CALLITHRIX SCIUREUS. 27 



lying in the curve of the duodenum. The epiploon adheres to the great 

 curve of the stomach and to the root of mesentery, not to the colon. 



The liver has four lobes ; one on the left of the gall-bladder-lobe, 

 and two on the right, the lowest of which, or the most to the right, is 

 carried in behind the vena portse, and has the lobulus Spigelii standing 

 upon it. The gall-bladder adheres near to the aorta, not coming nearly 

 so low as the edge of the liver. The kidneys are as in the monkey. 

 The urinary bladder is very long. 



[The Squirrel-monkey, or Naked-tailed Monkey of Shaw, 

 'General Zoology/ vol. i. p. 77 (Callithrix Sciureus, Linn.).] 



An animal something larger than a sanguine ; not so much hair on 

 its head and cheeks : has a longer tail, which has but very little hair 

 upon it ; but the hair on its body is similar to that of the sanguine. 

 Its manners and way of life seem to be the same with those of the 

 sanguine. 



There are claws on all the fingers of the fore-foot or hand 1 , therefore 

 the thumb is in a line with fingers, and is not a counteractor to the 

 fingers. There is a nail on the great toe ; therefore it is in some 

 measure a counteractor to the other toes, 



The lungs are as in the sanguine. 



The stomach, duodenum, and colon are similar to those in the sanguine. 

 The csecuin is a pouch about an inch long. The pancreas and epiploon 

 are as in the sanguine. The spleen is a long body lying in the epiploon, 

 pretty close to the stomach. 



The liver is as in the sanguine, only that the lobe on the left of the 

 gall-bladder-lobe is somewhat attached to that lobe. The gall-bladder- 

 lobe has a deep fissure in it, for the vein. The gall-bladder is situated 

 in the same way [as in the sanguine] : it makes some turns upon itself 

 near the neck. 



The kidney is conglobate and pretty prominent. The capsula renalis 

 stands on its upper end like an apex. 



The penis is prominent, like the human, although more coverable by 

 the prepuce, which does not run along the belly. The scrotum is 

 shallow, which does not allow the testicle to go far beyond the penis. 

 There is a tunica vaginalis communis [i. e. it communicates with the 

 peritoneal cavity, from which it was originally derived].
