300 LÖNNBERG. ON DASYPUS MINÜTÜS. 



The sto mach is not globular as it is described by Owen 

 from Tatusia 9-cincta (Proc. Zool. Soc, Part. I, London 1830 — 31) 

 nor is it suddenly contracted at the pyloric end as in that form 

 or in Tolypeutes tricinctus (Murie: Trans. Linn. Soc, London, 

 Vol. XXX). It is transversely extended. Its longest diameter 

 is about 7 cm., and the width or depth is at the fundus end 

 just as great as at the pyloric end, with a diameter of not quite 

 3 cm. The distance from the middle of the stomach to the 

 pylorus is about 1 cm. longer than to the other end. The in- 

 teriör surface of the stomach resembles that of 9-cincta (Owen) 

 and Tolypeutes (Murie) to a certain extent. The cardiac por- 

 tion has a smooth villous membrane, but the pyloric shows a 

 good many, well marked, partly forked rugse, and the muscular 

 coat is here much thicker. At the pylorus there are two thick 

 semilunar ridges, or valves, situated at opposite sides, but not 

 at the same height, the upper one, that is the one nearer the 

 lumen of the stomach, being much thicker. This one probably 

 corresponds to the protuberance described by Owen from Tatusia. 

 Tolypeutes is said to have no valvulär apparatus and this is 

 also the case with Dasypus Q-cinctus. 



The content of the stomach was composed of a blackish 

 mäss in which were found legs and wings of beetles and other 

 insects, larvae and worms. Although killed in wintertime the 

 animal thus seems to have made excursions for the purpose of 

 seeking food. 



The length of the small intestines is about 14 cm., mea- 

 sured with a thread along its convolutions while it was yet ad- 

 herent to the inesenterium. This length is about 8 times that of 

 the carapace. In Tatusia the relation between the length of 

 body and that of the small intestines seems to be quite diffe- 

 rent as Owen in a specimen which measured 1 foot 1 inch from 

 »the end of the nose to the setting on of the tall», found the 

 small intestines to be »18 feet» in length. Rapp (quoted by 

 Alessandrini) says that in the Tatusia peba »la lunghezza del 

 tronco stå a quella dell'intestino come uno a diaci od undici».
