Even if different methods of measuring may have given different 

 results it seeins to be certain that the small intestines of Tatusia 

 are comparatively rauch longer than those of Dasypus. Dasypus 

 6-cinctus has according to Owen's measurements the small in- 

 testines about 10 times longer than head and body, thus more 

 than ten times the length of the carapace. According to Alles- 

 SANDRlNl's measurements the relation between the small intestines 

 and the carapace seems to be in the same species 9 1 / 2 - Although 

 no exact results can be gained from this, it seems however as if 

 I), minutus should approach Tolypeutes with regard to the short- 

 ness of the small intestines. In that form namely, the relation 

 between the small intestines and the carapace seems be about 

 6V2 (according to Murie's measurements). 



The great gut is about S 1 ,^ cm. longer than the length of the 

 carapace. There is no proper ileo-ccecal valve, but the small 

 intestine is narrowed where it enters the great gut, and shows 

 on its inside about half a dozen longitudinal ridges. 



There are two lateral colic coeca. They are not quite 1 cm. 

 long and have nearly the same width. This must be compared 

 with Fauvel's words concerning I), villosus (1. c): »L'intestin 

 assez long ne présente pas de ceecum». It seems to be of in- 

 terest to know that two so closely allied species as D. villosus 

 and D. minutus differ in this respect so that the latter has, 

 the former misses colic cceca; the more so as the presence of 

 colic coeca is a feature that has been regarded as common to the 

 whole genus Dasypus as well as Chlamydophorus. 



The great gut and the coeca contained a very large number 

 of small nematods of the genus Heterakis. They were however 

 not in such a state of preservation that the species could be 

 determined. This was also the case with two strobilae of a 

 species of Tcenia in the small intestines, and some Aspidocephali 

 in the stomach. 



The spleen is triangulär, with the two basal lobes rounded, 

 but the third median very long and acuminate. It has the 

 usual position, adherent to the left underside of the stomach by
