The taxonomic status of a shrew species, Soriculus baileyi Thomas, 1914 (Insectivora, Soricidae) was re-evaluated on the basis of external and cranial morphological characteristics. Soriculus baileyi is considered a valid species of the subgenus Episoriculus. It is a large species with a tail shorter than or as long as the head and body length, and is distinguished from the other Episoriculus species, S. leucops, S. caudatus, S. fumidus, and S. macrurus, in having the combination of robust first upper incisor, long rostrum and upper unicuspid row, large tympanic ring, and high ascending ramus of mandible. Soriculus baileyi is known from Sikkim and Assam in India, Myanmar, and Vietnam. Morphometric variation among Episoriculus species is discussed based on principal component analysis.
