ɤ

Etymology
From a small-cap Ɐ.

Symbol

 * 1)  a.
 * 2)  -coloring or a weak, fleeting, epenthetic or echo.

Usage notes
Sometimes mistaken for or replaced with the velar consonant letter Latin gamma (ɣ), which unlike ɤ drops below the baseline. The old 'baby gamma' form was changed to the modern form to help avoid such confusion.
