Humanoids
HUMAN TYPE A: These are of a genetic base similar to humans of earth.  They appear of "normal" height (5-6ft?) and tend to be fair-skinned with blonde hair.  These entities have been abducted by the  greys or are the offspring of abductees and have been trained by the greys as servants.  These entities are totally subservient to the greys.

HUMAN TYPE B: These are aliens of similar genetics to earth humans and also, it seems, of the humans that serve the greys. These are from the Pleiades and are also of the blonde, fair-skinned appearance.  This type is of a genuine highly evolved, spiritual, benevolent variety and have a kinship toward humans and are the only aliens to be truly trusted by earth humans at this time. They had at one time offered to be of assistance to earth leaders in dealing with the alien situation here but were rebuffed and so have taken a kind of "hands off" approach for the time being.  These aliens are supposedly the forefather race of humankind.  These are apparently not on earth much at this time due to serious problems in the area of their home.

HUMAN TYPE C: Very little is known about these.  They are supposedly another of the highly evolved, spiritual type of great benevolence to earth humans.  I understand that their appearance is similar to other human-type aliens. They are from Sirius and don't appear to be much involved with earth happenings at this time other than being concerned about the Grey scenario.  They could 
desire to be of help to humans. 

There are other known human type aliens of this "more highly spiritually evolved" nature that are apparently aware of the situation on earth and considering some possible course of action.  These are from Arcturus and Vega.
