Remarks. — The cmymyonic, ampliiclinous, and prozonal appear- 

 ance, with myoplane 3-3i/^, of the foregoing specimens leads to the 

 conclusion that they probably belong to D. gegenhauri. Among them, 

 two groups are discernible : one with body muscles III and IV broader 

 than the others; the other with only body muscle III broader than 

 the others.
