the intestinal mesentery on their way to and from the caecum a small 

 mesenteric fold (fig. 1, a) was attached for a short distance to the 

 csecum. The caecum is thrown into sacculations by four fibrous 

 bands running from end to end of the ca3cum and at approximately 

 equal distances from each other ; of these the band to wiiich the 

 ileo-csecal mesentery is attached is the least conspicuously developed. 

 This is rather remarkable, for in the Rhinoceros (Rh. sondaicus) the 

 band which lies on the opposite side of the caecum has disappeared, 

 and in the Horse is fused a considerable way before the end of the 

 caecum with one of the lateral bands'. 



At its commencement the colon was enormously enlarged and 

 intimately bound to the caecum i>y filirous bands as in the Rhino- 

 ceros. 



The looped arrangement of the colon is identical with that of the 

 Horse and Rliinoceros ; the distal narrow portion was not so dis- 

 tinctly marked as in Rhinoceros, but this apparent difference may be 

 really due to inflation. 



As in Rh. sondaicus each loop of the colon was furnished with 

 a considerable artery (fig. 1, d) and vein attached by a fold of mesen- 

 tery to the surface of the colon ; the blood-vessels and the folds were 

 continuous at the extremity of the loop. 



The American Tapir furthermore resembles the Rhinoceros in the 

 presence of a small free fold (fig. 1, e) wliich arises from the surface 

 of the membrane uniting the two halves of the colic loop. As will 

 be seen by a comparison of the accompanying drawing with the 

 figures of the Rhinoceros's caecum published by Mr. Treves and 

 myself (pi. xxxiv.), this fold appears to be on the opposite side. 



The omentum was large and bore some fat ; it was fixed to the 

 transverse colon and to the kidney. 



The spleen measured 13| inches in length and .3 inches greatest 

 breadth ; it liad a conspicuous notch on one side near to the broad 

 end. 



The liver is more like Murie's figure (4, plate iv. fig. 7) of the liver 

 of T. indicus than Parker's (10, woodcut fig. 2, p. 770). It has a 

 well-developed Spigelian and caudate lobe. The right central lobe 

 is larger than the left. There is of course no gall-bladder. 



The heart possesses a well-developed moderator band formed of 

 four limbs, of which three are attached to the free wall of the right 

 ventricle and one to the septal wall. According to Parker (10) this 

 structure does not occur in the Indian Tapir. As in that species, the 

 subclavian and carotid arteries all arise from a single innominate 

 trunk. 



The lungs agreed perfectly well with Parker's description of the 

 lungs in the Indian species. I noticed on the right side an epar- 

 terial bronchus. 



The generative organs I did not dissect ; the penis is well illus- 

 trated in Eudes-Deslongchamps's figures. 



^ Parker only describes three bands in T. indicus ; the one that has vanished 

 appears to be tlie one that is feebly developed in the American Tapir.
