Two cases of double monsters from Barky (Libyan native breed) were studied.
The first monster appeared as a conjoined twin featuses with single head and of nearly similar shape and size. The two foeti were joined ventrally from the maniburum sterni to the umbilical cord. The second monster appeared as a single foetus with curved vertebral columon and double sets of fore limbs, hind limbs and two recti and double sets of external genitalia.
The monsters were photographed, radiographed and dissected. The observations are discussed in light of the available literature.
