generally is the case in the Spider Monkeys (Ateles). As regards 

 its admeasurements, I noted : — Distance between the oesophagus 

 and the great curvature 2*2 inches ; diameter or width from the 

 cardiac to oesophageal ends 4 '8 inches; greatest diameter of the 

 cardiac end 1*6 inch; the upper or lesser curvature 3 - 2 inches; 

 width of the oesophagus as it enters the stomach £ inch. These 

 computations I presume were made on the empty viscus.

Macacus maurus = M. inornatuz, female. 



The small intestines had a length of 6 1 inches. The ileum nar- 

 rows slightly as it joins the great intestine, its diameter being 

 - 7 inch. Caecum short and wide, viz. 1*7 inch long, and T4 inch 

 wide. Including the csecal appendage, the great intestine measures 

 25^ inches. For the first 5 inches it is wide, then narrows by de- 

 grees to the rectum, where it is less than 1 inch in diameter. The 

 longitudinal bands are strong, and the sacculations few, beyond 7 or 

 8 inches from the commencement of the gut. 



The lungs were quite healthy, trilobed, with an additional lobule 

 or lobus impar. The spleen was immensely enlarged, congested, 

 and had distributed throughout its substance numerous encysted 

 abscesses averaging the size of peas. Kidneys of the usual oval 

 contour, the right the larger by a quarter of an inch. 



Of the liver, the left lobe may be said to be the largest and 

 flattest. Its borders are slightly scolloped, producing several angles ; 

 but there are no deep grooves or indentations ; the entire lobe is well 

 nigh cut off from the others, the union being by a narrow pedicle. 

 The right lobe is thick and oval-shaped. The gall-bladder is sunk 

 deeply into the cystic lobe, the left surface of the latter having a 

 projecting lobule and two shallow clefts. Both Spigelian and cau-
