Distance from snout to vent 87 mm. The peritoneum is brownish black. 



The ventricle reaches nearly to the ingainal region and 

 is a litte cnrved inward, but not forward at the pylorus. The 

 beginning part of the small intestine is strongly widened in 

 such an abrnpt manner that it almost forms a small ccccal 

 appendage on the posterior side. There is a well developed 

 pyloric valve and between this and the main muscnlar ven- 

 tricle is a short thin walled portion. The mucosa of the 

 small intestine is laid into a number of large folds. The 

 length of the small intestine is about 82 mm. It opens on 

 the left side of the large intestine, which is prolonged, for- 

 ward and dorsall}^, so as to form a ratlier large coecnm mea- 

 snring 5 mm. in length from the ileal opening and almost 

 as much in width at first, l)ut tapers to a width of 2^2 mm, 

 at the blind end. The large intestine is wide and measnres 

 about 33 mm. in length. The opening of the small intestine 

 protrudes a little into the cavity of the large one, on the 

 ventral side of the opening into the coocum. The ccEcum is 

 strongly attached to the back of the abdominal cavity by 

 means of mesentery along its dorsosinistral side so that the 

 greater part of the coecal säck lies on the right side of the 

 mesentery but its blind end penetrates the same and appears 

 on the left side. The large intestine was filled with remains 

 of beetles and other insects.

Distance from suout to vent 120 mm. 



The ventricle is spindle-shaped and lies nearly straight 

 along the left side of the abdominal cavity extending almost 

 to the inguinal region. The straight main portion of the ven- 

 tricle is strongly muscular, but the thick muscular coat ceases 

 suddenly and then follows after a slight constriction a short 

 thin walled and dilated portion. This one is about 5 mm. 

 long and opens through a pyloric valve into the small in-
