: Mr. Jerdan, in a series of papers in the thirteenth volume of the Annals of Natural History, has described forty-seven species of ants in Southern India. But M. Nietner has recently forwarded to the Berlin Museum upwards of seventy species taken by him in Ceylon, chiefly in the western province and the vicinity of Colombo, Of these many are identical with those noted by Mr. Jerdan as belonging to the Indian continent. One (probably Drepanognathus saltator of Jerdan) is described by M. Nietner as "moving by jumps of several inches at a spring."
