cilin (Mdz12r)
This simplex glyph for small turbinate shells called cilin doubles as the glyph for the place name for Cillan. The glyph consists of a cluster of six shells, all drawn with black and left natural/white. They spiral at one end.

The cilin is a small conch shell. Wimmer's dictionary (2004) notes that it has sometimes been translated as "snail shell." See below, right, for additional varieties of small shells. And note how the shells that splash off water glyphs resemble the cilin. And the cilin seems quite similar to the cuechtli.
c. 1541, but by 1553 at the latest
