CYCLODUS. 369 



tearing * : this is similar to the scineus. The tongue is both very broad 

 and long 2 . 



The oesophagus is large, and is continued into the stomach without 

 changing its direction, so that the oesophagus and stomach form one 

 continued tube ; only that the stomach is rather thicker in its coats. 

 The first intestine makes a turn out towards the right; then makes 

 two or three convolutions as it passes downwards to terminate in the 

 colon. The colon, or what may be called the rectum, is pretty large at 

 its beginning, becoming rather smaller towards the anus. The intes- 

 tines are very short, not exceeding the length of the animal from mouth 

 to anus. 



In the stomach I found vegetable substances; some seeds, which 

 probably were of some fruit ; some fibrous substance like weeds or the 

 bark of a tree ; and even some pieces of wood which was rendered 

 very soft, but whether by the stomach, or naturally so, I do not judge. 



Between the anus and back-bone are two glandular substances, but 

 whether they have ducts or not I do not know. 



The liver is, as it were, forked, dividing into two ; one lobe passing- 

 down the right, which is continued into a long process into which the 

 vena cava inferior enters. The vena portarum enters the sulcus or 

 union of the lobes. The liver is attached forwards by two membranes, 

 one to each lobe, which unite at top : the same takes place behind. 

 The gall-bladder lies in a sulcus made by the union of the two lobes of 

 the liver. The spleen lies behind the stomach. The whole of the above 

 viscera are attached to the back by four membranes. The kidneys lie 

 in the lower part of the abdomen, close to the spine; they are long 

 bodies terminating in a point at the upper end. There is a small bladder 

 before the rectum. The testicles are pretty large oblong bodies, the 

 light the highest : the tubular substance is very loose 3 . 



The heart consists of two auricles, with two ventricles intercommu- 

 nicating. The valve of the ventricle is attached to the septum of the 

 auricle. The lungs are two large oval bags, which are honeycombed 

 at the upper ends, becoming gradually less so towards their blind ends. 

 The trachea is very flexible. All about the trachea and oesophagus 

 above the heart, there is a cellular texture which is easily inflated.
