Remarks. Silurus afghana is a synonym of Pterocryptis gangelica listed by Coad (1981) in Afghanistan. However, Silurus afghana is not identified as being from Afghanistan. It is from Assam, India. Afghanistan is not included in the natural distribution range of the species. The presence of the species needs clarification.

discussion
We treat the nominal species Pterocryptis gangelica Peters, 1861 and Silurus afghana Guenther, 1864, both of which are known from the Brahmaputra and Ganges River drainages in the northern part of the Indian subcontinent as conspecific. Pterocryptis material from northern India is poorly represented in collections and we could not distinguish between the small amount of material identified as either of the two nominal species. Kobayakawa (1989) diagnosed P. afghana as possessing tubercles on the snout, but our examination shows that tubercles are present on the snouts of all Pterocryptis species, although the tubercles are often small and may be obscured by a thick layer of congealed mucus in preserved material. Furthermore, the tubercles are easily damaged (e. g. when we attempted to remove the layer of congealed mucus by rubbing), making it more difficult to study this character. In summary, it is possible that tubercle shape may be useful in diagnosing Pterocryptis species, but its worth could not be fully assessed in our study. We note, however, that tubercle shape has been used as diagnostic characters in other catfish groups, most notably in sisorids (Mo & Chu, 1986) and moch
