The proper position of this genus is doubtless near the thick-billed genera such as Drymocataphus, but it is more convenient to place it here.
In Turdinulus the tail is reduced to a minimum in Length. The bill is of the same shape as that of Drymocataphus (fig. 41, p. 146), and the nostrils of both genera are alike. The rictal bristles are moderate.
