age, although they are associated with a species of Spirigera and 
certain other fossils considered Paleozoic by Professor M‘Coy. 
The probably Jurassic strata of the Northern Island, near Waikato~ 
Southead, and at the Kawhia-Haven, contain an Ammonite 
(Ammonites Novo-Zelandicus, Hauer) intermediate between the 
species of the group Dentati and those of the groups Flexuost and 
Angulicostati, and a deeply grooved Belemnite (Belemnites Auck- 
landicus, Hauer) belonging to the Canaliculati, with shells of the 
genera Aucella, Placunopsis, and Inoceramus. Dr. Zittel states that 
the evidence of the Belemnite, the Aucella, and the Placunopsis is 
in favour of these beds being of Jurassic age ; while that of the 
Ammonite and the Inoceramus points to the Cretaceous period. 
Tertiary deposits, very rich in organic remains, occur in both 
Islands ; they may be divided into two groups, one of which contains 
no recent species amongst its fossils, and may therefore be considered 
to belong to the earliest portion of the Tertiary period ; while the 
other contains fossils, some of which bear a striking resemblance to 
species of the same genera now found in the neighbourhood, while 
others are identical with them: thus showing the same kind of 
relation that the Sub-Apennine fossils do to the recent Mediterranean 
species. Many of the genera represented have a very limited geo- 
graphical range, and thus the whole fauna has a peculiar facies, 
making it difficult to ascertain the age of the beds by comparing their 
fossils with those from the Tertiary strata of Europe.—H. M. J.

HE fossil Foraminifera found at Orakei Bay (or Creek), near 
Auckland, in the North Island of New Zealand, have already 
been briefly alluded to in the appendix to a paper by Mr. C. Heaphy, 
published in the Geological Society’s Journal, 1860, vol. xvi. p. 251; 
and this bed of fossiliferous green sand, or ‘ friable argillo-calcareous 
grit, full of green grains (the casts of small organisms, especially of 
Foraminifera), has yielded the numerous beautiful casts of Amphi- 
stegina figured and described in Dr. Carpenter’s ‘Introd. Study 
Foram.’ (Ray Soc.), 1862. These facts appear to have escaped 
Dr. Karrer’s notice. ; 
Dr. Karrer’s nomenclature of Foraminifera permits nearly every 
difference of feature in individuals being taken as the basis for 
‘specific’ distinction, as is still usual with some Rhizopodists ; but, 
if his ‘species’ be more strictly correlated with known forms, 
accerding to the English plan (see Carpenter’s ‘ Introduction’), we 
shall find many old acquaintances on his beautiful plate of fossil 
Foraminifera from Orakei Bay, although he admits but very few 
accepted names. With regard to generic relationship, we believe 
that he is mistaken as to fig. 9, which is Lituola globigeriniformis 
(not a new species of Textularia); fig. 10, Orbitoides (not Orbi- 
tulites), and probably, like fig. 21, the representative of O. Mantelli ;
