The intrinsive muscles of the syrinx fixed to the ends of the bronchial semi-rings ; the edges of the mandibles smooth or the upper one simply notched; hinder aspect of tarsus longitudinally bilaminated, the laminae entirely smooth; wing with ten primaries ; tongue non-tubular and rather fleshy ; nostrils always clear of the line of forehead, the space between the nostrils and the edge of the mandible less than the distance between the nostril and the culmen ; plumage of the nestling streaked; rictal bristles present; sexes alike ; rectrices twelve ; first primary small; one moult in the year.
The only structural difference between the Eulabetidae and Sturnidae is the presence of rictal bristles in the former arid their more fleshy tongue. The genera Lamprocorax and Saroglossa are very like the birds of the genus Slurnia in all their ways and to some extent link the two families together.
