Aloe distans 'Variegata'
Variegated forms of plants often have slower growth rates { It's a lack of chlorophyll in the leaves thing} which can be an advantage when growing succulents such as this one as the plain green form is more likely to sprawl over the sides of the pot and develop unsightly dead leaves along an elongated stem in no time.
Avoiding a position full sun is probably advisable for this plant as it can be prone to leaf scorch but is otherwise easy care and can be left to its own devices with the occasional water as required.
As for the species name 'distans' , it may also be known as A mitriformis
