34 QUADRUMANA. 



The general character of the two are very similar ; so much so, that if 

 not viewed together, they might be supposed to be the same species. 

 However, when critically compared, there is a considerable difference, 

 and probably that is in the length of the extremities. The Lemur 

 tardigradus approaches nearer the monkey 1 : the terminations of the 

 extremities, or what are called hands or feet, are the same. The face 

 is short, and of a singular shape ; a broad forehead pointed at the nose, 

 and the lower jaw sloping off quick, so there is no chin. The face is 

 pretty straight from forehead to nose, only a little hollowed at the root 

 of the nose : from the eyes being very prominent and looking almost 

 directly forwards, they make a part of the face. No tail 2 . Ears promi- 

 nent, thin, and with many processes on the hollow side. Nails on all 

 the fingers and thumbs, excepting the fore-finger of the feet, which is 

 a claw 3 , as in the other [viz. Lemur gracilis?] 4 '. 



The oesophagus is pretty long below the diaphragm 5 . The stomach 

 is round or globular. The pylorus arises near to the tennination of the 

 oesophagus, but not so close as in the other. The duodenum, as usual, 

 goes in some degree to the left and becomes a loose intestine. The 

 ileum passes into the colon on the right. The whole small intestines 

 are not long : there are no valvulae conniventes in the intestines. The 

 coscum is long, but not so pyramidal as in the other [viz. Lemur tardi- 

 gradus']. The colon passes up the right side, and where it is going to 

 cross the abdomen, it makes a slight fold on itself, then passes to the 

 left, and down close to the back, to the pelvis, where it becomes the 

 rectum, without any sigmoid flexure 6 . 



The epiploon is attached to the great curve of the stomach and 

 transverse arch of the colon, as also to the eras of the diaphragm, 

 between the stomach and colon. 



The spleen is a long small body, as it were suspended in the epiploon, 

 along the left and lower curve of the stomach. 



The liver has four lobes, besides the lobulus Spigelii : the left lobe is 

 the largest ; the second from the left, or that which has the gall-bladder 

 attached to it, as also the round ligament, is next in size, and is nearly 

 in the middle of the abdomen ; and where the round ligament enters 

 there is a small lobe. 



The left end of the pancreas is, as it were, suspended in the posterior 



1 [In the L. gracilis the fore-arm and leg are longer and more slender.] 



2 [The tail is represented by a mere stump (" cauda brevissima," Fischer) : in L. 

 gracilis this rudiment is absent.]
