55 mm); crown margins smooth or crenulated
, with very short and sharp marginal ridges; neck surface smooth, without vertical ridgelets; base up to three times height of crown; pulp opening situated posteriorly in base; most preserved bases of scales exhibit spur-like anterior process directed forward or forward and inward; microstructure of Thelodus type; dentine tubules varying from straight and fine, to rather wide in lower part of crown.
Diagnosis: Bagrichthys obscurus can be differentiated from its congeners in having the following unique combination of characters: a relatively small and narrow mouth opening, extremely reduced oral dentition, relatively short dorsal-fin spine with 15 or fewer serrae, both inner and outer mandibular barbels crenulated
, a slender body (body depth at anus 15.
clathurelloides (adults of both species having a maximum of about six teleoconch whorls), axial ribs are much finer in producta (20-22 on the penultimate whorl against 15 or 16) and markedly straighter, and the suture is crenulated
by the rib terminations in clathurelloides, but not in producta.
Plates, platelets, tesserae, and scales with dentine ridges overlying aspidine of middle and lower layers; ridges arranged concentrically on tesserae and longitudinally on scales; ridges with crenulated
margins, flat-topped or having longitudinal crest; orbits surrounded by one or more rings of concentrically placed units (plates or tesserae); branchial area covered with small units (i.
Specimens showing a strong degree of shell dissolution of the dorsal internal surface (interiors of such valves are sharply crenulated
and adductor scars are invisible) are characterized by a clearly visible V-shaped sessile septalium (Pl.
