself like the left tube, but in its course from the 

 trachea describes a number of small curves. 



The lung is six inches in extreme length, by three inches in breadth. It is 

 broad anteriorly and narrower behind. Its external margin is marked by six 

 divisions, the most anterior being the largest, and forming the outer half of the broad 

 anterior end of the lung and is partially divided into three secondary lobules. The 

 posterior division is not very long, but is divergent from the lobe before it. The 

 inner border terminates in a moderately long dilatation, projecting backwards across 

 the ovaries and separated from the last lobe of the outer border by a wide notch.
