The subspecies found in India was earlier Tail carriage in non-human primates makes an designated as M. nemestrina blythii (Pocock, interesting study. Even sub-specific variations 1939), but Fooden (1975) considers it to be are often recognized on the basis of tail carriage, synonymous with leonina and the author has at least as one of the keys to identification. In followed the same practice (Choudhury, 1997). the case of the pig-tailed macaque (Macaca nemestrina Linn.), the tail carriage is significant In this brief report, the description of tail as is evident from its popular English name. carriage as observed in the wild in Assam, India, Fooden (1975) gave a detailed account of the is contradictory to the existing theory suggested tail carriage of three subspecies of Macaca by Fooden (1975).

M. nemestrina leonina carries its tail arched forward over its back, with the tip The survey of pig-tailed macaques was carried of the tail directed upward and forward, while out throughout northeastern India between 1986 M. nemestrina nemestrina carries its tail arched and 1999. However, detailed observations on rearward, with the tip of the tail directed tail carriage could only be made in the following downward. M. nemestrina pelops carries its tail areas of Assam: Innerline Reserved Forest (RF) almost like the nominate race. Groves (2001) of Cachar district (24°30' N, 92°50' E), has even suggested full species treatment to Garampani and Nambor Sanctuaries (26°25' N, leonina and the tail carriage was one of its 93°50' E) of Karbi Anlong district, Bherjan RF diagnostic features.

The habitat in all the localities was of tropical wet evergreen and semi- evergreen rain forests, on flat plains as well as hills. Results and discussion Fooden (1975) attempted to investigate the anatomical basis for such differences in tail carriage in M. n. leonina and M. n. nemestrina. His materials included embalmed cadavers of 3 adult male M. n. leonina, caudal vertebrae of 3 wild-caught adults (also M. n. leonina) and In India, the pig-tailed macaque is confined to caudal vertebrae of 2 captive sub-adults of M. n. the forests of northeastern India, only south of nemestrina. He observed that the intervertebral the Brahmaputra river (Choudhury, 1988, 1989, joints Ca 4-5, Ca 5-6 and Ca 6-7 in M. n. 1996, 1997).

Had there been such an anatomical ventriflexed to form the proximal part of the basis, they would have always carried their tails downward directed rail flexure, and the arched forward. Thus, perhaps there is no intervertebral joints Ca 7-8 and Ca 8-9 are also orientation of caudal vertebrae. flexed to complete the arch.
