Table A. 



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

 tetragons, and amphigrammic zoneless axes. The zone is first read 

 in Table B below. 



2. One homozone triaxine, with zoned tetragon poles, and amphi- 

 grammic zoneless axes, with zone next read in Table B. 



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

 the zone Z={2.2, 2.1, O 2 - 1 }. 



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

 axis, having the zones 



Z={2.1, 2.2, O,, <V 02-1}, Z'={2.1, 2.1, Op 0,}, 

 the other with amphigonal axis, carrying a hexace and a tessarace, 

 with the zones 



Z={2.l p , 2.2, 02-1}, Z'={2.1^+2.1, 2.1, O 2 - 1 }. 



5. Eight zoneless 2-ple monaxine heteroids, one having an am- 

 phigonal axis, and seven with amphigrammic axes. 



C. Nineteen monozones, of which 



6 have the zone Z = {4, %, O 3 , 0}, 



1 has the zone Z = {4, 2, O 2 }, 



2 have the zone Z={4, 4, O 2 , O 2 }, 



3 have the zone Z = {2, 4, O 2 },
