SUMMARY A new species and genus, Pumilus antiquatus, of kraussinid brachiopod from shallow water, Lyttelton, New Zealand, is described and figured. It is characterized by the possession of a schizolophous lophophore in the adult, supported by both divergent lamellae and spicules: the shell is smooth, less than 5 mm. long and strongly sulcate. The gonad is hermaphrodite. Notes are given on the ciliary feeding mechanism. The affinities of P. antiquatus are briefly discussed: it is placed in the Kraussinidae.
