As you know, the Khajiit come in different forms depending on the phases of the moons when they are born.

What subspecies are the ones living in Skyrim?

I think they are from the Suthay-raht subspecies.

Suthay-raht I think.

Edit: Khajiit- http://www.uesp.net/wiki/Lore:Khajiit
Skyrim Khajiit- http://www.uesp.net/wiki/Skyrim:Khajiit

I think it would have been interesting to see the other forms of Khajiit.

Thus why we need TES VI: Elsweyr.
