1 . One 4-zoned monarchaxine homozone, with principal polar tes- 

 saraces, and amphigrammic zoneless axes. The zone is 



Z={2 p +2.1, 2.1, 2 - 1 }- 



2. One homozone triaxine, with zoned polar tessaraces, and am- 

 phigrammic zoneless axes. The zone is Z = {2 1 ,, 2.2, O 2 - 1 }. 



3. One 2-ple monaxine monozone, with amphigrammic axis. The 

 zone is Z = {2.1, 2.2, 2 -i}. 



4. Two 2-zoned monaxine heteroids, one with amphigrammic 

 axis, having the zones 



Z={2.2, 2.1, P , O p) O 2 - 1 }, Z'={2.1, 2.1, Op, P },
