 very narrow septum indeed between the wide mouths of the finger- 

 lilje appendages.

Ciecam of Manatus inunguis. 



C, cjecum ; D, its two diverticula ; /, fold of mesentery ; gl, a coiled 

 mesenteric lymphatic gland. 



The liver ol: Manatus latirostris has been described without 

 figures by Murie and mth figures by Garrod. If I had not 

 had the opportunity of seeing the actual liver myself I should 

 have found certain well-marked differences between the two 

 species which are really non-existent. The organ in fact varies in 

 form to some extent. Garrod's figures agree more closely on the 

 whole with the liver of M. immgxds than with that of the individual 

 of M. latirostris which I have studied myself. Garrod figures 

 the central lobe of the right half of the organ as being but little 

 separated from its lateral lobe, than which it is much smaller. In 

 my specimens, both of M. latiroatris and M. inunguis, the separation 

 was much more marked. The left lateral lobe of M. latirostris, 

 according to Garrod, is fairly notched on its lower border ; it agrees, 

 in fact, closely with M. inunguis, but not with the M. latirostris 

 dissected by myself. On the under surface of the left lateral lobe 

 in M. latirostris 1 found a deep rounded cavity, which appeared 

 to have lodged during life the glandular appendix of the stomach. 

 This was so deep that it very nearly perforated the liver tissue. I 

 observed nothing of the kind in M, inunguis. The gall-bladder, as 

 in M. latirostris, is large ; it was not so fully overlapped by a 

 triangular piece of the right lobe as in M. latirostris, as figured by 

 Garrod and observed by myself. 



The kidneys of Manatihs latirostris have been described rather
