The Hanuman langur, Presbytis entellus (Primates, Cercopithecidae, Colobinae), is under investigation in its wild state around Jodhpur, Rajasthan, India, since 1967. Jodhpur constitutes its extreme western range of distribution beyond which lies the Great Indian Desert. Infant transfer, infant killing [see Mohnot, 1971a, b], and intergroup infant kidnapping were frequently observed in this habitat. Details pertaining to intergroup infant kidnapping by allomothers of neighboring groups are presented here.
