Retention of juveniles within the shell of the mother for some time after their emergence from the egg (ovoviviparity) occurs in several gastropod genera, and ddferent kmds of such brood protectIon have been outlined by Thorson (1946, p. 170, 186), Morton (1958, p. 124), and Fretter and Graham (1964, p. 155). Records of ovoviviparity in living members of the Turritellidae, however, seem to be quite rare, the only ones known to the writer being that of Peile (1922, p. 13) for t?e east AustralianTurritella gunniReeve and that of Iredale who supplied the specimens to Petie. Iredale (1924, p. 247) gave additional notes ongunniand proposed the genusGazamedafor it, citing “the characters of the protoconch, due to their viviparous habit” among the basic characters.
