shear zones. They are, however, found all through the younger 

 greenstones and even in the older greenstones. In these rocks they 

 are accompanied by bleaching of the walls of the lode, owing to the 

 breaking down of the ferro-magnesian minerals with the formation of 

 pyrites. 



Both lodes and cross veins carry gold in payable quantities, and 

 both are worked in the mines. The workings have, up till now, 

 been confined chiefly to the oxidized zone, and have not anywhere 

 been carried far below it owing to the increased difficulty and 

 expense of working; they are, however, now being pushed further 

 down. 



The memoir gives a short description of the individual mines and 

 is illustrated by many figures and photographs, and is accompanied 

 by an atlas of large-scale geological maps on which all the details of 

 the structure are shown.

HE fossils described in this work have been collected from two 

 X series of beds. The one, occurring in the neighbourhood of the 

 Clarence River, south of Blenheim, yields a fauna characteristic of 

 the Lower Utatiir Group of Southern India. This fauna, which has 

 been recognized also in Zululand, Madagascar, Australia, Japan, 

 Queen Charlotte Island, Peru, and California, is approximately 

 Albian in age ; and it is of interest that Inoceramus concentricus, 

 so characteristic of the English Albian, is found in the corresponding 

 New Zealand deposits. The other series of beds, occurring in the 

 neighbourhood of Amuri Bluff, north of Christchurch as well as around 

 Christchurch itself, and south of the localities for theUtatur fauna, is 

 of Upper Senonian age and passes upwards into the Eocene. The lower 

 portions of these beds produces an Upper Senonian fauna comparable 

 with that occurring in the Ariyalur Beds of Sovithern India, in 

 Madagascar, in the Umzamba Beds of South Africa, in Japan, 

 Yaucouver, Chile, Southern Patagonia and Graham Land. 



The forms described from the lower fauna include two new species 

 of Trigonia, one of " Modiola ", one oi Lima, one of Aucellina, one of 

 Panopea, and a new variety of Inoceramus concentricus. From the 

 higher fauna one new species of Nuculana is described, one of 

 Malletia {Neilo), one of Barhatia, one of " Area ", one of Ciicullcea, 

 one of Fectunculus^ one of Trigonia, one oi Pecteji {Camptonectes), one 

 of Pecten {JEquipecten), one of Lima [Limatula), two of Inoceramus, 

 one of Astarte {Eriphyla), one of Anthonya, one of Lucina, one of 

 Cultellus, two of Callista {Callistitia), one of Panopea and one of 

 2%racia. 



The figures contained in the twenty plates are collotyped from
