56 J)R. HECTOR ON THE GEOLOGY OF NEW ZEALAND. 



Prom the comparison which this Table affords with the recent 

 fauna of the same area, the Otatara formation would seem to have 

 no claim to a place among Eocene formations. This is confirmed by 

 the occurrence of a few fossils of decidedly Cretaceous type, such as 

 Saurian forms and fragments of the shell of Inoceramus, and the pre- 

 sence of many forms that are associated with decided Mesozoic fossils 

 in the underlying strata. On the other hand, the occurrence of 

 decidedly Tertiary fossils (among which is Nautilus ziezac, or a closely 

 allied form), the gigantic Penguin bones, and the recent discovery 

 of the bones of a Turtle, also from the Seal-rocks, indicate a fauna 

 not dissimilar to that at present existing in adjoining areas to the 

 north and south ; so that any additional evidence bearing on this 

 matter, such as is afforded by Mr. Woodward's determination of the 

 affinities of this Crustacean, is an important contribution to New- 

 Zealand palaeontology. 



The accompanying section (p. 54) explains the general sequence of 

 the formations referred to in the foregoing paper on the west coast 

 of the South Island, from Brighton to the Alps.
