Described from one worker (holotype) taken by myself on Kartabo Point, at the junction of the Mazaruni and Cuyuni Rivers, British Guiana, August 20, 1935, and one worker (metatype) taken by myself in the foothills north of Tunapuna, Trinidad, B. W. I., July 29, 1935. Intensive collecting in both localities failed to reveal other workers and testifies to the extreme rarity of these archaic ants. Both specimens were among leaves and, as there were no land snails in either place, a snail-eating habit could not be inferred (cf. Creighton, 1928). It is more probable that the bizarre mandibles are used for capturing other Arthropods (cf. the myriapod-eating habit of
