the unstained section. The pyroxene is a pale weakly pleochroic aegyrine 
augite, occurring rarely in small idiomorphic phenocrysts, but generally i in 
minute prisms without terminal faces, or in less regular wisps. Magnetite 
occurs rather more abundantly than is the rule in. Dunedin роодо 
ranging from very small grains to those about O'l mm. in diameter. 
Possibly this mass of phonolite is the continuation of the much thinner 
flow of phonolite described by Dr. Marshall (1914) near the base of the 
great series of flows at North Otago Неайѕ—7.е., about a mile farther to 
the north-east. Several intermediate outcrops of phonolite have been 
found suggesting this." 
The Dowling Bay limestone is rather rich in shells, but, mei ao mi 
ost of them are зра rolled or fractured. The fossils 
teristic black or rusty crystalline appearance. In many ot them the 
ornamentation is obscured, and frequently much excavation of the matrix 
is necessary before any identification can be made. The limestone is 
generally compact, the shells mostly occur in ti» carbonaceous beds which 
do not split out easily, and the exposure of complete specimens is of rare 
occurrence. 
It has been possible in almost every case to compare the species 
identified from Dowling Bay with actual specimens from Oamaru, especially 
Target Gully, in the author's cabinet, and so it is hoped that as few errors 
as possible have been incurre 
A definite idea of the horizon of this bed may be obtained most readily 
y tabulating records and estimating percentages after the methods of 
Marshall (1919, p. 247) and Thomson (1920, pp. 389 et seq.).
