Cuauhtlan (Mdz24v)

There is another Cuauhtlan glyph, a compound glyph, in the Codex Mendoza on folio 13 verso. That one has an eagle's head and the two front teeth to stand for the phonetic -tlan suffix. There is also another Cuauhtlan glypn that is simply a standing eagle.
The differences of scholarly interpretation for this glyph are not great. Unlike Berdan and Anawalt, Karttunen does not see the locative suffix -tlan (which is supported by the teeth) as meaning a place of abundance of a certain thing. Karttunen preserves that reading for the locative suffix -tla. The gloss definitely supports the paleography of the -tlan suffix. That said, there are intrusive n's, and there is a noun "cuauhtla" (also spelled "cuauhtlah") which means woods, forest, wilderness, and could serve as a place name.
It is worth noting that this place name uses the -tlan postposition on the stem that once had the -tli absolutive (cuauhtli, eagle). Whereas, the place name Cuauhtitlan uses the -titlan postposition on the stem that once had the -tl absolutive (cuahuitl, tree). Whereas, the place name Cuauhtitlan uses the -titlan postposition on the stem that once had the -tl absolutive (cuahuitl, tree). But in the case of Mictlan Cuauhtlan (Mdz49r), the ligature is not used, so it must not be a requirement.
