A third case was brought to my knowledge by Mr. M. W. F. TWEEDIE, Director of the Raffles Museum, Singapore, who kindly submitted me with three samples of millipeds which were observed migrating at Sungei Buloh Settlement, Selangor,
by Mr. J. L. HARRISON of the Institute of Medical Research, Kuala Lumpur. The samples contained specimens of three different larval stages, probably all belonging to one Harpagophorid species apparently of the genus Thyropygus Pocock
in its original sense. more exact identification being impossible by the absence of an adult male.
