358 REPTILIA. 



The pancreas is very small, lying in the first curve of the first intes- 

 tine. This gland bears a much smaller proportion to the liver [than in 

 mammals]. The liver has two lobes, right and left, united in the 

 middle, by a continuation of substance. The spleen is a round body 

 lying behind the stomach. 



The coronary artery arose, in one specimen, from the subclavian on 

 the right, in another from the fore-part of the right aorta. The bladder 

 is an oblong bag laterally, the long axis being from right to left, 

 answering to the breadth of the abdomen : it appears to come out 

 from the side [of the cloaca] and opens into the rectum [uro-genital 

 canal] . 



The lungs of this genus are [proportionally] much larger than [those 

 of] the turtle : they fill the whole back, as low as the extremity of the 

 pelvis, having almost every viscus adhering to their anterior surface, 

 but they are thrown into a large irregular cavity, more especially at 

 the lower end. There is not a branching trachea dividing into cells as 

 in the turtle 1 . 



Of the Male Parts. — The male parts consist of two testicles, vasa 

 deferentia and penis. The two testicles lie on each side of the rectum, 

 before the lower end of the lungs : they are pretty large bodies. The 

 vas deferens goes out from the [upper and inner] end ; and as it passes 

 down it is very much convoluted, forming a body, like the epididymis. 

 This body is of a dark colour, having a dark covering, and the [con- 

 volutions of the] duct are united by dark cellular membrane. The last 

 part passes along with the ureter, as it is passing from the kidney to 

 the bladder, and they both open together into the urethra [uro-genital 

 canal] before it opens into the rectum 2 . The penis is long, and begins 

 as the clitoris ; but the projecting part is of considerable length. It 

 can be pulled out of the anus more than two inches ; it has a deep 

 groove passing through the whole length. It has much the appear- 

 ance of a tongue. It begins by two kinds of crura, which are spongy, 

 and the veins about each crus are large, so as to give fullness to these 

 parts. 



Of the Female Parts. — There is an ovarium on each side, of a yellow 

 colour, situated on each side of the rectum. They are near 2 inches 

 long, half an inch broad in the middle, and very thin, having one edge 

 attached to the surface of the lungs by a thin membrane. They are 

 granulated. The oviducts begin laterally on the fore-part of the lungs,
