How can I fix this error?

Python

This is the code:

class Race(Sentient):
    def __init__(self, special_abilites={}, Race_Strength=0, Race_Dexterity=0, Race_Constitution=0, Race_Intelligence=0, Race_Wisdom=0, Race_Charisma=0, speed=0):
        self.special_abilites = special_abilites
        self.Race_Strength = Race_Strength
        self.Race_Dexterity = Race_Dexterity
        self.Race_Constitution = Race_Constitution
        self.Race_Intelligence = Race_Intelligence
        self.Race_Wisdom = Race_Wisdom
        self.Race_Charisma = Race_Charisma
        special_abilites = {}

Darkvision = ("None", False)
Stonecunning = ("None", False)
Stability = ("None", False)
Poison_Resistance = ("None", False)
Spell_Resistance = ("None", False)
Goblinfoe = ("None", False)
Giantfoe = ("None", False)

Human = Race(None,1,1,1,1,1,1, speed=30)
Dwarf = Race(special_abilites={Darkvision:1,Stonecunning:2,Stability:3,Poison_Resistance:4,Spell_Resistance:5,Goblinfoe:6,Giantfoe:7})

if Darkvision in special_abilites:
    Darkvision = ("You can see 60ft in the darkness", True)
if Stonecunning in special_abilites:
    Stonecunning = ("You can notice unusual stonework", True)
if Stability in special_abilites:
    Stability = ("You are much harder to topple", True)

It gives this when run:

Traceback (most recent call last):
  File "DnD game engine.py", line 149, in <module>
    if Darkvision in special_abilites:
NameError: name 'special_abilites' is not defined

I don't know if it's something simple I haven't caught or something else, any help is appreciated. Thanks!
