the pylorus to the cloacal aportures is al)out 87 mm. There 

 is no trace of a cfficum and I could not make sure where the 

 large intestine l)eg'au, becanse there were in the posterior 

 straight intestinal tract several constrietions with interme- 

 diate dilatations filled with faecal matter consisting chiefly 

 of chitinous remains of insects, that is as far as they could 

 he recognized. The posterior part of the intestine showed 

 the same appearance in several specimens, no trace of coäcum 

 which is the more stränge as Meckel (1. c.) enumerates Äm- 

 phishcena among such forms which are said to have a large 

 coecum. In a rather large specimen of Ampliishcena alha I 

 have seen a straight ccecum measuring about 6 mm. in length 

 b ut not very wide, and in Ampliishcena fnliginosa Cope^ re- 

 cords a ceecum as Meckel already had done before.

The peritoneum is black. The muscular ventricle is al- 

 most cylindrical and lies straight on the left side hardly re- 

 curved at the pylorus where a thinwalled portion about 5 

 mm. in length is fonnd. The small intestine measures about 

 155 mm. in length. There seems at first to be no real coe- 

 cum because the small intestine is attaehed to the anterior 

 end of the large intestine, but the small intestine extends 

 about 5 mm. along the large one coalesced to its dorsodex- 

 tral wall before it opens. There is thus formed a kind of 

 blind säck extending forward beyond the ileocolic opening 

 and this blind säck may be termed a coecum. The opening 

 of the small intestine protrudes into the large one and forms 

 thus an ileocolic valve. The large intestine forms a large 

 and wide säck about 40 mm. in length. There are no valves 

 in the large intestine, but posteriorly it shows some longi- 

 tudinal and also transversal folds which, however, do not 

 seem to be constant. The ventricle and the small intestine
