The Male Genital System of the Scorpions, Buthus quinquestriatus

A. ABD-EL-WAHAB PH.D.1

1 Institute of Animal Genetics, West Mains Road, Edinburgh

1. The paper consists of a morphological and histological description of the male genital system of the scorpion, Buthus quinquestriatus (H.E.).

2. There is a well-developed ganglionic mass at the extreme end of the lumen of the cylindrical gland. This ganglionic mass has not been recorded by any of the previous authors.

3. There are two pairs of annex glands opening into the common genital chamber. None of the previous authors have observed such a gland with the exception of Pavlovsky (1915), who recorded it in B. australis.

4. New methods have been adopted to resolve the structure of the ejaculatory organ and its supporting shaft. The organs were cut in serial transverse sections, and whole mounts were also made.

5. In the supporting shaft, several basal processes have been found, namely, the oblique vertical, longitudinal, superior, and inferior outer and inner processes.

6. The supporting shaft is found to be of a chitinous nature.
