GD48 glyphs as a rule are not exactly symmetric. In e.g. Ab3-74 the lens-like shape is more convex at left:

 

In Aa1-45, which otherwise is rather similar to Ab3-74, the circumference is open at the bottom:

 

The variability makes it difficult to determine which glyphs belong to GD48 and which belong to GD86. I have therefore inserted a hyperlink that leads from GD48 to GD86 (and the other way around).

 

GD86 is more rounded than GD48, as Yc1-109 is a good example of:

 

The border line between GD48 and GD86 is, though, hard to define. Aa2-5 (which I initally classified as GD86, but now have reclassified as GD48) is an unusual glyph because it has not so sharp ends as other GD48 glyphs:

Furthermore it is shorter than normal. Possibly there is an influence from the preceding glyphs (Aa2-3--4):

 

I have decided to classify as GD86 glyphs - regardless of how rounded they are - oval glyphs with internal markings, e.g. Ab1-31:

 

I have also referred small oval signs to GD86, like those in the elbow ornaments in Aa2-12,  Aa2-19, Aa5-21 and Aa7-29 (even though their shape looks like GD48):

        

In the same manner I have referred to GD86 glyphs with similiar signs located at other places, as e.g. in Aa6-40:

Even after this problems remain. Aa2-72 and Ab7-16 exemplify these:

Obviously there may be allusions to GD48 at left top respectively at left bottom in these two glyphs. Aa2-72 is an unusual variant of GD24 and Ab7-16 an unusual variant of GD32. After some hesitation I have decided to classify them also as GD48.

 

But then Aa2-71 (immediately before Aa2-72) presumably also contains an allusion to GD48 (in form of the upraised arm):

Ab7-16 probably shows an upraised arm too. I will not use the same principle as in GD44 and GD45, viz. to disregard glyphs with possible allusions in form of wings, arms etc. Therefore I have classified these glyphs - Aa2-71 (GD15), Aa2-82 (GD11), e.g. Aa5-27 (GD52), and Aa7-43 (GD22) as also GD48:

        

It is somewhat easier to distinguish GD48 in the arms (wings etc) than to distinguish GD44 and GD45, because the shape is 'swollen'.

 

Though there are cases which do not belong to GD48 even if the arm is 'swollen', e.g. Ab7-49 and Ab6-26:

  

 

A few other glyphs I have classified as GD48 because they may contain the GD48 'swollen' shape, viz. Aa5-43, Aa6-71, Ab2-80 and Ab4-41:

        

 

There are a few clear cases of GD48 in mixed glyphs, viz. Aa2-18, Aa6-83, Ab3-71 and Ab3-73:

        

It must be remarked that GD48 often seems to be integrated in other GD types. We can for example compare Aa6-71 with Aa4-14 (GD21):

And we have such glyphs as Aa1-56 (GD16), Aa8-71 (GD17), Aa7-80 (GD38), Ab4-44 (GD47) and Aa8-29 (GD55):

           

It would be impractical to have all such glyphs classified also as GD48. And I have not inserted hyperlinks from GD48 to such GD which often contain these allusions to GD48.
