Some of the recent shells of this list may have been wrongly 

 named, but it must be noticed that of the 32 named species 

 of Mollusca (including the variety), all but Struthiolaria pajm- 

 losa, Cerithium cancellatum, and Trigonia pectinata have been 

 found in Pareora rocks in other places in New Zealand ; 

 and, of the exceptions, the first two occur in the Wanganui 

 System, while the third (doubtfully identified) has not been 

 found in any other part of New Zealand, Of the 29 Pareora 

 species, 14 are not known older than the Pareora, 5 are not 

 known younger than the Pareora, 7 are found in the Pareora 

 only, and 3 go through all our tertiary rocks. Aturia ziczac 

 occurs in New Zealand at Waihao Forks, with numerous 

 Pareora fossils. The genera Cominella and Ancillaria are not 

 known from mesozoic rocks in any part of the world. Entalo- 

 phora zealandica is found at Wanganui, and in miocene rocks in 

 South Australia, Trochocyathus rnantelli occurs in the Pareora 

 beds at Mount Horrible, near Timaru,
