The following information is from the secret US government document:

Examination of remains recovered from wreckage of UFOBs indicates that Extraterrestrial Biological Entities may be classified into two distinct categories as follows:

a.EBE Type 1. These entities are humanoid and might be mistaken for human beings of the Oriental race if seen from a distance. They are bi-pedal, 5 feet 4 inches in height and weigh 80-100 pounds. Proportionately they are similar to humans, although the cranium is somewhat larger and more rounded. The skin is a pale, chalky-yellow in color, thick, and slightly pebbled in appearance. The eyes are small, wide-set, almond-shaped, with brownish-black irises with very large pupils. The whites of the eyes are not like those of humans, but have a pale gray cast. The ears are small and not low on the skull. The nose is thin and long, and the mouth is wider than in humans, and nearly lipless. There is no apparent facial hair and very little body hair, that being very fine and confined to the underarm and the groin area. The body is thin and without apparent body fat, but the muscles are well-developed. The hands are small, with four long digits but no opposable thumb. The outside digit is jointed in a manner as to be nearly opposable, and there is no webbing between the fingers as in humans. The legs are slightly but noticeably bowed, and the feet are somewhat splayed and proportionately large.

b. Type 2. These entities are humanoid but differ from Type 1 in many respects. They are bi-pedal, 3 feet 5 inches to 4 feet 2 inches in height and weigh 25-50 pounds. Proportionately the head is much larger than humans or Type 1 EBEs, the cranium being much larger and elongated. The eyes are very large, slanted and nearly wrap around the side of the skull. They are black with no whites showing. There is no noticeable brow ridge, and the skull has a slight peak that runs over the crown. The nose consists of two small slits which sit high above the slit-like mouth. There are no external ears. The skin is a pale bluish-gray color, being darker on the back of the creature, and is very smooth and fine-celled. There is no hair on either face or body, and these creatures do not appear to be mamalian. The arms are long in proportion to the legs, and the hands have three long, tapering fingers and a thumb which is nearly as long as the fingers. The second finger is thicker than the others, but not as long as the index finger. The feet are small and narrow, and four toes are joined together with a membrane.

It is not definately known where either type of creature originated, but it seems certain that they did not evolve on earth. It is further evident, although not certain, that they may have originated on two different planets.

The Type 2 EBE bears a ckise resemblance to the alien bodies described by Glenn Dennis's friend on the autopsy table in Rosewell in July 1947, although she did not describe any peak running over the crown of their heads.
