also soine few pieces of vegetable origiii. The latter ha ve, 

 however, probably been svvallowed accidentally together with 

 the insects. 



The limit between the veutricle and the duodenum at tlie 

 pylorus is valve-like. The length of the small intestine is 

 i>6 mm. Its mucosa is longitudinally plicated and the plietB 

 are wavy. 



There is a somewhat recurved coecum, (i mm. in length, 

 and not much dilated, basallj^ 5 mm. in diameter. The iipper 

 part of the large intestine forms in this specimen an ampulla 

 of abont the same width as the ccecam and 9 mm. in length, 

 then it is narrowed to 3 mm. for a length af about 10 mm. 

 and then passes into a rectum about 2 cm. in length. The 

 latter is anteriorly widened so that its diameter is 8— 10 mm. 

 AVhen the colon is completely filled, it has the same width 

 all along to the anus as I have stated in another specimen. 



From the ileocoecal opening extends a transversal plica which 

 may be interpreted as a slight coeco-colic valve, otherwise 

 there are no valves in the large intestine. In the empty por- 

 tion it was longitudinally plicated which condition of course 

 only is of a passing nature.

Distance from snout to vent 298 mm. The peritoneum is black. 



The ventricle is crescent-shaped the pylorus being re- 

 curved forward and to the median line. The posterior cur- 

 vature lies at a distance from the inguinal region which 

 represents about two sevenths (perhaps when it is better 

 filled only a fourth) of the distance between axilla and 

 groin. There is a well developed pyloric valve measuring 

 4 — 5 mm. in height, but on a distance of nearly 1 ^'2 cm. from 

 the valve the walls of the ventricle cease to be muscular so 

 that there is a sharply defined thin-walled portion of the ven- 

 tricle between the valve and the main cavity. There seems 

 to be no special sphincter limiting this thin-walled portion, 

 but there is nothing prohibiting a local constriction of the 

 muscles of the ventricle from doing so, when it is needed. 

 The interiör of both portions of the ventricle has longitudi- 

 nal folds. There is as usual a strong mesenteric band between
