There is a typo in image.py:671:

if MAGICK_VERSION_NUMBER >= 0x700:  # pragma: no cover
    IMAGE_TYPES = ('undefined', 'bilevel', 'grayscale', 'grayscalemalpha',
                   'palette', 'palettealpha', 'truecolor', 'truecoloralpha',
                   'colorseparation', 'colorseparationalpha', 'optimize',
                   'palettebilevelalpha')

grayscalemalpha has an errant m in it. It should be grayscalealpha.

Great find! This will be resolved quickly, and apart of the next release.
