Among the 42 glyphs (maybe 3 weeks) from pito to the end of the line I have redmarked a few of the significant ones:
 
Ab8-43 Ab8-44 Ab8-45 Ab8-46 Ab8-47 Ab8-48
Ab8-49 Ab8-50 Ab8-51 Ab8-52 Ab8-53 Ab8-54
Ab8-55 Ab8-56 Ab8-57 Ab8-58 Ab8-59 Ab8-60
Ab8-61 Ab8-62 Ab8-63 Ab8-64 Ab8-65 Ab8-66
Ab8-67 Ab8-68 Ab8-69 Ab8-70 Ab8-71 Ab8-72
Ab8-73 Ab8-74 Ab8-75 Ab8-76 Ab8-77 Ab8-78
Ab8-79 Ab8-80 Ab8-81 Ab8-82 Ab8-83 Ab8-84
 
Ab8-52 (with an ordinal number meant to draw our attention) is a variant of henua ora (i.e. marks the end of a cycle).
 
Ab8-60 and Ab8-76 (16 glyphs beyond number 60) are henua bent the normal way, reminding us about the 'shell of Tagaroa' (and in Ab8-63 we have pure).
 
Ab8-64 and Ab8-83 (19 glyphs beyond number 64) exhibit an unusual variant of henua with obliquely cut off bottom end. In the K text there is only one such glyph, viz. at the very end of the last (29th) period:
 
29
Kb4-10 Kb4-11 Kb4-12 Kb4-13 Kb4-14

Neither has Tahua any more glyphs of this kind. The creators of Tahua and the London Tablet text are using the same 'glyph vocabulary'.
