The lists of fossils from the Ruakokopatuna Valley, published by Waghorn (1927), agree very well with those described herein from localities of Nukumaruan age. Glycymeris waipipiensis Marwick is the only fossil which might indicate a slightly earlier age, and as Waghorn's estimate of a Waitotaran age was based purely on a 55 percentage of Recent species, it seems very probable that his faunas would be better correlated with those listed herein from Nukumaruan localities. That beds of Waitotaran age are present in the Southern Wairarapa seems undoubted, but in all other localities in the area they have proved, as yet, unfossiliferous, and bearing in mind the close relationship of the Ruakokopatuna fossils with those from Nukumaruan localities very near at hand, it seems best to regard his faunas as equivalent to those at the Junction of the Ruakokopatuna and Makara Streams and at Whangaimona, Palliser Bay.
