Abstract
THE mechanism of hatching in the sheep tick does not seem to have been previously described. When freely laid, the eggs are oval, but deposition in crevices results in a certain amount of flattening. Examination of the egg under the microscope reveals that the brown colour is due to a thin semi-transparent shell, covering the brown internal mass. Each egg is surrounded by a gelatinous secretion produced by Gené's organ. Immediately after oviposition., the individual egg weighs 0·00006 gm.
