Keywords:Schistura, Nemacheiline fish, comparative osteology, Meghalaya.
The present study is based on the comparative osteology among Schistura fishes with incomplete lateral line found in Meghalaya. Six species are studied for osteology, three already described ones and three unknown species. The clearing and staining of this species group showed variations and similarities in their neurocranium structure, ceratobranch structure, air bladder capsule structure, vertebrae number, fin insertions and caudal vertebrae complex in all cases. The study revealed that Schistura fasciata has a total of 37 vertebrae, S. reticulofasciata with 35–36, S. syngkai with 34–35, S. sp. 1 with 35, S. sp. 2 with 37 and S. sp. 3 with 32 vertebrae.
