Fig. 15D .

Material.— One specimen, NMNZ S.52749, Home Hills Station, Manuherikia River near St Bathans, Otago, HH1a bed, Bannockburn Formation , early Miocene .

Remarks.— Lactarius sigmoidalis represents a common species in the late Oligocene and early Miocene of New Zealand, ranging stratigraphically from Duntroonian to Lillburnian (about 25 to 12 Ma). It is thus of limited stratigraphical relevance.

Stratigraphic and geographic range.—Bannockburn Formation, Manuherikia River ; otherwise in marine strata of New Zealand from Duntroonian, late Oligocene, to Lillburnian, middle Miocene of Canterbury, Otago and Southland, southern Island, New Zealand.
