The osteology of the head skeleton of marine catfish Arius tenuispinis is described in detail. The skeletal elements of the different regions are dealt with categorically. Bones of the ethmoidal, orbitotemporal, auditory, and occipital regions of the cranium; and the upper jaw, lower jaw, hyoid arch, hypobranchial, and opercular series of the visceral skeleton are described in detail. Identity of the ectopterygoid, mesopterygoid, and metapterygoid is established in accordance with the current nomenclature and accepted homologies. The shelving bone of the epiotic is found to be large, having articulation with the parapophyses of the complex vertebra. The head skeleton of A. tenuispinis conforms to the normal siluroid pattern.
